The Nectar Memory Foam Mattress is 25cm deep and built from three layers of CertiPUR certified foam beneath a cooling cover, which means you get the classic contouring memory foam hug without quite as much heat retention as older foam designs. Nectar backs it with a 365-night trial, longer than most brands offer. If you want a foam mattress that feels supportive rather than sinky, this is a sensible place to start, although if you prefer a springy, traditional feel, you may want a hybrid instead.

Assessed from Nectar's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw here is the balance of contouring and reassurance. The pressure-relieving memory foam adapts to your shape, which means less pressure on hips and shoulders if you sleep on your side, while the 7-zone base gives firmer support where your body is heaviest. Hot sleepers get some genuine help too: the cover carries MTick certification for menopause-friendly cooling, and the open-cell foam encourages airflow. Then there's the safety net. A 365-night trial gives you a full year to decide, and Nectar's Forever Warranty has no expiration date, which is unusually generous. It's a memory foam feel through and through, so you'll sleep slightly in the mattress rather than on it.

Side sleepers
The pressure-relieving memory foam adapts to your shape, which means less pressure on your hips and shoulders when you lie on your side.
Warm sleepers
A cooling cover and open-cell foam that encourages airflow help the mattress release heat, so it should feel less stuffy than older memory foam designs.
Back sleepers
The 7-zone support base gives firmer support under the heaviest parts of your body, which means a supported, reassuring feel while you lie flat.
Eco-conscious buyers
The foam layers are CertiPUR certified, which gives some reassurance about the foam itself, though the build is all synthetic rather than natural materials.
If you love the springy, pushed-back feel of a traditional pocket sprung mattress, the contouring foam here will feel too enveloping. If you prefer a very soft, sink-in surface, you may also find the medium-firm feel a little solid, and strict natural-materials shoppers should look elsewhere, as this is an all-synthetic foam build.
Save with the previous model
Some retailers still sell the earlier version of this mattress. These are the sizes where it costs less than the current model's best price.

Is the Nectar Memory Foam Mattress firm or soft?
Nectar describes it as a medium-firm feel, 6.5 out of 10. That suits most back and stomach sleepers, and the contouring memory foam softens the surface enough for many side sleepers too, although lightweight side sleepers may find it slightly too firm.
Does the Nectar mattress sleep hot?
It's designed to run cooler than typical memory foam. The cover wicks heat away, the open-cell foam encourages breathability, and it holds MTick certification for menopause-friendly cooling and support. Foam still retains more warmth than springs, so very hot sleepers should factor that in.
How long is the Nectar mattress trial?
Nectar offers a 365-night trial, so you have a full year to decide at home. The brand also offers its Forever Warranty, a guarantee with no expiration date rather than a fixed year term.
How thick is the Nectar Memory Foam Mattress?
It's 25cm deep, made up of three layers of CertiPUR certified foam plus the cover and a non-slip base layer. Standard fitted sheets should fit without trouble.
What sizes does the Nectar Memory Foam Mattress come in?
It's available in UK Single, Small Double, Double, King and Super King. Delivery is free named day shipping.
