Layer Details
Comfort Layer
Soft white synthetic fibres sit at the top, which means a cosy surface feel rather than a sink-in one. They're durable and resilient, so the layer should hold its shape over time.
Support System
Traditional open coil springs are interlaced in a lattice design, which means the whole surface works together to spread your weight evenly. That helps relieve built-up pressure and supports spinal alignment, though it does mean more motion transfer than pocket springs if you share the bed.
Cover
A finely woven damask cover finishes the mattress, soft to the touch and built to last. It doesn't retain heat, which hot sleepers will appreciate.

Key benefits
- Room for two without crowding the bedroom: At 135 x 190cm, the UK double leaves space around the bed for a wardrobe and drawers in a typical second bedroom or a first flat.
- A firm shared surface: The interlaced springs spread weight across the full 135cm width, which means two sleepers of different builds both get the same firm, even support.
- A sensible guest room double: Visiting couples get a proper two-person bed, and the firm open coil feel suits occasional use in a room that stays furnished all year.
- Cooler for two: Two bodies generate more warmth than one, and the damask cover doesn't hold on to heat, which helps if either of you runs warm.
- Width to spare when you sleep alone: On your own, the UK double's 135cm width gives you room to stretch out, with space left over for a dog or cat that claims a corner.
- Easy to dress: Double sheets and a 200 x 200cm double duvet are stocked almost everywhere, which keeps bedding simple if you're furnishing a whole home at once.
This size suits you if...
You share a bed and your room can't comfortably take a UK king, or you're kitting out a guest room for visiting couples. It also fits if you sleep alone and want room to spread out on a firm, traditional spring bed.
Consider another size if...
You and your partner both like plenty of space, or one of you is over six foot. We'd recommend the UK king instead: we suggest at least 2.7m x 2.9m for the UK king.

FAQ's
Is the Romantica Serenade Ortho UK double wide enough for two adults?
It gives each of you 67.5cm, which most couples find workable. Because open coil springs pass on more movement than pocket springs, a light sleeper may notice a partner turning over. If that worries you, the UK king gives 7.5cm more each, though it needs a larger room.
Will a UK double Serenade Ortho fit my second bedroom?
Allow at least 2.6m x 2.8m, with around 3m x 3m being the comfortable norm. That usually leaves room for a wardrobe and drawers. If your room is tighter, the UK small double is 15cm narrower, and we suggest at least 2.4m x 2.8m for the UK small double.
Romantica Serenade Ortho double vs king: which suits a couple?
The UK double is 15cm narrower and 10cm shorter than the UK king, giving 67.5cm each rather than 75cm. Choose the UK double if space around the bed matters more to you. Choose the UK king if you want extra width for each of you and have at least 2.7m x 2.9m of floor.
Is the UK double Serenade Ortho long enough for tall people?
At 190cm, the UK double is the same length as the UK single and the UK small double. Taller sleepers who find their feet near the edge would be better on the UK king, which is 10cm longer than the UK double.
Is a Serenade Ortho UK double a good guest bed?
For visiting couples, yes. It's a proper two-person width, and the firm feel copes well with occasional use. Some owners describe the feel as closer to medium-firm, so guests who find very firm beds uncomfortable may still be fine.
