Assessed from Tuft & Springs's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw is the combination of a plush pillow top and up to 5,000 pocket springs. The springs work independently, which means support goes where your body presses down, at your hips and shoulders, rather than the whole surface sinking together. The wool, cotton and cashmere fillings give a cushioned, slightly luxurious surface feel and handle temperature better than synthetic foams tend to. Yes, £899 as a starting price is a real spend, but the natural materials and the depth of the build go some way to justifying it. The 5-year guarantee is shorter than some brands offer, so weigh that against the spec if longevity is your main concern.
Key Features & what's inside
- Pillow Top. A plush stitched-in pillow top filled with wool, cotton and cashmere, which means a soft, cushioned surface without needing a separate topper. The natural fibres also help regulate temperature, useful if you tend to sleep warm.
- Pocket Springs. Up to 5,000 pocket springs that move independently of one another, which means support is targeted to your pressure points rather than spread evenly. It also helps limit motion transfer, so a restless partner is less likely to wake you.

Who's it NOT for?
If you prefer a firm mattress, the medium feel and plush pillow top will likely feel too soft. The pillow top is stitched in, so it can't be flipped or replaced. And at 38cm deep, you'll need deep fitted sheets, a small but genuine annoyance if your current bedding is standard depth.

How firm is the Tuft & Springs Serenity 5000?
The brand describes it as medium. Combined with the plush pillow top, expect a cushioned surface feel over supportive pocket springs, which suits most sleepers, although lightweight side sleepers should find it forgiving while dedicated firm-mattress fans may find it a little soft.
How deep is the Serenity 5000 mattress?
It's 38cm deep, which gives it a tall, hotel-style profile. You'll need deep fitted sheets to get a proper fit.
What is the Serenity 5000 made of?
The fillings include sustainably sourced British wool, cotton and cashmere in the pillow top, over up to 5,000 pocket springs, all finished with a Belgian damask viscose sleep surface. It's made by an NBF-approved manufacturer and meets the BS7177: 2008 low hazard fire resistance standard.
Does the Tuft & Springs Serenity 5000 come with a guarantee?
Yes, it comes with a 5-year guarantee. That's shorter than some brands offer, so factor it in if long-term cover matters to you.
What sizes does the Serenity 5000 come in?
It's available in UK Single, Double, King and Super King, with prices ranging from £899 to £1,159 depending on the size you choose. Delivery is free and next day.
