At 38cm deep, the Tuft & Springs Serenity 5000 has the tall, hotel-style look, and the natural fibres help with breathability, which means less of that clammy feeling on warmer nights. It's available from UK Single through to Super King. It comes from an NBF-approved manufacturer with a 5-year guarantee and free next day delivery. It suits most sleepers who like a softer surface over firm support, although anyone wanting a truly firm feel should look elsewhere.

Why should you choose this mattress?
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, the 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 & layer details
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.

Best suited for?
Warm sleepers
Wool, cotton and cashmere fillings help regulate temperature, which means less of that clammy feeling on warmer nights than synthetic foams tend to give.
Couples
Up to 5,000 pocket springs move independently and help limit motion transfer, so a restless partner is less likely to wake you.
Side sleepers
The plush pillow top gives a soft, cushioned surface, while independent springs let support follow your hips and shoulders instead of the whole mattress sinking together.
Combination sleepers
Independently moving pocket springs direct support to wherever your body presses down, which suits changing position through the night on a softer, cushioned surface.
Eco-conscious buyers
Natural wool, cotton and cashmere fillings in the pillow top give a luxurious feel and manage temperature better than synthetic foams usually do.
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.
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
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, and if you prefer sleeping on a firm mattress, you 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. Delivery is free and next day.
