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.

Comfortable and supportive mattress topper improves sleep quality and reduces pain for many, but common issues include sliding off the mattress and lack of securing straps.

SLIDES EVERYWHERE
While the mattress topper itself is comfortable, the lack of anything to hold it on the mattress is disappointing. It slides everywhere despite a fitted sheet. It moves every time you turn over.

Good quality
Bought this topper for extra firmness, delivered on time, but being folded in box it had developed a kink in mattresse, so every morning have to strip off bed to straighten it out which is a chore for me as I am 80,

No benefit
I have a good quality mattress which is quite firm. I bought the topper in the hope it would be easier on my shoulders and generally more comfortable as I have a chronic back problem. Unfortunately it has not helped. Dormeo have offered to change it for a better quality topper which I’m considering. The topper would also benefit from having corner straps to keep it in position, if you sleep on your own it works itself to one side.

Mattress lifting
The only problem we have is the math lifts a night sleep and little bulges in the middle. It happens on both mattresses but not sure what the problem is..

Brilliant mattress
I bought the Areocell topper for my spare bedroom and it made an uncomfortable bed into a very comfortable bed. I would definitely buy another one

Matress moves
I do find this topper comfortable, however it moves every night and the cover moves also. I have to move it back every day and have rotated the topper every week.

A great purchase
My husband and I both love our Dormeo mattress topper. It’s very comfortable and is definitely helping us to not wake up feeling far too hot in the middle of the night. The best thing about it is that I no longer get disturbed every time he turns over. I know the tv advises claims this is one of the benefits but I didn’t believe it would be so effective until we tried the topper for ourselves. I definitely recommend this product. It’s a very good quality and represents great value for money.

Requires improvement!
Does what it's supposed to, but moves around on the bed, despite being well secured by sheets. A change in the bottom layer would solve this. There is also a tendency for the cover to move around on the memory foam. Requires a redesign. Comfort is fine.

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.

Thank you for using Q&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.
Hi Wally
No, the Dormeo Octasmart Essential Mattress Topper - Single is wipe clean only.
Thanks for using Q&A.

Hi Nan
