Layer Details
Pillow top comfort layer
A plush pillow top packed with natural fibres and mini springs, giving a sink-in feel. It means a soft, cushioned surface that eases you into the mattress.
Pocket spring core
1,000 traditional pocket springs form the heart of the mattress, with 8,000 mini pocket springs blended into the comfort filling layers. That gives the medium feel and a supportive base under the softer top.

Key benefits
- Space left around the bed: We suggest at least 2.6m x 2.8m for a UK double, so many bedrooms can keep a bedside table on each side and a wardrobe that still opens.
- A soft top for two: Each sleeper gets 67.5cm of pillow top, which suits couples who sleep close, although two broad-shouldered adults may find it slightly tight.
- Usable edges in a narrower bed: The reinforced edge with butterfly border springs means the outer few centimetres stay supportive, which matters more when two people share a UK double.
- Easy bedding: Double sheets fit a 135 x 190cm mattress and a 200 x 200cm double duvet covers you both, though the 34cm depth calls for deep fitted sheets.
- Suits a guest room: If you put up visiting couples, a UK double gives them a proper shared bed with a cushioned feel while leaving room for a chest of drawers.
This size suits you if...
You share the bed with a partner in a typical main or second bedroom, you want a soft-topped bed without handing floor space to a UK king, or you're furnishing a guest room where couples stay.
Consider another size if...
You both sprawl, or one of you is tall and likes legroom. We'd recommend the UK king instead, which gives 75cm each and is 10cm longer; allow at least 2.7m x 2.9m.

FAQ's
Is the Wentworth Mercer Premium 9000 Pocket Pillow Top double big enough for two people?
For most couples, yes. A UK double gives 67.5cm each, which feels comfortable if you sleep fairly close. If one of you turns a lot, the UK king gives 7.5cm more each and could suit you better.
What size bedroom do I need for a UK double Premium 9000 Pocket Pillow Top?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm if you want bedside tables on both sides and space to walk round. The mattress itself measures 4ft 6in x 6ft 3in.
What sheets fit a 34cm deep UK double mattress?
Look for double fitted sheets with a deep pocket, because standard ones can pull off the corners of a 34cm mattress with a pillow top. A 200 x 200cm double duvet covers two sleepers comfortably.
How much smaller is a UK double than a UK king?
The UK double is 15cm narrower and 10cm shorter than the UK king. For two sharing, that is 7.5cm less each. In return, we suggest a smaller room: at least 2.6m x 2.8m, against 2.7m x 2.9m for the UK king.
Should a solo sleeper with a dog choose a double or small double?
If your dog or cat claims a corner most nights, the UK double is 15cm wider than the UK small double, which gives you both more room. If your room is tight, we suggest at least 2.4m x 2.8m for the UK small double.
