Layer Details
Pillow top
A luxuriously plump pillow top sits on the surface, which means a softer, more cushioned first feel before you reach the supportive layers beneath.
Damask fabric
The mattress is wrapped in soft-touch damask fabric. It gives the sleeping surface a smooth, gentle finish against bedding.
Silk and mohair blend
A silk and mohair blend brings sumptuous softness and helps regulate temperature. In practice that means the mattress should feel less clammy if you run warm at night.
Platinum 3D polyester
This Platinum 3D polyester layer is fully recyclable at the end of its life, a small but genuine environmental plus for a mattress in this bracket.
Pocket springs
Individually wrapped pocket springs distribute body weight evenly for head-to-toe support. Because each spring moves independently, you should feel less disturbance when a partner shifts position.

Key benefits
- A shared size that leaves the room usable: At 135cm wide, the UK double gives two people a proper bed while leaving space for wardrobes and bedside tables on both sides in most bedrooms.
- 67.5cm each for two sharing: Two people sharing get 67.5cm each, and because each of the 10,000 pocket springs moves independently, a partner turning over is less likely to wake you.
- Cool enough for two bodies: Sharing a bed raises the temperature under the duvet, and the silk and mohair blend in the upper layers helps keep the surface from feeling clammy.
- Easy to dress, easy to replace: Double sheets and 200 x 200cm duvets are stocked everywhere, though the 30cm depth means you'll need deep fitted sheets rather than standard ones.
- A sensible pick for a guest room: If this is for visiting couples rather than everyday use, the medium-firm tension suits side, front and back sleepers, so most guests will settle in fine.
This size suits you if...
You share the bed every night 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 dog or cat claiming a corner. It also makes sense for a guest room that hosts couples, where the Boulton's medium-firm tension covers most sleeping positions without you knowing your visitors' preferences in advance.
Consider another size if...
You're both restless sleepers and 67.5cm each feels tight, or your room is generously sized. The UK king is 15cm wider and 10cm longer, and we suggest at least 2.7m x 2.9m for it.

FAQ's
Is a double Boulton mattress big enough for two adults?
It gives two people sharing 67.5cm each, which most couples find workable rather than roomy. The Boulton's individually wrapped pocket springs reduce how much you feel a partner move, which helps at this width. If either of you is tall or spreads out in the night, the UK king, 15cm wider and 10cm longer, is worth considering.
Will the Boulton in a UK double fit my bedroom?
The mattress is 135 x 190cm, and we suggest a room of at least 2.6m x 2.8m so you can still open drawers and walk round the bed. Around 3m x 3m is the comfortable norm, with space for bedside tables on both sides. Measure with your wardrobe doors open before committing.
Should I get the Boulton in a double or a king?
Choose the UK double if your room is near our 2.6m x 2.8m suggested minimum, or if it's a guest room used occasionally. Choose the UK king, which is 15cm wider and 10cm longer, if you share every night and the room measures at least 2.7m x 2.9m. The feel and construction are identical in both.
What bedding fits the double Boulton mattress?
Standard double sheets and a 200 x 200cm double duvet, both stocked everywhere at every price point. One caveat: the Boulton is 30cm deep, so a standard fitted sheet may pop off the corners. Check the depth rating on the packaging and buy deep or extra-deep fitted sheets to be safe.
Where can I buy the Boulton in a UK double?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them, so what you see reflects current pricing rather than a snapshot.
