Layer Details
Stretch knit cover
A stretch knit fabric with a hand-tufted finish that keeps the fillings in place. It means the surface stays neatly held together rather than shifting around over time.
Memory foam layer
Temperature-sensitive memory foam that reacts to body heat and moulds to your contours. This gives you pressure relief at the shoulders and hips, with a slower, hugging feel when you lie down.
Small diameter pocket spring layer
The core is a layer of small diameter pocket springs. It forms the supportive base of the mattress and sits underneath the comfort layers.
Mini comfort tablet pocket springs
Two layers of mini comfort tablet pocket springs sit on top of the core, each spring housed in its own cloth sleeve. Because each spring works on its own, the mattress can respond to your body in a more targeted way.

Key benefits
- Sized for ordinary bedrooms: We suggest at least 2.6m x 2.8m for a UK double, which means most main and second bedrooms can take it without the bed filling the floor.
- Room to share: Two people sharing get 67.5cm each, which suits couples who sleep fairly close and don't mind the occasional brushed elbow.
- Space left for bedside tables: At around 3m x 3m, a UK double usually leaves enough clearance for a small table on each side as well as a walkway at the foot.
- Generous for one: If you sleep alone, the 135cm width gives you room to stretch diagonally, with space left over for a pet who insists on joining you.
- Easy to dress: Double sheets and a 200 x 200cm double duvet fit this size, and both are widely stocked, so you won't need to hunt for bedding.
This size suits you if...
You share with a partner in a bedroom of ordinary size and want to keep space for a wardrobe and chest of drawers, or you sleep on your own and like enough room for a cat or dog to settle at the foot of the bed.
Consider another size if...
You and your partner both like to spread out, or either of you finds 190cm a little short. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
How much space per person does the Hilton Memory Pocket 4000 UK double give?
Two people sharing the UK double get 67.5cm each. That is 7.5cm less each than the UK king version and 22.5cm less each than the UK super king. For most couples who sleep close, 67.5cm is comfortable, although restless sleepers may notice a partner's movements more at this width.
Is the UK double the smallest size of the Sweet Dreams Hilton Memory Pocket 4000?
Yes. The UK double is the smallest size of this mattress, as there is no single or small double version. If you need something narrower for a box room or a child's bedroom, you'll have to look at a different mattress.
Hilton Memory Pocket 4000 double vs king: how much bigger is the king?
The UK king is 15cm wider and 10cm longer than the UK double. It also needs more floor space: we suggest at least 2.7m x 2.9m for the UK king, against 2.6m x 2.8m for the UK double. In a tight room, those extra centimetres can decide whether bedside tables still fit.
What are the Hilton Memory Pocket 4000 double dimensions in feet?
The UK double measures 4ft 6in x 6ft 3in, which is 135 x 190cm. Use these figures to check your bed frame before ordering, since a frame built for a UK king or a European size won't hold this mattress properly.
Is a double Hilton Memory Pocket 4000 a good choice for a guest room?
For a spare room that hosts visiting couples, the UK double is a sensible fit. It gives two guests 67.5cm each while leaving space for a chest of drawers or a desk. If the guest room also has to double as an office, allow at least 2.6m x 2.8m.
