Layer Details
- Knitted Cover. A soft knitted cover that's breathable, which means heat can escape rather than build up around you. It helps keep your temperature even through the night.
- Cooling Gel Fusion™ Memory Foam. Gel memory foam that feels cool to the touch and gently contours to your body. You get pressure relief at the shoulders and hips without the warmth traditional memory foam is known for.
- 1500 Pocket Springs. Each of the 1500 springs sits in its own fabric pocket and works independently of its neighbours. That means support adjusts to your shape and movement transfers less across the mattress.

- Space for bedside tables: We suggest at least 2.6m x 2.8m for the UK double, and around 3m x 3m gives you comfortable room for a bedside table on each side.
- Less disturbance at close quarters: You get 67.5cm each for two sharing, and the 1500 independent pocket springs mean a partner turning over is less likely to jolt your side.
- Cooler when you sleep close: Sharing a UK double keeps two bodies near each other, so the gel memory foam layer, which feels cool to the touch, helps stop warmth building between you.
- Simple to dress: Double sheets and a 200 x 200cm double duvet are sold almost everywhere, so kitting out the bed or keeping a spare set is straightforward.
- A proper bed for guests: In a spare room, the medium firm feel suits most visitors, and visiting couples get a genuine shared bed rather than a sofa bed.
This size suits you if...
You share the bed with a partner in a typical UK bedroom and want to keep room for bedside tables and a wardrobe, you're furnishing a guest room for visiting couples, or you sleep alone and like enough width for a cat or dog to settle at your feet.
Consider another size if...
You're both tall or like plenty of space to sprawl, and 67.5cm each would feel tight. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m.

Is the Affinity Ortho 1500 UK double wide enough for two people?
It gives 67.5cm each for two sharing, which suits most couples who sleep fairly still. Because the 1500 pocket springs move independently, a restless partner is less likely to wake you even at close quarters. If either of you spreads out, the UK king gives 7.5cm more each.
What is the Tuft & Springs Affinity Ortho 1500 double size in feet?
The UK double measures 4ft 6in x 6ft 3in, or 135 x 190cm. It follows the standard UK double footprint, but check it against your bed frame's internal measurements before you buy, particularly with older or antique frames.
Will an Affinity Ortho 1500 UK double fit a small bedroom with bedside tables?
We suggest at least 2.6m x 2.8m for the UK double. Around 3m x 3m is more comfortable if you want bedside tables on both sides plus a wardrobe and drawers. In a second bedroom or first flat, measure the wall the headboard will sit against first.
Affinity Ortho 1500 UK double or UK king for a couple?
The UK double is 15cm narrower and 10cm shorter than the UK king, giving 7.5cm less each. Choose the UK double if your room is closer to our suggested 2.6m x 2.8m; the UK king needs at least 2.7m x 2.9m. Taller couples may appreciate the UK king's extra length.
Is the Affinity Ortho 1500 double good for a guest room?
For visiting couples, yes. The medium firm feel suits most sleepers, although lightweight side sleepers may find it a little firm at the shoulder. Double bedding is easy to find, so keeping a fresh set in the cupboard for visitors is simple.
