Wake up and mean it. The Emma Original is Emma's best-selling mattress, five layers built to give your body what it needs, in the right order, every night. The difference starts with MemoryAdapt foam. It molds to your shape, distributing weight evenly across your shoulders, hips and lower back so you're genuinely supported rather than just lying on top. Above it, Airgocell® foam releases humidity and keeps air moving. Below, SupportBase creates a smooth handoff to the spring core without any sinking feeling. At the heart of it is a 5-zone InfinitySpring pocket spring core. Taller-than-standard springs run edge to edge, five independent zones responding to your head, shoulders, back, hips and legs separately. More air moves through, less heat builds up. And if you share a bed, those same springs absorb every toss and turn before it reaches the other side. The UltraDry cover is soft, fully removable and machine washable at 40°C. Moisture-wicking properties survive the wash. UKFR certified. 25 cm tall. Try it for 100 nights. Not right for you? Returns are handled through Wayfair. The 10-year guarantee covers all foam and spring layers. Product of the Year, Sleep Awards 2024 by Expert Reviews. The Telegraph Recommended. T3 Platinum Award

A good night's sleep starts with the right support. If you're tired of waking up with a sore back or getting disturbed every time your partner moves, this mattress is exactly what you've been looking for. It's built the way a proper mattress should be — individual pocket springs, a generous 27cm profile, and a soft-to-touch knitted cover that breathes. No gimmicks. Just solid, comfortable support that works night after night. Here's the thing about cheap mattresses — they feel okay in the showroom, but six months later the springs have started to sag and you're waking up with that familiar ache in your lower back. This mattress is built differently. The pocket springs are individually housed, so they don't interlink and pull on each other. Every spring moves independently, cradling your body's natural curves. The 27cm thickness gives it that premium feel without the premium price tag. And because it comes vacuum-packed and rolled, you can get it up the stairs, into the bedroom, and set up in minutes — no awkward manoeuvring through narrow hallways. Just unbox, let it breathe for a few hours, and you're ready to sleep. Please note: This mattress is vacuum-packed and rolled for delivery. Allow 24–72 hours for the mattress to fully expand to its original shape and height after unpacking. Expansion time may vary depending on room temperature. This product is a mattress only. Mattress protector, bed frame, and bedding are not included.
