At 32cm deep, the Sleepeezee Witham pairs 2,400 pocket springs in the king size with cooling Staycool gel and a bamboo cover, which means you get proper firm support without the hot, sticky feel that often comes with gel and foam layers. It sits at the pricier end, although the depth and spec go some way to justifying that. It suits people who want firm support with a softer surface feel.

Why should you choose this mattress?
The main appeal is the combination of firm tension underneath and a cloud-like pillow top above, which means the enhanced support does the structural work while the surface stays forgiving on shoulders and hips. Hot sleepers are well served here: the bamboo cover wicks away moisture and dual layers of Staycool gel help regulate temperature through the night. The reinforced side support border resists dipping at the edges, useful if you sit on the bed to dress or sleep close to the side. It comes in UK Single through Super King, with a 10-year guarantee stated on the Feather & Black listing. It is a significant spend, but the 32cm build feels made to last.
Key features & layer details
Bamboo cover
An ultra-soft knitted bamboo cover wicks away moisture, which means less clamminess on warm nights. It also has a naturally antibacterial finish to help prevent odours forming.
Pillow top
A cloud-like pillow top adds a plush, indulgent surface feel over the firm core. It includes a layer of cooling gel for soothing relief as you sleep.
Staycool gel
Dual layers of Staycool gel regulate your temperature through the night. They also give pressure-sensitive support, adapting to where your body pushes in most.
Pocket springs
2,400 pocket springs in the king size move independently to cushion your body, which means less disturbance when a partner shifts. Highly adaptive nano pocket springs add a finer layer of support.
Side support border
An enhanced side support border creates a durable edge around the mattress. This helps prevent dipping or sagging where you sit or sleep near the side.

Best suited for?
Warm sleepers
The bamboo cover wicks away moisture and dual layers of Staycool gel help regulate temperature, which means less clamminess on warm nights.
Couples
Pocket springs move independently to cushion each body, which means you feel less disturbance when your partner shifts, while the reinforced edge gives you more usable space.
Back sleepers
Firm tension underneath keeps the spine supported, while the cloud-like pillow top adds a forgiving surface feel that stops the mattress feeling harsh.
Heavier sleepers
The 32cm build, firm tension and 2,400 pocket springs in the king size give enhanced support that should resist sinking and feel durable.
If you prefer a soft or medium feel, this firm tension will likely be too solid, particularly for lightweight side sleepers who may not sink far enough into the pillow top for proper pressure relief. Budget shoppers should also look elsewhere, as even the single starts at a premium price.
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 Witham mattress firm or soft?
It has a firm tension for enhanced support, so it suits back and front sleepers and those who like a solid base. The pillow top softens the surface feel a little, but lighter side sleepers may still find it slightly too firm.

Does the Sleepeezee Witham come with a trial or guarantee?
Feather & Black offers a 100-night trial, and a 10-year guarantee is stated on its page. These are the retailer's terms, so check what applies wherever you buy.
Is the Sleepeezee Witham good for hot sleepers?
Yes, cooling is one of its strengths. The bamboo cover wicks away moisture, the pillow top includes cooling gel, and dual layers of Staycool gel help regulate your temperature through the night.
How much does the Sleepeezee Witham mattress cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. It comes in UK Single, Double, King and Super King. It is a premium price, though the 32cm depth and Kent-handcrafted build help explain it.
