The Sleepeezee Wool Supreme combines a silk and wool comfort layer with 2,000 pocket springs, which means you get a soft, cushioned surface over support that responds to your body rather than the whole bed. At 28cm deep with a Belgian damask cover, it feels like a traditional mattress rather than a modern foam one. Sleepeezee is an NBF-approved manufacturer with a Royal Warrant, and the mattress is made in the UK. If you like natural materials and a classic feel, it deserves a place on your shortlist.

Why should you choose this mattress?
The main draw here is the natural filling at a mid-range price. Wool and silk breathe far better than synthetic foams, which means hot sleepers should stay noticeably cooler through the night. The 2,000 pocket springs each move independently, so you get pressure relief where you need it and less disturbance from a partner shifting about. The medium firmness suits most sleepers, although anyone who prefers a very firm, unyielding surface may find the cushioned top a little soft for their taste. MattressNextDay states a 10-year guarantee and free next day delivery, with the mattress arriving flat rather than rolled. It comes in six sizes, including EU Double and EU King.
Key features & layer details
Silk
A light, soft silk layer sits at the top, which means the surface feels gentle and luxurious the moment you lie down. It is a comfort layer rather than a support one, so it shapes the initial feel of the mattress.
Wool
Beneath the silk, wool adds a soft, cushioned feel and helps regulate temperature naturally. It suits people who want a traditional, natural mattress rather than a synthetic one.
2000 Pocket Springs
Each of the 2,000 springs sits in its own fabric pocket and works independently, which means support adapts to your body shape and pressure points. This also helps limit motion transfer if you share the bed.

Best suited for?
Warm sleepers
Wool and silk breathe far better than synthetic foams, which means you should stay noticeably cooler through the night.
Couples
Each of the 2,000 pocket springs works independently, which means less disturbance when your partner shifts about during the night.
Side sleepers
The soft silk and wool comfort layers cushion the shoulders and hips, while the pocket springs adapt to your body shape underneath.
Eco-conscious buyers
Natural silk and wool fillings give you a traditional mattress without synthetic foam, and it is made in the UK.
European bed frames
Six sizes are available, including EU Double and EU King, so it fits continental frames without needing a special order.
This is not the mattress for you if you want a firm feel; the medium tension with soft silk and wool layers will feel too forgiving for some back sleepers who like a solid surface. It arrives flat rather than rolled, which can make manoeuvring it up tight staircases trickier. No trial period is mentioned on the retailer's page.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
Is the Sleepeezee Wool Supreme mattress firm or soft?
It is a medium firmness. The silk and wool top layers give a soft, cushioned surface feel, while the 2,000 pocket springs underneath provide the support. It suits most sleepers, although those who want a very firm mattress may find it a little too plush.
Does the Sleepeezee Wool Supreme come with a guarantee?
MattressNextDay's listing states a 10-year guarantee. Because this term appears on a retailer's page rather than Sleepeezee's own site, it is best to confirm the guarantee with whichever retailer you buy from.
How deep is the Sleepeezee Wool Supreme mattress?
It is 28cm deep, a generous depth that should work with standard fitted sheets. It arrives flat rather than rolled, so measure any tight corners or stairways before delivery.
What sizes does the Sleepeezee Wool Supreme come in?
Six sizes are available: UK Single, UK Double, UK King, UK Super King, plus EU Double and EU King. The EU options are handy if you have a continental bed frame, as many brands skip these sizes.
Is the Sleepeezee Wool Supreme good for hot sleepers?
Yes, it should suit you well. Wool and silk are naturally breathable fillings that wick moisture and regulate temperature, and the pocket sprung core allows air to move through the mattress more freely than solid foam would.
