The mattress that moves with you.

Because you get the best of both. 2,000 individually pocketed springs give responsive support that follows the shape of your body, while foam and fibre comfort layers ease the pressure on your hips and shoulders.

Unlike foam-only mattresses, the open spring core lets air move through, so you don't sink in or overheat. Unlike traditional open-coil mattresses, every spring works on its own, so it moulds to you rather than pushing back.

Sleeply is medium-firm, the feel that suits the most people:

• Back sleepers get the support to keep their spine naturally aligned.
• Side sleepers get enough give at the shoulders and hips.
• Front sleepers stay level rather than sinking in.

If you share a bed with someone who likes a different feel, medium-firm is the comfortable middle ground.

It's designed not to. The breathable knit cover and open pocket-spring core let heat escape and fresh air circulate through the mattress all night, rather than trapping warmth around you the way solid foam can.

Far less than on an ordinary sprung mattress. Each of the 2,000 springs is wrapped in its own fabric pocket and moves independently, so when one of you turns over, the movement stays on their side of the bed.

Sleeply's springs respond individually to support each part of your body, helping keep your spine in a natural line whether you sleep on your back, side or front. If you have a back condition, it's always worth asking your GP or physiotherapist what's right for you.

Within 2 working days, delivered free to any UK mainland address. Your mattress comes rolled and vacuum-packed in a box, so there's no waiting around for a large van and no awkward manoeuvring.

Easily. Because it arrives rolled in a box, you can carry it up narrow stairs, round tight corners and into loft rooms where a full-size mattress would never fit. Larger sizes are heavy, so it's a two-person lift.

It starts expanding the moment you unwrap it and reaches its full 30 cm depth within 24–48 hours. Unwrap it on your bed frame, open a window, and let it breathe.

Sleeply comes in all five standard UK sizes: Single 3ft (90 × 190 cm), Small Double 4ft (120 × 190 cm), Double 4ft6 (135 × 190 cm), King 5ft (150 × 200 cm) and Super King 6ft (180 × 200 cm). It's 30 cm deep, so choose deep-fitted sheets.

It works on divans and on slatted frames with slats no more than 7 cm apart.

Like most new mattresses, it may have a slight "new" smell when first unwrapped. It's completely normal and fades within a few days, faster with a window open.

We sell directly to you online, with no showroom, no middlemen and no salespeople to pay for, so more of your money goes into the mattress itself. That's how we can offer 2,000 pocket springs and a 3-year guarantee from £129. That's less than 12p a night over the guarantee alone.

Every Sleeply is guaranteed for 3 years against structural and manufacturing faults, including broken or loose springs, failure of the edge support, seams coming apart, and dips deeper than 3 cm.

You have 14 days from delivery to cancel. If your mattress is still in its original sealed packaging, you'll get a full refund less a £20 collection charge. Mattresses that have been unwrapped can't be resold as new, so we reduce the refund to reflect any loss in value. That's why we recommend checking your size before you unwrap. Full returns policy.

Use a mattress protector to keep it fresh, and turn it head-to-foot every 3 months in the first year, then every 6 months, so it wears evenly. Keep it on a firm, flat base.
