"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.

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. Recommended 4 Star Review

    Found mattress worked really well for my son's reflux and defiantly helped shape his head. However found cause he is colic he wasn't able to pass wind easily. I would recommend if your child has reflux or want a round head shape.

  2. Comfort Miracle 5 Star Review

    Firstly, what excellent customer service delivery by sleep curve - Unfortunately, Fedex delivered the product but, due to no notification other than quoting it had been shipped, we were not ready or available for accepting it. Consequently, they sent it to their warehouse - returned to the supplier and the knock on was our daughters baby had to further wait for this to be delivered! However, on contacting sleep curve, (Kath McGrouther*) they dispatched a new product with express delivery and we got it the following day- brilliant. Although, only had it a week, the three month baby who has a flat head condition and reflux has since been sleeping throughout the night, with breathing being 100% better and now we have a more happier baby & mother. Simply, a comfort miracle - sincere thanks to Sleep curve and staff*. Outstanding

  4. Best money I ever spent! 5 Star Review

    I decided to buy the sleep curve crib mattress when my baby was 5 weeks old. I had noticed flattening at the right side of his head which seemed to be becoming more severe with each passing day. He constantly lay on the right side of his head when sleeping , no matter how many times I adjusted his position. I had asked my health visitor and neonatal consultant for advice and both had very little to offer apart from what I already knew about encouraging tummy time. Something which I had done from birth anyway. I am so glad I decided to try the sleep curve mattress. From the first night of using the mattress I noticed that he was able to sleep in a more neutral position and move his head to either side. As the weeks went on I noticed that the flattening ,which had been severe was becoming less and less noticeable . I was so impressed I also purchased the Moses basket mattress for his daytime naps. He still has some flattening but it is minimal. These mattresses really helped in our case and I cannot recommend them highly enough.

  5. My boy sleeps perfectly on this mattress 5 Star Review

    I recently purchased the SleepCurve mattress for my little man and I'm so happy I have got it, he sleeps perfectly on it and looks really comfortable! The curve in the mattress helped him stay in one place while he slept which is what I’m putting his sleeping all through the night down to. But he's now started crawling so he doesn't stay in one place anymore! I would highly recommend this to any parent. I'm definitely going to buy the whole set as he gets bigger!! A+++ mattress. Thankyou SleepCurve
