"The SleepCurve® mattress is amazing, it ticks so many boxes!"

"I initially decided to try the moses mattress as Elwood developed a slight flattening on one side of his head and I was told that the mattress could help, which it has, but it’s the other benefits which I like, for example when Elwood caught his first cold, the mattress was perfect for positioning his head so his airways were free and his sinuses never blocked. Day time was hard for him, but when night time came he slept right through. I highly recommend it"
Sherri Tai-Chidlow, mum to Elwood

Keep baby cooler and more comfortable

Your baby’s temperature is very important and care should be taken to avoid overheating. Ordinary cot or crib mattresses trap the heat against your baby’s body and head leading to discomfort. SleepCurve® mattresses feature intergrated, rounded channels so excess heat can escape, leaving your baby comfortable and happy.

Aid breathing and promote better posture

When a baby is lying on their back on a flat surface, the head is tilted down with the chin touching the top of the chest. This isn’t natural because it constricts the airways and a baby breathing like this is more likely not to sleep through the night. A SleepCurve® baby mattress allows the head to rest in a natural neutral position with the airways completely clear and babies breathing this way will be more comfortable and more likely to sleep through. Parents tell us that their babies sleep more peacefully and when babies catch a normal respiratory infection, they are less affected because the airway is in the natural, open position.

Clinically proven to remedy and prevent Flat Head Syndrome

In a recent clinical study by Alder Hey Children's Hospital, 29 out of 30 babies with Flat Head Syndrome showed significant* improvement in head shape (cranial vault asymmetry) after using a SleepCurve® mattress. The report concluded that the SleepCurve® mattress produced similar results as a baby helmet for treating Flat Head Syndrome. The authors also commented on how much more cost effective the mattress was (as well as being less obtrusive and more comfortable for baby).
*Average head asymmetry fell from 16mm to 5mm over the 6 month period.

Reduce Reflux for a better nights sleep

Acid reflux or posseting is unpleasant for your baby and is the cause of many a disturbed sleep. A SleepCurve® mattress has a gentle slope down towards the feet designed to help your baby, whilst still being totally comfortable and allowing your baby to sleep in a natural, comfortable position.

Allow baby’s head to move freely

All babies’ heads have a pronounced bulge at the back. In the early weeks of a baby's life the shape and weight of the head is too much for the undeveloped neck muscles to control movement. As a result babies lying on a flat mattress will end up with their head turned to one side or another. The unique hollow of a Sleepcurve® mattress allows the baby’s head to turn more freely, which has benefits for the spine and the muscles around the spine as well as the neck muscles.

Product Description

The SleepCurve® Cot Bed Mattress is suitable for babies who are too big to sleep comfortably in a crib or moses basket.The unique design delivers ultimate comfort for babies and peace of mind for parents.

The SleepCurve® Cot Bed Mattress features a movable curve that has four levels of adjustability. As your child grows, the curve can be moved along the length of the mattress, allowing it to be positioned in the correct place underneath the child’s head whilst their feet remain at the base of the cot in accordance with the FSID recommended ‘Feet to Foot’ guidance.

The pack includes a mattress with a pre-fitted hypoallergenic, anti-dustmite and washable mattress protector and two fitted sheets. You can also purchase additional sheet sets if required.



Mattress Size: 70cm x 140cm 


Common Questions

Is there any independent clinical proof of the effectiveness of the mattresses?
There has been a clinical study of the mattresses by Alder Hey Children's Hospital. They found that 29 of the 30 babies in the study had a significant improvement in head shape over the 6 month study period. The average was a 11mm improvement. The report concluded that SleepCurve mattresses were an 'effective treatment' with results similar to a baby helmet but at a fraction of the cost.

If my baby rolls over and doesn't stay with its head in the curve should I stop using a SleepCurve mattress?
There is no evidence of any detrimental effect of using a SleepCurve mattress once your baby can roll over independently. However, if your baby moves a lot or is rolling over regularly then we recommend that you review the use of the mattress. If your baby's head is not in the curve in the correct position the positive benefits of using the mattress are lost.

  1. Seems good on the first appearance 4 Star Review

    This mattress seems good quality and well made. It does have a smell when you first open the packaging, so I would let it air for a while before letting your baby use. I have been using for about 5 days now and I am happy with it. My baby was abit unsettled for the first night but this was due to a change in cot and position of his head, he has since got used to it and seems comfy throughout the night. I am hopefull that it will help with his flat head.

  2. Not as good as Moses 3 Star Review

    Moses sleepcurve was fantastic really helped baby's head and appeared to be very comfortable. However the cot bed matress doesn't appear to be as good material.... very cheaply made. Also the curve for the head isn't as big as the Moses one which seems a bit silly as obviously the head will get bigger the bigger the baby gets. Overall still wouldn't be without it as it really improved baby's flat head on one side as she has always had a favoured side. But feel this matress is overpriced considering the quality of material.

  3. Really makes a difference 5 Star Review

    Our son was born with a cyst on his brain which in turn caused flat head. We were using the Mimos pillow which our son kept rolling off and it did make his ears stick out possibly due to the shape.
    The mattress arrived next day delivery. Product was immaculately packaged.
    If can suggest spending that bit more purchasing the sleep curve mattress you won't regret it. Within two week we have noticed a massive difference in his head shape and his ears no longer stick out. Amazing product and worth every penny.

  4. Get into the groove! 4 Star Review

    I bought the cot bed mattress for my six month old, who started sleeping in it last week. In a rather comedy style, he managed to wriggle his full body and head into the groove in his first try! He sleeps properly in it when asleep but still manages to get into the groove when awake!

    I bought the mattress to address his moderately flat head at the back. One thing I have read elsewhere is whether the curve can make an impact in reshaping his whole, rather large, head. It is early days so we will have to wait and see.

  5. So happy I discovered this mattress!!! 5 Star Review

    I spent ages searching the internet for information on flat head syndrome as I had noticed that my 10 week old had significant flattening on one side as he prefers to look one way. Having mentioned my concerns to health visitor, I wasn't happy just to leave it alone and hope his hair will hide it when he's older-had tried everything to try to encourage him to look the other way etc. That's when I looked into mattresses and flat head syndrome anf came across the sleepcurve mattress and didn't hesitate in buying one. My little one has slept on it for just under a month and I can honestly say that his little head is rounding out beautifully and he sleeps so well on it to; can't recommend this enough-was beginning to think I may have to go down the helmet treatment route to ccorrect but thanks to the sleepcurve mattress this won't be necessary.

  6. Results for flat head seem to appear quite quickly 4 Star Review

    Our son is 6 months old and was born with quite a misshapen head due to how he was lying inside. He also had torticollis and therefore favoured sleeping on one side resulting in a flat head to one side. We bought the mattress to try and correct this and because there had been people whose babies slept through the night because of the mattress. We have noticed, after a week and a bit, that his head is already changing shape. On the sleeping front it has made no difference whatsoever...guess you either get a sleeper or you don't!

    My only complaint is that the last position you use (which we use now as he sleeps in a sleeping bag so no need for feet to foot) is quite a way from the top of the cotbed - much further than where your head would normally be on a bed. This means that when he is older, we will have to revert to our old mattress so that he gets the full use out of the cotbed. I would also like the sheets to be a bit softer if you HAVE to use them with the mattress. I did try our original sheets but they don't 'dip' into the curve so i'm guessing they could be a suffocation hazard.

  7. Cot bed bliss - suitable from newborn with promising results 5 Star Review

    Our son Jim's already in a cot bed at 8 weeks as he was born with torticollis (twisted neck) and a plagiocephaly (flat spot) on the front of his head. Upon seeing an osteopath sleepcurve was highly recommended. The website states a cotbed mattress is suitable from 9 months but Jim is already too long for the the shortest curve setting so the manufacturer may want to review this. It's easy to use, baby sleeps well and we're already seeing benefits to skull shape alongside osteopathy. Use with a sleeping bag for a newborn and it's ideal. His temperature is regulated well and he seems happy and comfortable. I am happily recommending this mattress to friends and family. Thank you sleepcurve.

    Thank you for the review Heather.

    We have recently changed the information on the Cot Bed mattress page to say 'Our Cot Bed Mattress is suitable for babies who are too big to sleep comfortably in a crib or Moses basket' - which is what we should of said all along!
    Great news that Jim is happy and comfortable on the SleepCurve mattress :-)
    And many thanks for recommending our mattresses.

  8. Making big difference! 5 Star Review

    I first heard about the sleep curve mattress from my osteopath who was treating my 5 month old daughter who had a favourite side and no matter what I did she wouldn't move her head to the other way whilst sleeping. I have to say that after a month of my daughter using it I have seen a big difference already and her face has evened out and she sleeps more on her back which she never did before. I now have a few friends who will be buying one!

    Great news :-)
    Thanks for the review Caroline

  9. great matress 5 Star Review

    My husband and i purchased the sleep curve mattress for our 6 month old baby who developed a flat spot at the back of head from around 4 months old. I Had been very concerned and conscious of this and had tried numerous of repositioning techniques, plenty of tummy time, baby wearing and also purchased a pillow, however was unable to use at night due to risk of SIDs. However i had not witnessed an improvement, since i have purchased the sleep curve i have already noticed an improvement and i am so happy that my babies head now seems to be rounding! I can now relax when i put baby to bed at night as i know that for 10-12 hours while he sleeps he is comfortable and the pressure at back of his head is reduced and evenly distributed. As a nurse myself and as a mother i would highly recommended this product, excellent quality and fast delivery!! Thanks sleep curve

  10. Amazingly effective! 5 Star Review

    I bought this mattress for my four month old baby boy who had developed a flattening to the left side of his head which other people had started to notice. He had been a very unsettled baby from birth and had never slept for more than a couple of hours at a time. The first time he slept on this mattress he slept a whole six hours !! He seemed more comfortable, his breathing was calmer and he seemed more relaxed, what's more within days his head flattening started to resolve, after ten days it was visibly improved and after three weeks you could barely see a difference between the two sides! Altogether I have a happier, calmer baby with a perfect head shape, would I recomend this product? Absolutely 100%!
