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.

Who's it NOT for?
If you love the springy, pushed-back feel of a traditional pocket sprung mattress, the contouring foam here will feel too enveloping. Fans of a very soft, sink-in surface 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.

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, with prices from £449 and a wider range of £199 to £649 across sizes and retailers. Delivery is free named day shipping.
