- A shared size for typical rooms: At 135 x 190cm, the UK double fits most UK bedrooms with room left for wardrobes and drawers, which a UK king often doesn't.
- 67.5cm each for couples: Two people sharing get 67.5cm each, enough for most couples, and the firm surface keeps you settled on top rather than rolling together.
- Firm support that works for two: A firm feel resists sagging toward the heavier sleeper, which means you're less likely to disturb each other when one of you turns over.
- Bedside tables on both sides: In a room of around 3m x 3m, a UK double usually leaves space for a table each side, something a wider size can rule out.
- Easy to dress: Standard double sheets and a 200 x 200cm duvet are stocked everywhere at every price, so bedding never becomes a hunt.
This size suits you if...
You share the bed every night and your room is a typical UK size, or you sleep alone and want space to spread out, perhaps with a dog or cat claiming their usual corner. It also suits a guest room that hosts visiting couples: the firm feel of the Decadence gives most guests reliable support without you needing to know their sleep preferences in advance.
Consider another size if...
You and your partner both like plenty of personal space, or one of you is a restless sleeper. We'd recommend the UK king instead, which is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m of floor space for it.

Is the Sealy Decadence UK double big enough for a couple?
Yes, for most couples. The UK double gives two people 67.5cm each, and because the Decadence is firm, you stay on your own side of the surface rather than sinking toward the middle. Broader couples, or anyone who sprawls, may find it a little snug, in which case the UK king is the sensible step up.
What room size do I need for a UK double Sealy Decadence?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That larger figure usually leaves room for bedside tables on both sides plus a wardrobe, which matters if this is going in a first flat or a second bedroom where every bit of floor counts.
Should I buy the Sealy Decadence in a UK double or a UK king?
It mostly comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, so it fits where a king would dominate. If you have at least 2.7m x 2.9m to spare and you both like space, size up. If the room is tighter, the UK double is the better balance.
What are the dimensions of the Sealy Decadence double?
The UK double measures 135 x 190cm, which is 4ft 6in x 6ft 3in. It takes standard double sheets and a 200 x 200cm double duvet, both widely stocked. Anyone over about 6ft 3in tall will want the extra 10cm of length the UK king offers.
Is a UK double Sealy Decadence a good choice for a guest room?
It's a strong fit. The size accommodates visiting couples as well as solo guests, and the firm feel suits back and front sleepers, which covers most people passing through. Lightweight side sleepers may find it a touch too firm at the shoulder, but for occasional use that's rarely a dealbreaker.
