Assessed from the specification published by Feather & Black, captured September 2026, and from regular price comparison across our UK retail partners.
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 & what's inside
- 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.

Who's it NOT for?
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 £1,099.
Sleepeezee Witham Mattress
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.
How many springs does the Sleepeezee Witham have?
The king size contains 2,400 pocket springs, which move independently to cushion your body and reduce partner disturbance. These are supplemented by highly adaptive nano pocket springs for enhanced support.
Does the Sleepeezee Witham come with a trial or guarantee?
Feather & Black, the retailer listing this mattress, 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?
Prices range from £1,099 to £2,299 depending on size, with UK Single, Double, King and Super King available. It is a premium price, though the 32cm depth and Kent-handcrafted build help explain it.
