Layer Details
Soft Touch Quilted Cover
A quilted fabric finish that gives a smooth, breathable sleep surface. It adds a slightly softer first impression to what is otherwise a firm mattress.
Memory Foam
Memory foam, a material originally designed by NASA, moulds to the shape of your body, which means orthopaedic-style support where you need it. It's the layer that softens the firm feel just enough at your pressure points.
Supportive Miratex® Foam
Silentnight's Miratex foam conforms to your body as you sleep and provides edge to edge support across the entire mattress. In practice, that means a consistent feel whether you sleep in the middle or near the side.

Key benefits
- The traditional couples' size: At 135 x 190cm, the UK double is the long-established standard for two sharing, with 67.5cm each for two people sharing.
- Fits most UK bedrooms: Allow at least 2.6m x 2.8m and you'll still have space for bedside tables on both sides, where a UK king might crowd the walls.
- A slim 15cm profile that's easy to move: The shallow depth makes this double easier to carry up a turning staircase or across a tight landing than a bulkier mattress.
- Firm support across the full width: The Miratex foam base gives edge to edge support, which means two sleepers can use all 135cm without a soft, saggy border.
- Sensible for a guest room: A firm, low-cost double suits visiting couples well, giving proper shared space without spending main-bedroom money on a spare room.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet fit, and both are stocked everywhere at every price point.
This size suits you if...
You're a couple in a typical UK bedroom who prefers a firmer feel and wants the traditional shared size, you're furnishing a first flat or second bedroom on a budget and need a sensible double that leaves room for a wardrobe and drawers, or you're setting up a guest room for visiting couples and want proper shared space without a big spend.
Consider another size if...
You and your partner both want more personal space than 67.5cm each, and your room measures at least 2.7m x 2.9m. We'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double.

FAQ's
Is the Silentnight Hush Comfort double big enough for two adults?
It works for most couples. The UK double measures 135 x 190cm, giving 67.5cm each for two people sharing, and the Miratex base supports right to the edges so neither of you loses usable width. If either of you is tall or you both sprawl, the UK king is 15cm wider and 10cm longer.
What room size do I need for the Silentnight Hush Comfort in a UK double?
We suggest at least 2.6m x 2.8m. That leaves walking space around the bed and, in most rooms, enough wall width for bedside tables on both sides. The double suits typical UK bedrooms where a larger size would dominate; if your room is comfortably bigger, sizing up to the UK king is worth weighing.
Is the double easy to get upstairs in a smaller home?
Easier than most. At 15cm deep, this is a slim mattress, so a 135cm-wide double is lighter and more flexible to manoeuvre round a turning staircase in an older terrace or across a tight new build landing than a deeper double would be. Two people can manage it comfortably.
Should I choose the Silentnight Hush Comfort in a double or a single for a guest room?
For guests, the UK double is the safer choice because it accommodates visiting couples as well as solo visitors. It's 45cm wider than the UK single and the same length, and the firm feel suits a range of guests. Choose the UK single only if the room is genuinely tight; we suggest at least 2.1m x 2.8m for that size.
How big is the Silentnight Hush Comfort double in feet?
It measures 4ft 6in x 6ft 3in, which is 135 x 190cm. That's the standard UK double footprint, so any UK double bed frame, double sheets and a 200 x 200cm double duvet will fit it. Compare the retailers listed on this page for current prices in this size.
