Assessed from Sleepeezee'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 double depth graphite memory foam layer, which draws heat away from your body. If you like the sink-in feel of memory foam but usually sleep warm, that matters. Beneath it sit 2,500 mini comfort springs and 2,000 traditional pocketed springs with full foam encapsulation, so the edges stay usable and support adjusts to each sleeper independently, helpful if you share the bed with someone heavier or lighter than you. Sleepeezee describes it as medium-firm, which suits most back and front sleepers, although lightweight side sleepers may find it slightly too firm at the shoulder. Yes, it's an investment at £764 upwards, but the spring count and layered build justify the spend.
Key Features & what's inside
- Soft knitted cover. A soft knitted cover forms the sleep surface. It gives a gentle, slightly cushioned first touch.
- Soft polyester comfort layer. A soft polyester comfort layer sits just beneath the cover, which means immediate surface softness before you reach the firmer materials below.
- High density polyester support layer. A high density polyester layer adds a firmer transition. It stops you sinking straight through to the foam and springs.
- Double depth Graphite memory foam. A double depth layer of graphite memory foam that draws heat away from your body. You get pressure relief around hips and shoulders with less of the warmth ordinary memory foam can trap.
- 2500 mini comfort springs. A layer of 2,500 mini comfort springs adds responsive, fine-tuned cushioning. These smaller springs react to smaller movements, so the surface feels adaptive rather than flat.
- 2000 traditional pocketed springs. The base is 2,000 traditional pocketed springs with full foam encapsulation. Each spring moves independently to reduce partner disturbance, and the encapsulated edge means you can use the full width of the bed.

Who's it NOT for?
If you dislike the slow, cradling feel of memory foam and prefer a springy, on-top-of-the-bed sensation, this probably isn't for you. Lightweight side sleepers may also find the medium-firm feel a little unforgiving at the shoulder. And it's non-turn, so it can't be flipped to refresh the feel.

Is the Sleepeezee Memory Ultimate 4500 firm or soft?
Sleepeezee describes it as medium-firm. In practice that means supportive underneath with a cushioned surface from the memory foam and comfort layers, a feel that suits most back and front sleepers, though very light side sleepers may want something softer.
Does the Sleepeezee Memory Ultimate 4500 sleep hot?
It uses graphite memory foam, which is designed to draw heat away from your body. That makes it a better bet for warm sleepers than standard memory foam, although memory foam of any kind tends to feel warmer than a purely sprung mattress.
Do you need to flip the Sleepeezee Memory Ultimate 4500?
No. It's a non-turn design, so you never flip it. Rotating it from head to toe occasionally is still a sensible habit to even out wear.
How many springs does the Sleepeezee Memory Ultimate 4500 have?
It has 4,500 springs in total: 2,500 mini comfort springs near the surface for responsive cushioning, and 2,000 traditional pocketed springs in the base with full foam encapsulation for support and stable edges.
What guarantee comes with the Sleepeezee Memory Ultimate 4500?
