- Room for two, at last: At 135cm wide, two people sharing get 67.5cm each, which means you can both settle without negotiating every turn.
- Fits a typical UK bedroom: We suggest a room of at least 2.6m x 2.8m, which most doubles-era British bedrooms manage while still leaving space for a wardrobe and drawers.
- The biggest option in the range: This model tops out at the UK double, so if you're sharing, this is the size to have.
- Bedding is easy to find: Double sheets and duvets are stocked everywhere at every price, handy if you're kitting out a first flat on a tight budget.
- Steady support for two: Medium firm tension holds back and front sleepers level, which matters more in a shared bed where two body weights meet one surface.
This size suits you if...
You share the bed every night and want the traditional couples' size without a king-sized footprint, you're furnishing a first flat or a whole home and need a full-size shared bed at a modest price, or you sleep alone but like space to spread out, perhaps with a dog or cat claiming a corner.
Consider another size if...
Your room is under our suggested 2.6m x 2.8m, or the bed is for one child or teenager. The UK small double is 15cm narrower at the same length and needs only 2.4m x 2.8m, and for a child's room we'd recommend the UK single instead.

Is the Silentnight Healthy Growth double big enough for two adults?
It works for most couples. At 135cm wide you get 67.5cm each for two people sharing, which is comfortable for average builds, although broader sleepers or restless partners may notice the limit. Since this model doesn't come in a UK king, the UK double is the most space this mattress can offer a couple.
What size room do I need for a double Silentnight Healthy Growth?
We suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That allows walking space on both sides and, in most rooms, bedside tables too. Measure with the door swing and wardrobe doors in mind before you commit.
Does the Silentnight Healthy Growth come in a UK king?
No. The range runs UK single, UK small double and UK double, so the UK double is the largest available. Couples set on a bigger bed will need a different mattress; the UK king is 15cm wider and 10cm longer than the UK double, and we suggest at least 2.7m x 2.9m of room for it.
Should I choose the double or the small double in this mattress?
For two people sharing every night, the UK double. It's 15cm wider than the UK small double at the same length, and that extra width is the difference between sleeping and coexisting. The UK small double suits a solo sleeper in a compact room, or a guest bed used occasionally by visiting couples.
Will a UK double mattress get up a narrow staircase?
Usually, yes. A sprung double measures 135 x 190cm and has some flex, though less than an all-foam mattress, so tight turns in older terraces or narrow new build landings deserve a tape measure first. Check the turn on your stairs against the 135cm width before ordering, and clear the route on delivery day.
