Layer Details
Soft White Fibres
Soft synthetic fillings topped with a polyester layer, which means a cosy surface feel the moment you lie down. They're inherently breathable, so this comfort layer shouldn't hold onto heat.
Wool
A generous layer of natural wool fibres gives deep, plush comfort. Wool is naturally temperature-regulating, which means it works all year round, warming in winter and wicking heat in summer.
Pocket Springs
3000 traditional pocket springs made from twice tempered steel, which means each spring responds to your body shape independently rather than the whole surface moving as one. The result is strong, personalised support and less partner disturbance.

Key benefits
- Room to share, room to move: At 135cm wide you each get 67.5cm, which is enough for most couples while still leaving floor space around the bed in an average UK bedroom.
- Less disturbance at close quarters: The 3000 pocket springs move independently, which means a partner turning over beside you is less likely to wake you on a width where you sleep fairly close.
- Wool helps two sleepers stay comfortable: Two people generate more warmth than one, and the natural wool layer regulates temperature, so the surface should feel less stuffy on warmer nights.
- Fits where a UK king would dominate: We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m feeling comfortable, so bedside tables on both sides remain realistic in most rooms.
- Easy to dress: Double sheets are stocked almost everywhere, and a 200 x 200cm double duvet gives both of you enough cover without a bulky overhang.
This size suits you if...
You share with a partner in a standard-sized bedroom and want space for a bedside table each, or you're setting up a second bedroom where visiting couples will stay, and you like the idea of natural wool over pocket springs.
Consider another size if...
You and your partner both sprawl, or one of you is broad-shouldered and 67.5cm each already feels tight. We'd recommend the UK king instead; we suggest at least 2.7m x 2.9m for the UK king.

FAQ's
Is the Wentworth Mercer Deluxe Wool 3000 double good for couples who disturb each other?
It should help. The 3000 pocket springs respond individually, so movement on one side travels less to the other. That matters in a UK double, where you each have 67.5cm and sleep closer together than in a UK king. If one of you is a very restless sleeper, the extra width of the UK king may suit you better.
Will the Wentworth Mercer Deluxe Wool 3000 in a UK double fit a bedroom with bedside tables?
In most UK bedrooms, yes. We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m giving comfortable space to walk round the bed. Measure your room first, and remember the bed frame usually adds a little to the 135 x 190cm mattress footprint.
Wentworth Mercer Deluxe Wool 3000 double or king: is the upgrade worth it for a couple?
The UK king is 15cm wider and 10cm longer, giving you 7.5cm more each. That is a real difference for tall or restless couples, but it needs more floor: we suggest at least 2.7m x 2.9m for the UK king, against 2.6m x 2.8m for the UK double.
Is the UK double Wentworth Mercer Deluxe Wool 3000 long enough for a tall partner?
The UK double is 190cm long, or 6ft 3in. Most people fit comfortably, but if either of you is close to that height, feet may reach the end. The UK king and UK super king are both 10cm longer, which is the simplest fix for a tall sleeper.
Is the Wentworth Mercer Deluxe Wool 3000 double a good choice for a guest room?
It works well for a guest room that hosts couples, because 135cm gives two visitors a genuine shared bed rather than a squeeze. If your guests are mostly single, the UK small double is 15cm narrower and we suggest at least 2.4m x 2.8m for it, which frees up space in a smaller room.
