Dormeo Octasmart mattress - anyone got one?

[Lobelia76]

We need a new mattress and I’m driving myself crazy with reviews. Does anyone have one of these? It’s the Octasmart Plus Memory Foam mattress I’m looking at specifically, down to £500 from £1000

We spent ages looking a couple of months ago. Ended up buying the simba hybrid ..... best decision ever!

Sometimes I’d love to go back to the old days when you just bought something without hundreds of reviews to pick through! Lots of reviews say the Simba makes you too hot?

Not been too hot yet .... although it's not summer?!

We do, I love it, DH not as keen. I sleep on my side and it has really improved my sleep. DH says he gets too hot

And we’ve had ours over a year

I have a Dormeo............not that model, we have had our for a few years and it was a Which best buy and a bargain compared to some of the bigger brands.
We love ours, I sleep on my side and it is wonderful. I would suggest taking out a trial subscription to Which and reading their latest mattress reviews.

A complete warning to anyone considering buying from Dormeo UK. They heavily advertise a "risk-free" trial period, but it turns out to be nothing more than empty marketing tricks when you actually need help.
I purchased a mattress that was delivered on July 3, 2026. Shortly after unboxing it, the mattress started emitting a strong, overpowering chemical odor. Dormeo's customer service acknowledged in their emails that this is known as "off-gassing." However, despite the unbearable smell making the room unpleasant and concerning to sleep in, they flatly refused to offer any replacement or assistance.
After further review and escalations, their senior customer service and B2B operations team simply hid behind corporate policies, claiming it is a "normal characteristic of memory foam products" and washing their hands of the issue. To top it all off, instead of offering a resolution or a product exchange under their promised trial, they told me to contact my "local council" for escalation routes.
This is a disgraceful way to treat customers. Selling a product with a terrible chemical odor and then refusing to exchange it—while ignoring their so-called guarantee—is unacceptable. Save your money and your peace of mind, and shop elsewhere.
