About this product

Boost the comfort and support of your existing bed with this mattress topper that relieves pressure while you sleep and keeps you feeling fresh all night. It's fitted to single beds and adds a 5cm layer that moulds to your body, supporting your shoulders, hips and back with breathable foam that allows air to flow freely. The structure is designed to stay cool and comfortable, so you'll wake up refreshed without needing to replace your whole mattress. It's non-allergenic, which makes it suitable for sensitive sleepers, and the wipe-clean cover keeps maintenance simple.

The foam filling uses Octacell technology to provide ergonomic pressure relief across your entire body, while the breathable design prevents heat building up during the night. The fitted style grips mattresses up to 190cm long and 90cm wide, staying secure as you move. The cover is wipe clean, so you can keep it looking fresh with minimal effort. Whether you're upgrading a guest room or adding extra comfort to your own bed, this topper delivers practical support and a cooler night's sleep you'll notice straight away.

Not the dream topper I expected

I bought this topper a few weeks ago as I have Spinal Stenosis and thought this would be more comfortable for sleeping. I have to say I am actually disappointed with it. Firstly it won't keep still on my bed , it slides about on the mattress. I am constantly having to push it back into place, which does not do my back any good. Also I can feel my other mattress through it. It looks.as if it has lots of support on the TV advert, but it is too thin to give support. My sleep hasn't improved at all.anx it definitely hasn't helped with the stenosis. I had high hopes for.this but I am very disappointed.

Overall value for money however disappointed with the fact it has no straps to hold it in place so it's forever moving

Don't buy this mattress topper, it doesn't stay put. There's nothing to keep it attached to the main mattress and it gradually slides of the mattress taking the bedding with it. A complete waste of money.

Exactly what it says on the box, a very comfortable,sleep inducing topper but one little problem, you will need to purchase a non slip cover for your mattress to stop the topper slipping during the night.

Q
Do you sleep direct on topper or do you place a sheet over it?

Question from Tony

Hi Tony,

It’s recommended to place a fitted sheet over the Dormeo Octasmart Essential Mattress Topper. This helps keep the topper clean and in place, ensuring a more comfortable sleep experience.

Hi Nan

The 100 night comfort promise is only available for selected mattresses, not mattress toppers such as the Dormeo Octasmart Essential Mattress Topper - Single. Any free trials will be clearly shown on the webpage at the time.
