Why should you choose this mattress?
This mattress suits sleepers who want a supportive, medium firm base without a hard surface feel. The pillow top and memory foam give you gentle, contouring comfort on top, which means pressure relief at the shoulders and hips, while the pocket springs beneath keep your spine reasonably well aligned. It's hypoallergenic and vegan friendly, and it's made in the UK by an NBF-approved manufacturer, which offers some reassurance about materials and build quality. The breathable knitted cover helps with temperature, although memory foam does hold a little more warmth than an all-spring design. Buying through MattressNextDay, you also get free next day delivery listed.
Key features & layer details
Pillow Top
An additional layer of plush fillings sewn onto the top, which means a softer initial feel when you lie down. You get cushioned comfort without changing the medium firm support underneath.
Knitted Cover
A soft knitted cover that's breathable, helping to keep you at an even temperature through the night.
Body-Contouring Memory Foam
Super-soft memory foam that adapts to your shape, easing pressure on your joints. Its slow response minimises bounce, so you're less likely to feel a partner moving.
Soft Polyester Comfort Layers
Soft polyester layers that add cushioning without compromising the medium firm feel.
High-Density Polyester Support Layer
A denser polyester layer beneath the comfort fillings, which helps the mattress hold its structure and last longer.
4000 Pocket Spring System
1000 traditional pocket springs combined with 3000 mini comfort springs. Each spring moves independently, which means support that follows your body rather than pushing back as one flat surface.

Best suited for?
Side sleepers
The pillow top and body-contouring memory foam cushion the shoulders and hips, so your body can sink in gently while the springs underneath keep support steady.
Couples
Memory foam with a slow response minimises bounce, so you're less likely to feel a partner moving, and each pocket spring works independently.
Allergy sufferers
Being hypoallergenic is a listed feature of this mattress, which makes it a sensible choice if you want bedding that suits sensitive sleepers.
Eco-conscious buyers
This hybrid is vegan friendly and made in the UK by an NBF-approved manufacturer, which gives some reassurance about materials and build quality.
Back sleepers
Medium firm support from 4000 pocket springs follows the shape of your body, which helps keep your spine reasonably well aligned without a hard surface feel.
If you prefer a genuinely soft mattress, the medium firm support here may feel too solid despite the pillow top. If you prefer a springy, bouncy surface, you may also find the slow-response memory foam a little too still. And note the pillow top means the mattress can't be flipped, only rotated.
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.

It has 4000 springs in total: 1000 traditional pocket springs providing the main support, plus 3000 mini comfort springs that fine-tune how the surface responds to your body.
Does the Sleepeezee Memory 4000 come with a guarantee?
Yes, it comes with a 10-year Sleepeezee manufacturer guarantee, as stated on the MattressNextDay listing. There's no sleep trial mentioned on that page, so check returns terms with your retailer before buying.

It's 30cm deep, which is on the taller side thanks to the pillow top. You may want deeper fitted sheets to get a proper fit.
