About this product
Add extra comfort to your mattress with this topper that layers supportive Octacell foam across a 5cm depth. It's designed to fit king size beds and features a breathable foam structure that allows air to circulate freely. The fitted design grips your mattress securely without shifting about, and the non-allergenic material is suitable for sensitive sleepers. The Octacell foam construction is engineered to distribute weight evenly across the surface, and the easy-care cover wipes clean with minimal effort.
The topper sits neatly on your existing mattress and adds a cushioning layer that works with your current setup. The breathable structure keeps the topper fresh between cleans, and the wipe-clean cover means maintenance stays straightforward. It's a practical addition if you're looking to refresh an older mattress or adjust the firmness of your bed. Whether you're upgrading your own bedroom or preparing a guest room, this topper provides an accessible way to adjust your sleeping surface without replacing your entire mattress.

Customers Say
Comfortable and supportive mattress topper improving sleep quality, but many users report it slides on the bed due to lack of securing straps and is thinner than expected.

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.

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

Rubbish
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.

Very nice,but.
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.

Thank you for using Q&A.
You do not flip this topper for to decide its firmness. They come in two different styles
Firm topper or plush topper. Argos obviously dont know this.
Hi There,
Dormeo Octasmart Essential Mattress Topper - Double
Having checked I can see the choice between two comfy feels is yours. The Aerocell® topper for firmer support, which is perfect for using on sofa beds or directly on the floor, or the plush comfort of the Memory topper to add sumptuous luxury to your existing mattress. You can simply flip the topper depending on what firmness you require.
Thanks for using Q and A.

Hi Malaga1,
Dormeo Octasmart Essential Mattress Topper - Double 313/4368 This item should not be used with an electric blanket as this can cause the foam to become misshapen which will void the warranty.
Thank you for using Q&A
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.
Thank you for using Q&A
I place a mattress protector and a sheet over
It doesnt stay in place, it moves and hangs over the edge throughout the night.
Hi there,
Regarding the Dormeo Octasmart Essential Mattress Topper - Double. The Topper is laid flat on the bed and then when you use a fitted sheet it will stay in place with this accompanied with it.
Thanks for using Q&A.
