Layer Details
- Soft Knitted Cover. A breathable knitted cover that's soft to the touch, which means the firm build doesn't feel harsh against your skin. It gives the mattress a slightly more luxurious finish than you might expect at this price.
- Soft White Fibres. Fibre fillings made from 100% polyester sit beneath the cover, offering good recovery and durability. In practice, this means a comfort layer that springs back rather than developing dips quickly.
- Open Coil Springs. Interlaced coils of high-tensile steel joined together in a lattice, which means the springs work as one connected system to support your body. This is a traditional construction, so expect firm, even support rather than the isolated contouring of pocket springs.

- The traditional couples' footprint: At 135 x 190cm, or 4ft 6in x 6ft 3in, this is the size most UK bedrooms were designed around, so bedside tables on both sides usually still fit.
- Firm support across the whole width: The lattice of high-tensile open coils works as one connected surface, which means neither of you ends up in a softer patch near the edge.
- Sensible for a room around 2.6m x 2.8m: We suggest at least 2.6m x 2.8m for a UK double, which leaves walking space where a UK king would start to crowd the furniture.
- Easy to dress on a budget: Double sheets and 200 x 200cm duvets are stocked everywhere at every price, useful if you're kitting out a whole home at once.
- A dependable guest room size: Visiting couples can share it comfortably, and the firm, even feel tends to divide opinion less than very soft mattresses do.
This size suits you if...
You share the bed every night and your room sits around the typical UK size, where a UK king would leave the space feeling cramped. It also suits you if you're furnishing a guest room that needs to sleep visiting couples, or setting up a first flat where the budget has to stretch across every room and a firm, no-frills mattress does the job.
Consider another size if...
You and your partner disturb each other easily, since open coils transfer movement more than pocket springs, and a bit more distance helps. The UK king gives 75cm each rather than 67.5cm; allow at least 2.7m x 2.9m for it.

Is the Daphne Ortho in a UK double big enough for two people?
For most couples, yes. You get 67.5cm each when two people share, which is the long standing UK standard. Bear in mind the open coil springs are joined in a lattice, so you'll feel more of your partner's movement than you would with pocket springs. If one of you is a restless sleeper, extra width helps.
How much space does each person get on the UK double Daphne Ortho?
Two people sharing get 67.5cm each across the 135cm width. That's enough for most couples to sleep comfortably, though noticeably snugger than the UK king, which gives 75cm each. If you both like to spread out, or one of you shares with a dog or cat that claims a corner, consider sizing up.
Will a UK double fit my bedroom with bedside tables on both sides?
Usually, yes, and that's a big part of the UK double's appeal. We suggest a room of at least 2.6m x 2.8m, which typically leaves enough clearance for a table each side plus a wardrobe or chest of drawers. Measure the wall the bed will sit against before ordering, especially in older houses with chimney breasts.
Should I choose the Daphne Ortho in a UK double or a UK king?
The UK double suits rooms around the 2.6m x 2.8m mark; the UK king is 15cm wider and 10cm longer, and we'd allow at least 2.7m x 2.9m for it. Because the Daphne Ortho's open coils carry movement across the bed, light-sleeping couples with the room to spare may prefer the extra distance the UK king provides.
Is the Daphne Ortho UK double a good choice for a guest room?
It's well suited to one. The UK double handles visiting couples as well as solo guests, and the firm, even surface is a safe middle ground for people whose preferences you don't know. Since a guest bed sees lighter use than an everyday one, the simple traditional build matters less here than it might in your own room.
