Layer Details
- ActiveBreathe layer. This comfort layer feels like memory foam but is ten times more breathable, which means you get pressure relief without the heat build-up. It also allows ease of movement, so you shouldn't feel stuck in one position overnight.
- Mirapocket® spring system. Silentnight's pocket spring system, with 1400 springs in the king size, provides zoned support. In practice that means even weight distribution and improved spinal alignment, aimed at reducing aches and pains.
- Eternity layer. A base layer that gives the mattress extra stability and long lasting resilience. It's there to help the mattress hold its shape over years of use.

- A shared size for typical rooms: At 135 x 190cm, the UK double leaves space for bedside tables on both sides in most UK bedrooms, which a UK king often doesn't.
- Firm support with less roll-together: An extra firm surface flexes less under two different body weights, so a heavier partner is less likely to create a dip you roll into.
- Zoned support for both sleepers: The Mirapocket® spring system pushes back differently at hips and shoulders, which means each of you gets alignment suited to your own shape.
- Cooler sharing: Two people generate more heat than one, and the ActiveBreathe comfort layer is designed to let that warmth escape rather than trap it like standard foam.
- Easier to get upstairs: A UK double is a more manageable carry than a UK king through the turning stairs of an older terrace or a tight new build landing.
This size suits you if...
You share the bed every night and both prefer a firm, supportive surface, your bedroom is a typical UK size where you'd rather keep floor space than gain 15cm of bed width, or you sleep alone and want room to spread out, perhaps with a dog or cat claiming a corner, without giving the mattress the whole room.
Consider another size if...
You and your partner want more than 67.5cm each, or one of you is a restless sleeper. We'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double, and we suggest a room of at least 2.7m x 2.9m for it.

What are the dimensions of the Silentnight Revitalise Ortho 1400 in a UK double?
The UK double measures 135 x 190cm, which is 4ft 6in x 6ft 3in. It's the long standing standard for two people sharing in the UK, and the depth of 25.5cm is the same across every size of this mattress.
Is the UK double big enough for two on an extra firm mattress?
Two people sharing a UK double get 67.5cm each. That's workable for most couples, and the extra firm surface helps here: it flexes less under different body weights, so you're less likely to drift into a dip on your partner's side. If either of you sleeps starfish-style, consider the UK king.
What room size do I need for a double bed?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That guidance is ours, not Silentnight's. At the minimum you can still fit bedside tables on both sides in most rooms, which is often the deciding factor between a UK double and a UK king.
Should I choose the UK double or the UK king for this mattress?
The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the UK double if your room is close to our suggested 2.6m x 2.8m minimum, or if you want space to walk around the bed. Size up if you're both broad-shouldered or either of you is over 6ft, since the UK king adds length too.
Where can I buy the Silentnight Revitalise Ortho 1400 in a UK double?
This mattress is made by Silentnight exclusively for Furniture Village, so you can't shop it around between retailers for a better deal. The prices shown on this page are updated as the retailer changes them, so what you see here reflects the current UK double price.
