Key benefits
- A shared size that fits the room: At 135cm wide, this double gives couples a proper shared bed while leaving space for a wardrobe and bedside tables on both sides in an average UK bedroom.
- Less partner disturbance in a shared width: Memory foam absorbs movement rather than bouncing it across the mattress, which matters more at 67.5cm each for two people sharing than in a bed you have to yourself.
- Zoned support for two different bodies: The 7-zone base firms up where each sleeper is heaviest, so partners of different weights both get support across the shared surface.
- Cooling designed with sharing in mind: Two bodies generate more heat than one, so the cooling cover and open-cell foam are a genuine help at this shared size, especially for warmer sleepers.
- The easiest size to dress: Double sheets and 200 x 200cm duvets are sold everywhere at every price, so replacing bedding never becomes a hunt.
This size suits you if...
You share the bed most nights and your room sits comfortably above our suggested 2.6m x 2.8m minimum, or you sleep alone and want space to stretch out, perhaps with a pet claiming a corner. It also suits a guest room that regularly hosts visiting couples, where the contouring foam gives a forgiving surface without demanding a large room.
Consider another size if...
You and your partner both sleep on your backs or find yourselves nudging elbows, since 67.5cm each is workable rather than generous. If your room allows at least 2.7m x 2.9m, we'd recommend the UK king instead for 7.5cm more width each.

FAQ's
Is a UK double Nectar mattress big enough for two adults?
It works for most couples, giving 67.5cm each for two people sharing. The memory foam helps here, as it absorbs movement so you feel less of a partner turning over. That said, restless sleepers or broader builds may feel the limit. If your room takes at least 2.7m x 2.9m, the UK king gives 75cm each.
What room size do I need for the Nectar double mattress?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows bedside tables on both sides plus a wardrobe without the bed dominating the space, which is exactly why the UK double remains the default choice for typical British bedrooms.
Should I get the Nectar in a double or a king?
The UK double is 15cm narrower and 10cm shorter than the UK king, and the UK king gives each sharer 7.5cm more width. If your bedroom comfortably exceeds 2.7m x 2.9m and either of you is tall or a sprawler, size up. In a smaller room, the double keeps walking space around the bed.
Will the Nectar double fit up the stairs in an older house?
Being all foam, it arrives rolled and compressed in a box, which is far easier to carry round the turning stairs of an older terrace or across a tight new build landing than a rigid sprung double. Once unrolled it expands to the full 135 x 190cm, so plan the route into the room before opening it.
Where can I buy the Nectar Memory Foam Mattress in a double?
Compare the retailers listed on this page. The prices shown here are updated as retailers change them, so it's the quickest way to see who currently stocks the UK double and at what price, rather than checking each retailer separately.
