Layer Details
Cover
A knit fabric cover with a smooth quilted surface. It gives a soft first touch before you reach the comfort layers beneath.
Memory foam
MemorySense foam that moulds to your body for targeted comfort and pressure relief. In practice this means less pressure on your hips and shoulders, especially if you sleep on your side.
Spring system
Sealy's PostureTech spring system distributes your weight evenly and provides zoned support. That helps keep your spine aligned and stops heavier areas sinking too deeply.

Key benefits
- A shared bed that fits the room: At 135cm wide, the UK double leaves space for wardrobes and drawers in rooms where a UK king would crowd everything else out.
- 67.5cm each for two sharing: Two people get 67.5cm each, which pairs sensibly with the Claremont's MemorySense foam because the contouring settles each sleeper into their own side.
- Modest room requirement: We suggest at least 2.6m x 2.8m for a UK double, achievable in most second bedrooms and older terraces alike.
- Bedside tables on both sides: In a typical UK bedroom the double's footprint usually still allows a table each side, something a wider size often rules out.
- Easy to dress: Double sheets and duvets are sold everywhere at every price, useful if you're furnishing a whole home and spreading the budget thinly.
This size suits you if...
You share the bed every night in a room of typical UK proportions and want the Claremont's medium, cushioned feel without the footprint of a UK king. It also suits a guest room that hosts visiting couples, or a solo sleeper who likes room to spread out, perhaps with a dog or cat that claims a corner most nights.
Consider another size if...
You and your partner are both broad-shouldered or restless, since 67.5cm each can feel snug on contouring memory foam. We'd recommend the UK king instead, which is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m for it.

FAQ's
Is the Sealy Claremont UK double big enough for a couple?
For most couples, yes. At 135 x 190cm you get 67.5cm each, and the MemorySense foam limits how much you feel a partner turning over. That said, if either of you is tall, broad or a restless sleeper, the UK king's extra 15cm of width and 10cm of length is a meaningful upgrade.
What size room do I need for the Sealy Claremont double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves enough clearance to walk round the bed and open drawers, and in most rooms you'll still fit bedside tables on both sides. This guidance is ours, based on the double's 135 x 190cm footprint.
Should I buy the Sealy Claremont in a double or a king?
Choose the UK double if your room is around the typical British size or you want the bed to leave space for other furniture. Choose the UK king if you both like room to sprawl and can allow at least 2.7m x 2.9m. The feel is identical; only the space per sleeper changes.
Does the Sealy Claremont double work as a guest bed?
It's a sensible guest room choice. The medium firmness suits a wide range of sleepers, useful when you can't predict who's staying, and the double comfortably hosts visiting couples. Its footprint also fits most spare rooms alongside a wardrobe, so the room doesn't become all bed.
