The Tuft & Springs Ortho Tranquility 5000 uses 5,000 individually pocketed springs, which means the support adapts to your body rather than moving as one unit, and it's topped with wool, cotton, cashmere and silk for a breathable sleep surface. At 32cm deep it's a substantial mattress, so check your fitted sheets will stretch. The firm feel suits back and front sleepers who want a supportive base, although lightweight side sleepers may find it a little too unyielding at the shoulder and hip.

Why should you choose this mattress?
If you sleep hot, the natural fillings here work in your favour: sustainably sourced British wool, cotton, cashmere and silk all wick moisture, which means less of that clammy feeling foam-heavy mattresses can give. The 5,000 pocket springs respond to each sleeper independently, useful if you share a bed with someone who tosses and turns. It's made by an NBF-approved manufacturer and is hypoallergenic, a reassurance if dust mites trouble you. Yes, the starting price is a real outlay for a single, but natural fillings and a high spring count usually cost more than this. The brand backs it with a 5-year guarantee and free next day delivery. It comes in four UK sizes, from Single to Super King.
Key features & layer details
Cover
A Belgian Damask viscose sleep surface that feels silky and soft to the touch. It's highly breathable, which helps keep the sleeping environment fresher through the night.
Comfort fillings
A blend of sustainably sourced British wool, cotton, cashmere and silk. These natural fibres breathe and wick moisture, which means you're less likely to overheat.
Support system
5,000 individually pocketed springs sit beneath the fillings. Each spring moves on its own, so the mattress contours to your body and responds where you need support.

Best suited for?
Back sleepers
The firm feel gives a supportive base, while the 5,000 individually pocketed springs adapt to your body so your back stays well supported through the night.
Front sleepers
A firm surface keeps your hips from sinking too far, and the pocketed springs respond where you need support, which suits lying face down.
Warm sleepers
Wool, cotton, cashmere and silk all wick moisture and breathe, which means you are less likely to overheat or feel clammy during the night.
Couples
Each of the 5,000 pocket springs moves independently, so the mattress responds to each sleeper separately, which helps if your partner tosses and turns.
Allergy sufferers
The mattress is hypoallergenic and filled with natural fibres, which gives some reassurance if dust mites bother you.
This is a firm mattress, so lightweight side sleepers may find it presses uncomfortably at the shoulder and hip rather than letting them sink in. If you prefer a plush, cushioned feel, or the slow hug of memory foam, this sprung, natural-filled design will feel too taut for you.
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 and springs ortho tranquility 5000?
Tuft & Springs describes it as firm. In practice that means a supportive, taut feel that suits back and front sleepers, and heavier bodies generally. Lightweight side sleepers may find it a little too firm for comfortable pressure relief at the shoulders and hips.
How many springs does the ortho tranquility 5000 have?
It has 5,000 individually pocketed springs. Because each spring is sewn into its own fabric pocket, they compress independently, which means the mattress contours to your shape and limits motion transfer when a partner moves during the night.
Does the ortho tranquility 5000 come with a guarantee?
Yes, Tuft & Springs offers a 5-year guarantee on this mattress. Delivery is free and next day, which is handy if your old mattress has given up suddenly.
Is the ortho tranquility 5000 good for allergies?
It's listed as hypoallergenic, and the natural fillings, including wool, are breathable and moisture-wicking, conditions dust mites tend to dislike. If you have severe allergies, it's still sensible to pair it with a washable mattress protector.
What sizes does the tuft and springs ortho tranquility 5000 come in?
It's available in UK Single, Double, King and Super King. It's 32cm deep, so deep fitted sheets are a sensible buy alongside it.
