The Sleepeezee Natural 4000 uses latex that contours to your body, which means pressure relief that responds quickly rather than the slow sink of memory foam, while the springs work independently to limit motion transfer. It's rated Medium Firm, so it suits most back and combination sleepers, although lightweight side sleepers may find it slightly too firm. It comes in four UK sizes, and Sleepeezee is an NBF-approved manufacturer making it in the UK.

Why should you choose this mattress?
If you like the idea of natural materials but still want proper spring support, this mattress makes a strong case. The Talalay latex is hypoallergenic and highly breathable, and a blend of British wool and silk helps regulate temperature, keeping you cooler in summer and warmer in winter. That makes it a sensible pick for hot sleepers who overheat on all-foam mattresses. The Medium Firm feel with a plush pillow top gives you a softer surface over firmer support underneath, which many back sleepers find comfortable. It's a real investment, but a 30cm build with natural latex and a Sleepeezee 10-year guarantee goes some way to justifying it.
Key features & layer details
Pillow Top
A plush layer of fillings sits on top of the mattress, which means a softer initial feel before you reach the firmer support below. It gives the surface that cushioned, sink-in-slightly quality without needing a separate topper.
Belgian Damask Viscose Sleep Surface
A silky, highly breathable cover that helps keep the sleep surface feeling fresher. It's the layer your skin is closest to, so the softness here matters more than you might expect.
Natural Talalay Latex
100% natural Talalay latex contours to your body, which means pressure relief with a responsive, slightly buoyant feel rather than a slow sink. It's also hypoallergenic and highly breathable, a genuine plus for allergy sufferers and hot sleepers.
Natural Latex Layer
Two further layers of natural latex cushion key areas such as the shoulders, hips and lower back. They provide responsive pressure relief without excessive sink, so you stay supported rather than swallowed.
Sustainably Sourced British Wool & Silk
A naturally soft, lightweight blend of British wool and silk that offers excellent insulation. In practice that means it helps keep you cool in summer and warm in winter, evening out temperature swings through the year.
Polycotton Comfort Layers
Polyester and polycotton fibre layers add cushioning with good recovery and rebound. This helps the comfort layers keep their shape over time rather than compressing into dips.
High-Density Polyester Support Layer
A high-density polyester layer beneath the comfort fillings helps maintain the mattress's structure. Think of it as scaffolding that protects the softer layers above and supports long-term durability.
4000 Pocket Springs
A 4000 pocket spring system combines 1000 traditional pocket springs with 3000 mini comfort springs, each responding independently to your movements. For couples, that means less disturbance when one of you shifts or gets up in the night.

Best suited for?
Back sleepers
The Medium Firm feel pairs a plush pillow top with firmer support underneath, which means a softer surface that still keeps your back comfortably held.
Combination sleepers
Responsive latex gives a slightly buoyant feel rather than a slow sink, which means changing position through the night takes little effort.
Couples
The 4000 pocket springs work independently, which means less disturbance when one of you shifts or gets up in the night.
Warm sleepers
Breathable Talalay latex and a blend of British wool and silk help even out temperature, keeping you cooler in summer and warmer in winter.
Allergy sufferers
The natural Talalay latex layer is hypoallergenic and highly breathable, which makes it a sensible choice if you want a more natural sleep surface.
This is a Medium Firm mattress, so lightweight side sleepers may find it a little too firm through the shoulders despite the pillow top. Anyone wanting a strictly synthetic-free build should note it includes polyester and polycotton layers alongside the natural latex and wool. Budget shoppers may also find the starting price a stretch.
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
How firm is the Sleepeezee Natural 4000 Pocket Latex Ortho mattress?
It's rated Medium Firm. The plush pillow top and latex layers soften the surface feel, while the pocket spring system underneath keeps things supportive. That combination tends to suit back sleepers and heavier side sleepers, although lighter side sleepers may find it slightly firm.
How many springs does the Sleepeezee Natural 4000 have?
It has a 4000 pocket spring system, made up of 1000 traditional pocket springs and 3000 mini comfort springs. Each spring moves independently, which means the mattress responds to your body shape and limits the ripple effect when a partner moves.
Does the Sleepeezee Natural 4000 come with a guarantee?
Yes. The mattressnextday.co.uk listing states a Sleepeezee 10-year guarantee. Terms can vary between retailers, so it's sensible to confirm the guarantee details at the point of purchase wherever you buy.
Is the Sleepeezee Natural 4000 good for hot sleepers?
It should be one of the better options. Talalay latex is highly breathable, and the British wool and silk blend insulates naturally, helping keep you cooler in summer. If you regularly overheat on memory foam, this construction is a sensible switch.
What sizes is the Sleepeezee Natural 4000 available in?
It comes in UK Single, Double, King and Super King. The mattress is 30cm deep, so check that your fitted sheets can accommodate a deeper build.
