Layer Details
Latex comfort layer
A latex layer that gives pressure relief adjusting with your movements, so the surface follows you as you shift position.
Sealy Premium Medium Foam
Sealy premium foam combined with latex to create the medium feel, which gives a balanced, not-too-soft surface.
Sealy Premium Firm Foam
A second Sealy premium foam layer, in firm, completing the comfort stack. It adds a firmer base so you don't sink too far.
PostureTech Core Support Plus springs
High-profile, 6-turn springs, twice tempered, forming the core support. They give the mattress its underlying support and structure.

Key benefits
- Room for two, room to move: At 135 x 190cm, the UK double leaves walking space around the bed in most UK bedrooms, so bedside tables on both sides usually still fit.
- Edges you can sleep near: UniKey edge support helps the sides hold up, which means whoever sleeps nearest the edge of a 67.5cm half should feel a little steadier there.
- A surface that keeps up as you turn: The latex comfort layer is described as adjusting with your movements, which helps on a 67.5cm half where you turn over in place rather than shifting sideways.
- A medium feel most couples can share: Sealy rates the Kindra medium, a sensible middle ground when two people with different preferences need to agree on one mattress.
- Easy bedding to buy: Double sheets and a 200 x 200cm double duvet fit, and they're sold almost everywhere, which helps when you're furnishing a whole flat at once.
This size suits you if...
You share a bed every night in a typical UK bedroom and still want bedside tables on both sides, you sleep alone and like space for a cat or dog to claim a corner, or you're setting up a guest room for visiting couples.
Consider another size if...
You and your partner both sleep spread out and 67.5cm each already feels tight. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m for the UK king.

FAQ's
Is the Sealy PostureLux Kindra UK double big enough for two adults?
For most couples, yes. The UK double gives 67.5cm each when two people share, and the UniKey edge support helps the sides hold up, so the edges stay usable. If either of you sleeps starfish-style or you're both tall, the UK king gives 75cm each and is 10cm longer.
What size bedroom do I need for a Sealy Kindra UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m feeling comfortable once you add bedside tables and a wardrobe. In a smaller second bedroom, check where the doors and drawers open before you commit, because the bed itself is rarely the problem.
Sealy PostureLux Kindra UK double or UK king for a couple?
The UK double is 15cm narrower and 10cm shorter than the UK king, giving 7.5cm less each when sharing. Choose the UK double if your room is tight or you want space to walk round the bed. The UK king needs at least 2.7m x 2.9m by our guidance.
Sealy PostureLux Kindra double dimensions in feet and inches?
The UK double is 4ft 6in x 6ft 3in, or 135 x 190cm. It's 30cm deep, so check that your fitted sheets suit that depth. If you live in an older terrace with turning stairs, measure the turn first, then compare the retailers listed on this page.
What bedding fits a UK double Sealy Kindra?
Standard double sheets fit the 135 x 190cm surface, and a 200 x 200cm double duvet covers it comfortably for two. Look for fitted sheets made for deeper mattresses, as the Kindra is 30cm deep.
