Excellent wedge. See my suggestion for preventing your LO from sliding down

I bought 3 of these – one for each twin’s crib, and another one for the changing table. Mine came as a two-piece foam and it was no problem aligning the two pieces together. I keep these under the sheet+ waterproof mattress cover, and the “seam” between two pieces of foam is no problem with this setup.We also had the issue of our girls sliding down on these after a couple of hours. We tried rolling a towel and tucking it in as a “U” shape and that didn’t work. But we finally figured out a way to keep our girls in place: rolling a towel into a “Y” shape and placing our girls into the “fork” of the “Y”. This prevents the sliding. Here’s how we do it, also pls see the uploaded image. I recommend using a fluffy bath towel(i think these have more “grip” to them); also, I do swaddle my LOs before placing them in the crib:- Take a towel, unfold it and lay it out flat- roll from one side, widthwise, until the middle of the towel- roll from the other side, widthwise, towards the roll #1, until the middle of the towel- take a velcro strap, a ribbon or something similar and tie one end of the towel to hold the two rolls together and prevent them from unraveling. Where exactly you place the tie depends on (1) the size of your towel, and (2) the length of your kid. Your towel should resemble a “Y” shape now- flip your towel over, so that the rolls are facing down, not up, place the towel into the crib and unroll slightly to allow for the width of your kid- When I put my LOs to bed, I typically align their shoulders with the top of the towel. They stay in place and don’t move.

Slept through the night since day one of using this…….

I took away a star only because the wedge isn’t lifted enough. Likely my fault it lists the description but my pediatrician said my 4 month old needs to be at a 45 degree angle, this one is about 30. She appears to be doing fine with that. It fits perfectly under her crib sheet. I have no idea what the issue is that everyone is talking about with regards to the zipper. No problems here. It fits the exact width of her crib so there’s no worry about her rolling off the crib wedge. Here’s a couple of things that I had to do:1) The crib sheet tends to loosen with my baby in her crib. So I invested in fitted sheet holders that clamp the corners together so they do come loose. Easy to find at any target or here on Amazon.2) My baby wiggles around like crazy! There’s no strap to keep her in place so I did what the nurses did at the hospital during her stay: take a towel and roll it up. Make it into a big ‘U’ and put it right where she sleeps. She sleeps in the wedge, right in the middle of the ‘U’ Shape! Prevents her from rolling from side to side or sliding off the wedge. It’s way less expensive than paying $80++ for the other ones online.

I am not exaggerating – this stupid wedge almost killed my 2 month old! We wrap a blanket around the edges of the crib, as the hospital taught us to do, so that it does not move. We did that on the first night using the wedge. To my absolute horror, my baby slid down the wedge and his entire head was trapped underneath the blanket. He was swaddled so could do nothing about it. HE COULD HAVE SUFFOCATED!!! This seemingly innocuous product should be removed from the market. I wanted to help my baby sleep, not kill him. Days later and I am still sick to my stomach over it.

flame retardant foam for baby

It really upsets me that this product is sold for babies when it is a piece of flame retardant treated foam covered in vinyl. I will keep looking for a different product to use for my baby’s crib, and I hope enough people will refuse to buy unsafe products so that manufacturers start providing us with better options.

Good for reflex – Bad for rolling….Sorta dangerous

I bought this wedge because my baby was choking/gagging everytime she was laid flat even when she was upright for 40 minutes after feedings. It does help somewhat for reflux – she didn’t spit up as much since we’ve been using. HOWEVER – a new problem since using this is that she ROLLS down the wedge (even when she was only a week old!!) and ends up at the bottom of the wedge, on the flat part of the mattress. TWICE I found her FACEDOWN on her belly at the bottom of the wedge or halfway down the wedge. Which is not a great way to prevent sids…Mine came with two parts that fit in the cover and has a zipper…It does fit the entire length of a crib or pack and play, and even if your mattress/crib is a little larger, it goes UNDER the mattress so it shouldn’t matter if it is a little small.I would LOVE to figure out how to get her to STOP rolling down the wedge – I roll up a towel/blanket and place it under her booty/legs in a U shape, but I worry about her putting her face in the blanket/towel too. So either way… kinda dangerous. But I’m afraid to keep her bed flat because of the choking/gagging…If I find something that helps, I’ll add to my review…I like this, it is useful to reduce reflux, but the rolling down it (even though it doesn’t make the mattress incline that much!!) is really a problem too!

So helpful for colds, fussiness!

Baby had a cold and was already a fussy little one!Doc suggested inclining him to help keep his nose drained… so we accidentally found out this helped with his fussiness also!Only thing I don’t like… It’s not Organic 🙁 and with all the time they spend sleeping, that’s a shame. As we did go for the Naturepedic line of crib mattress.

Alicia Hartford, AL

Not worth it!

Purchased this item since my daughter has acid reflux and can not sleep laying flat. I was unsure how she would do with it so we just tried it at nap time. Everytime we put her down it wouldn’t take her long to slide down and almost into the bumper (she is only a month old). Even if we took the bumper out I am not going to let her slide down and hit her head on the railings. This product is a waste of money!

Annette Oxford, FL


Save your money and roll up a towel or use an old phone book (remember those?) and place it under the crib mattress to elevate the head. Once your baby is old enough to scoot around, he or she will slide down off this wedge or worse, off the side.

Jessica Edmeston, NY

Worked for a while

This works well for babies with reflux as long as they stay still. Once my daughter started to move around, she ended up sliding down the wedge. Then it’s more of a burden than a help. So I’d recommend this to someone whose baby is diagnosed with reflux early. It is a great angle and very sturdy.

Good price, but be careful!

Our 3 month old daughter has horrible GERD since birth. She’s on meds, special formula, cereal added, we keep her upright for feedings and for an hour afterwards, etc. We were able to raise the head of the bassinet which she quickly outgrew, but not the new crib. Our pediatrician whose son also had severe GERD basically said good luck because she’s going to probably have to sleep in her swing until she’s a year old. No way do I want to do that! It’s fine for a nap, but she never sleeps as deeply in her swing and she really needs to be trained on good sleep habits like all other kids or she’ll have problems all her life (and I’m speaking from experience, I had her same issues as a kid and have had lifelong insomnia — now I know why). This under the mattress is working well for us for right now. During the transition from the bassinet, we had to put this in the middle of the crib for a few nights with a towel around her to keep her from sliding down and from freaking out. The first night we didn’t do this and it was a disaster even though we’d introduced her to the crib earlier with no problems. She moved in her sleep and when she couldn’t figure out where the heck she was with all this space and even with my picking her up immediately (we co-sleep in the same room with her) she screamed and fretted for a good hour (staring at me as if she wanted to make sure it WAS Momma and nothing else had changed! so sad but adorable at the same time!).When I went to remake the crib once she was used to it (we just kept spreading the towel around her until she was used to the extra room, it took 3 nights) and I moved the wedge up, there was a VERY unsafe gap. While someone (MIL….sigh) suggested that if I *had* to ‘mess with it’ to just roll up towels, but this is so not a good idea. Very dangerous! Instead I put this under the mattress and it solved the problem even if the angle doesn’t seem to be quite as high. As far as wedges go, this is a decent price although the price fits the cheap quality (two pieces and it off gases terribly). We’re going to replace this as soon as we find something that works better (and is safer and made with better materials).So yes, it works, but I can’t recommend it.

A must for reflux babies

I know they say nothing in the bed BUT if your baby has reflux, you will love this thing like I do. It gives our baby just enough of a head lift that this mommy gets some peace of mind.PROS: Easy to wipe cleanFirmCONS: NAWould I recommend it? YES! Definitely for babies that spit up allot or suffer from reflux.

Taylor North Henderson, IL

Not comfortable or safe

This does its job of lifting my daughter’s head during short naps… during longer sleep periods she just rolls to the bottom and ends up laying flat. The product info does not tell you that this is foldable and has a zipper in the middle… which means that there is a really hard, uncomfortable bump in the middle of the bottom where the zipper ends. Baby has to be placed to one side and not in the middle of the crib to avoid lying on the bump. Also, the width is narrower than my crib mattress, so there are unsafe gaps at the sides. Not good since baby has to be placed closer to the side. And since there is nothing to secure the wedge to the mattress, a tight crib sheet makes this scoot away from the head of the crib, leaving an unsafe gap there, too. Overall, I’m pretty disappointed, but at least it was cheap (and a gift). I’ll keep using it until I find something better. Notice that another person posted a picture showing the two different versions of this wedge… I would suggest finding a store to buy at rather than ordering from Amazon, since you don’t know which one they will actually send you. The foldable one is no good!

Kerry Pilger, NE

so bad

I put it under bed for my infant son and he just went right off it. pointless item. I just wanted something to have where his head is a little more up. going to have to find something else…..

Not big incline, doesn’t fit cradle.

This product is good for what it describes "for crib mattress". I wanted a sleeping wedge for a cradle, but this is much to wide to fit a cradle. But I made it work. It comes with two wedges which are placed inside a water-proof, zippered liner. I made it work by removing one wedge and placing it under my own waterproof cradle mattress cover. It’s not perfect but will work. Not a huge incline, I may see how new baby does with one wedge, and possibly stack both wedges together for more incline.

Helped reflux baby transfer to crib

Our son had reflux, so he slept in a Rock and Play rocker bed for the first 6 months. When we tried to transfer him to the pack and play or crib, he just screamed and cried and did not sleep more than 30 minutes at a time (with protest!). Since he was able to sit up and his legs were starting to hang out the end of the Rock and Play, we had to do something!We bought this wedge (which came in one piece unlike some of the other reviews) and put it under the mattress on the pack and play. We then took two rolled up towels and put them under the sheets on either side of our son. This recreated the feel of the Rock and Play and he slept in it the first time we tried! We also let him play in the pack and play for the few days before the wedge arrived – hoping to create a positive feeling about the thing before having him sleep in it.I know we’re lucky he slept in it right away, but without the wedge and the towels, he would not sleep in it! So, it worked for us. Also, he is now 7 months (two weeks sleeping with the wedge in the pack and play) and he does not slide off the wedge. Not to the side or the bottom. We will slowly start to remove the towels (use smaller ones…) and then eventually remove the wedge. But for now, it works great.A note: If you are expecting this wedge to be high enough for the recommended reflux elevation, it isn’t! It is fairly subtle in terms of lift. So, if your child is still dealing with reflux and needs a significant incline, read the details so you know what you’re getting.

Baby Slides Off

My daughter has reflux and we purchased this wedge in the hopes that she’d be comfortable sleeping on her back in the crib while slightly elevated. This is not helpful. We placed it under her sheets and mattress cover but all my daughter did was slide right down or off to the side. You can probably get the same effect from strategically folding towels. I wouldn’t recommend this to help your baby with reflux sleep.Ultimately, we purchased the the Fisher Price Rock ‘n Play for our daughter instead after reading a bunch of reviews from parents with refluxy babies and our daughter LOVES it. It sits at an angle, cuddles the child’s sides, and allows you to physically rock the baby back and forth as she goes to sleep. Unhappily, our girl loves it so much that she’s still sleeping in it at 8 months and we can’t figure out how to get her to a crib — but the wedge isn’t the way to do it.

Dorthy Glenview, IL

very nice!

the box is too big, but, the product is excellent. The inclination is 30 degrees, perfect for the reflux’s problem of my baby boy. I recommend to the parents, wrapping the pillow, because, the pillow fabric can warm the baby’s head.

Baby rolls off

My doctor recommended putting my babies at a 30 degree angle due to acid reflux. I purchased this but my babies roll off completely. I tried putting all kinds of padding on it, but my kids still roll off. Its just not comfortable, I am sending it back.

Emma Aniak, AK

Does what it should!

If you want the added security and comfort against all the SIDS scares out there…..This wedge is perfect to lean the baby up just a bit. Fits well under neath the mattress pad.Arrived quick!I would definitely recommend this.

Kara Queenstown, MD

Does the job!

I purchased this for my son and loved it. This model when I purchased it came in two pieces which you insert into the cover which is waterproof. Mine had no zippers, just a hole on the back to allow for the pieces to slide into. I used it with my first son from birth and he slept great. I also used half of it in our bassinet under the sheet with positioners ont he side to prevent rolling and he rarely spit up or had problems digestive problems while sleeping. I thought my son had outgrown it and gave it to a relative, but I’m buying two more, one for my son, and the other for our second baby due this July.

Great for reflux babies

My 1 month old has reflux and this wedge has been a perfect compliment to his medication. It easily fit under the Ultimate Crib Sheet (we always keep one on top of his bed sheet) and stays in place. He does roll off of it sometimes but it doesn’t affect his sleep. The main reason we got it was for him to be a little upright after feedings so it doesn’t matter that he doesn’t stay on it all the time; he easily falls asleep on it without his reflux acting up and that is what we wanted. There have even been nights where he wakes up and I place him back on the wedge and he immediately falls back asleep – he loves it! I highly recommend this crib wedge if your infant needs to be upright for a bit to help alleviate reflux.

Gale Keams Canyon, AZ

not what we expected

The wedge has a pretty big bump where it meets the mattress and our son just slid down the side of it. We only tried using it one night and then took it out. I would not recommend it.

Alice Bath, IL

Save your $$$

When I received this wedge, I was surprised by hom flimsy it was and how small. Would not recommend using it in crib, since baby can easily roll off either side (It does not fill the with of the crib by far). It comes in two pieces, we ended up putting one in the stoller bassinet and one under the mat of our child’s activity gym, and have to keep watching him while he is on it since he can roll off so easily. What did work for us was to elevate the crib mattress by just placing a few towels underneath, much better solution than this wedge.

Gail Colfax, WA


This is a great option for parents who worry about their babies sleeping too flat. I was worried because some of the reviews aren’t so great but I honestly don’t see why it didn’t get perfect reviews. Yes there is a zipper but its on the back so there is no way it would bother baby. Also it is very firm like a mattress so even under the sheet there is no way it could cause anymore concerns than the mattress would cause…it is nice and firm and fits the whole width of the crib. Also I like that it has two pieces (that fit very snug in the cover) also I like that if I want to take one out and fold the other half of the cover under and it can go under the sheet in our cradle and fits perfectly. For the first few months of babies life we will be using a different sleep positioner that has velcro sides and is also elevated that fits nicely in the cradle on top of the sheet and with baby being swaddled it keeps him nice and secure between the positioner. But once baby starts wiggling a lot and trying to move he will move into the crib with this positioner or stay in the cradle with this positioner in place of our other. I will probably keep it in the crib until he is 1 or 2. It is a great little invention.

Yesenia Bryceville, FL

Great solution!

We purchased this item because our 3 week old was spitting up every time he laid on his back. The item came in two pieces with a zipper case. It wasn’t difficult to manipulate the second piece so that the two angles matched. If you’re having issues, make sure you put in the second piece right-side up! The zipper does go down the middle but is not noticeable once you place the wedge under the mattress or sheet protector. Would absolutely recommend to anyone having spit-up issues!

Sharron Dupuyer, MT

Mom at Ease

Baby loves this in his crib. It fits snugly under the fitted sheet, and allows him to lie in his crib at a slight angle, which helps if he has a cough or a lot of spit-up, and it makes me feel at ease.

Esmeralda Chadwick, MO

Safe and easy to use wedge

Wish I would have known about this during those nights when my kids were so sick and I was trying to wedge pillows and the like under their mattress. This keeps them upright, and fits perfectly across the crib, leaving no room to suffocate or get stuck. Washable and not too high. I use this thing a lot, when baby has just a bit of a runny nose, and I want to make sure it does not get worse. So much safer than using pillows under the cribsheet.

Amber Bates, AR

So far, so good

I also purchased this exact item from Babies R Us for $16.99 only, so I would not recommend buying it for the $39.99 price. It seems like Amazon sells it for $13.99 only, but is currently out of stock, so if you can, wait for it to come back in stock or go to BRU instead!Like others have mentioned, my wedge is only one piece, not 2 with a cover and zipper or whatnot. There’s nothing else that comes with the one wedge, and it does look exactly like the picture above. My son has only slept on it for a little while, so I can’t say for sure if it’s doing anything yet, but with his reflux and constant burping/spitting up even up to 1-2 hours after a nap, I don’t think any sort of incline can hurt him at this point. I also use rolled up blankets to secure him in place, so he doesn’t slide downwards, and it works just great.The wedge is a really sturdy piece of foam, and it almost matches the firmness of my son’s crib mattress too, theColgate Classica I Foam Crib Mattress, White, which is kind of nice. Overall, no complaints about this wedge. Not 100% sure if it works well yet, but for the price, I’m happy to try it out if it can do anything for my son’s sleep.

Jeannine Nabb, IN

Love It!

We were skeptical about purchsaing this product due to the negative reviews…but so far have been very pleased. When adding the second wedge we were very careful and have had no issues with seams or zippers. Our baby has reflux and would spit up all over when flat on her back- this has helped her not spit up as much (and be much more comfortable). While that was our main purpose, it has other uses that are great- such as when our baby is stuffy (cold) this product has helped her to breathe easier and is a great way to do tummy time. The only draw back was that she would slide down it- but that was an easy fix (we rolled up small towels and placed them next to her to prevent her from sliding). I wish we would have purchased the product way before we did.

This seemed to help my oldest son who had colic as an infant. It always made me nervous though so I only used it when I could keep a close eye on him. I initially bought it use in our pack n play and never used it that way it just seemed too scary. I did use it in our crib which seemed more secure.
