Key benefits
- 75cm each for couples: Two people sharing get 75cm of width apiece, so an early alarm on one side is less likely to wake the other.
- Extra length for taller sleepers: At 200cm long, the UK king adds 10cm over a UK double, welcome if either of you is approaching six foot.
- Mini pocket springs across a wider bed: Pocket springs respond individually, which means movement on one half of the 150cm width transfers less to the other.
- Memory foam where couples need it: The visco-elastic memory foam layer cushions hips and shoulders, useful when two sleepers with different builds share the same surface.
- Fits a normal master bedroom: We suggest a room of at least 2.7m x 2.9m, which most UK master bedrooms manage without sacrificing wardrobe space.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, especially if one of you gets up hours before the other. It also makes sense if either partner is tall, since the 200cm length is a genuine upgrade over a double, or if a dog has quietly become a permanent third occupant taking more than its share.
Consider another size if...
Your bedroom falls below our suggested 2.7m x 2.9m minimum, or you sleep alone and don't need the width. The UK double of the Emma Hybrid would suit you better and leave more floor space.

FAQ's
Is the Emma Hybrid UK king big enough for a couple?
Comfortably, for most. At 150cm wide you each get 75cm, which is 15cm more shared width than a UK double offers. Across the mini pocket spring layer, that extra space plus individually responding springs means less disturbance when one of you turns over or gets up early.
Will the Emma Hybrid king suit a tall sleeper?
The UK king is 200cm long, 10cm more than a UK double, so anyone approaching six foot gains real toe room. If both of you are tall and broad, the UK super king keeps the same 200cm length with 30cm more width.
What room size do I need for the Emma Hybrid in a UK king?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m the comfortable point where you can walk both sides and still fit wardrobes. New build masters can be smaller than they look once fitted furniture goes in, so measure the clear floor before ordering.
How much bigger is the king than the small double for this mattress?
The UK king is 30cm wider than the UK small double and 10cm longer, which is the difference between a snug fit for two and proper space each. For regular sharers, the UK king is the more sustainable long-term choice of the Emma Hybrid's sizes.
What bedding fits the Emma Hybrid king?
Standard UK king sheets fit the 150 x 200cm mattress, and a 230 x 220cm king duvet is the usual pairing. Some couples upgrading from a double keep a bigger duvet than the bed strictly needs, which helps if one of you hogs the covers.
