Sealy Imperial Contract Memory Double Mattress
The Sealy Imperial Contract Memory Mattress pairs memory foam with a sprung core, which means you get that slow, cradling surface feel without the sunk-in softness an all-foam bed can have.
- Shallow hug, easy to change position
- Eases pressure at hips & shoulders

Layer Details
MemorySense foam
Sealy's MemorySense foam sits on top and contours to your shape, easing weight off pressure points like hips and shoulders. You feel it as a gentle, relieving cradle rather than a firm surface.
Reflex Foam
A firm Reflex foam layer follows, contouring to your body while stopping you sinking too deeply. In practice this keeps the memory foam feel shallow and supportive, which makes changing position easier.
PostureTech Core Support Springs
Sealy's PostureTech springs form the core and become firmer when met with pressure, so support increases exactly where your body pushes hardest. The tops of the springs are made to a softer tension, which means they follow your shape rather than feeling rigid.

Key benefits
- A shared size that fits real rooms: At 4ft 6in x 6ft 3in, the UK double leaves space for wardrobes and drawers where a UK king would crowd the walls.
- 67.5cm each for two sharing: Two people get 67.5cm apiece, and the medium firm feel limits roll-together so you each stay in your own lane.
- Room for bedside tables both sides: We suggest a room of at least 2.6m x 2.8m, which in most doubles still leaves space for a table on each side.
- Depth that suits a couples' bed: The 31cm build gives a raised, hotel-style height, so check your headboard and fitted sheets are made for deep mattresses.
- Easy to dress on any budget: Standard double sheets and duvets are sold everywhere, useful if this is going in a guest room you dress occasionally.
- Firm enough for two different sleepers: The memory foam cradles each of you individually while the springs firm up under the heavier partner, so mismatched weights are handled well.
This size suits you if...
You're a couple in a typical UK bedroom and want a proper shared bed without giving the whole room over to it, or you're kitting out a guest room where visiting couples stay and a double is the practical standard. It also suits a solo sleeper who likes to spread out, or shares the mattress with a pet that claims a corner every night.
Consider another size if...
You both like space and your bedroom measures at least 2.7m x 2.9m. In that case we'd recommend the UK king instead: it's 15cm wider and 10cm longer, which two adults feel every night.

FAQ's
Is the Sealy Imperial Contract in a UK double big enough for a couple?
For most couples, yes. You get 67.5cm each for two people sharing, and the mattress helps that width go further: the PostureTech springs firm up under whoever presses hardest, so a heavier partner doesn't pull the lighter one into a dip. If one of you is broad-shouldered or a restless sleeper, the UK king's extra 15cm of width is a real upgrade.
What size room do I need for the UK double Sealy Imperial Contract?
We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. The mattress itself is 135 x 190cm, so in a typical UK double bedroom you should still manage bedside tables on both sides. Do factor in the 31cm depth: on a tall divan base the bed can dominate a small room visually.
Should I buy the Sealy Imperial Contract in a double or a king?
Choose the UK double if your room is on the smaller side or you want space for other furniture; choose the UK king if two of you share every night and the room allows at least 2.7m x 2.9m. The UK king is 15cm wider and 10cm longer, and that extra length helps anyone approaching six feet tall.
Is a UK double Sealy Imperial Contract a good choice for a guest room?
It's a sensible one. A UK double suits visiting couples and solo guests alike, fits most spare rooms, and standard double bedding is cheap and easy to find. The medium firm feel is the safest bet for guests whose preferences you don't know, although very light side sleepers may find it slightly firm at the shoulder.
