Layer Details
Cover
A hard wearing Belgian damask cover with a hand tufted finish. The tufting isn't just decorative: it adds strength and helps the mattress hold its shape over time.
Fillings
Several layers of quality fillings, including white fibre, a lightweight, high loft material that's hypo-allergenic and keeps its shape, alongside Tencel. Tencel is a eucalyptus treated fibre that improves heat flow and moisture dissipation, which means less clamminess on warm nights.
Spring System
An extra firm open coil unit made of rows of hourglass shaped Bonnell springs, connected top and bottom by a helical wire running from head to foot. This gives a firm, uniform feel across the whole surface rather than the contouring you'd get from pocket springs.
Edge Support
A thick rod-edge wire strengthens the perimeter of the spring unit. In practice that means firmer edges to sit on and less of the border breakdown that cheaper open coil mattresses can suffer.

Key benefits
- The classic shared size: At 135 x 190cm, the UK double gives two sleepers 67.5cm each for two people sharing, the long standing standard for couples.
- Firm feel across the full width: The Bonnell spring unit gives a uniform, extra firm surface, which means neither side of the bed feels softer than the other.
- Edges you can use: A rod-edge wire strengthens the perimeter, so sleeping near your side of a shared UK double shouldn't mean rolling toward the edge.
- Fits typical UK rooms: We suggest allowing at least 2.6m x 2.8m, which most main bedrooms manage with space left for bedside tables on both sides.
- Cooler nights for two: Two bodies raise the temperature under the duvet, and the Tencel fibres in the fillings help move heat and moisture away.
This size suits you if...
You share the bed every night and want firm support without paying for pocket springs, or you're kitting out a guest room that needs to sleep visiting couples comfortably. It also suits anyone furnishing a first flat or a whole house at once, where a dependable double at a modest price frees the budget for everything else.
Consider another size if...
Your room comfortably exceeds 3m x 3m and one of you is a restless sleeper, since open coil springs pass movement across the bed. We'd recommend the UK king instead, which is 15cm wider and 10cm longer, giving each of you more space.

FAQ's
Is the Highgrove Solar Ortho Dream double big enough for two people?
Yes, for most couples. The UK double is the traditional shared size at 135 x 190cm, giving 67.5cm each for two people sharing. Because this mattress is extra firm with a rod-edge wire around the perimeter, you can use the full width right to the sides, which helps in a size where every centimetre matters.
What room size do I need for the Solar Ortho Dream in a UK double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves room to walk round the bed and fit bedside tables on both sides. If your room is a second bedroom already holding a wardrobe and drawers, measure the remaining floor space before committing.
Should I get this mattress in a UK double or a UK king?
The UK double is 15cm narrower and 10cm shorter than the UK king. If either of you is tall or you're often disturbed by a partner moving, the extra space of a UK king helps, and matters slightly more here because open coil springs transfer movement. In a typical sized room, the UK double is the sensible pick.
Will the UK double fit up the stairs of an older terrace?
Usually, yes. At 135cm wide and 27cm deep it's a manageable size, and doubles are the size delivery teams handle most often. Open coil mattresses shouldn't be bent or folded, though, so if your staircase has a tight turn or a small new build landing, measure the awkward point first.
Is a double a good choice for a guest room mattress?
It's the safest guest room size, since it sleeps visiting couples as well as solo guests. The firm, even feel of the Bonnell springs is a reasonable fit for occasional use too, where you can't tailor the mattress to one person's preference. The modest price at this size also suits a room that's only used now and then.
