Layer Details
Cover
The top cover of the mattress.
Airgocell foam layer
Emma's Airgocell foam sits beneath the cover, which means a cushioned, pressure-relieving surface where your body first meets the mattress.
SupportBase foam
A supportive foam layer that sits between the comfort foam and the springs, helping to keep your spine aligned.
3-zone pocket spring core
A pocket spring core divided into three zones, with a wraparound comfort foam edge. The zoning means support is tailored to different parts of your body, while the foam edge keeps the perimeter feeling stable.

Key benefits
- Room to move without disturbing anyone: At 75cm each for two people sharing, one of you can get up early or shift about while the other stays comfortably in their own space.
- Extra length for taller sleepers: The 200cm length means anyone approaching six foot sleeps with their feet on the mattress rather than hanging off it.
- Usable edges make the width count: The wraparound comfort foam edge keeps the perimeter stable, so you can sleep close to your side of a 150cm mattress without feeling you might roll off.
- Zoned support across a bigger surface: The 3-zone pocket spring core adjusts support along your body, which means each sleeper gets firmer support at the hips and a softer feel at the shoulders.
- Slim profile, easier handling: The 22cm depth keeps this king lighter to rotate and make up than deeper hybrids, a small practical win at this width.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, one of you is up hours before the other and you'd rather they left the bed unnoticed, or either of you is tall enough that the extra length matters as much as the width. It also suits couples whose dog treats the bed as its own and takes more than its share.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a king, or you sleep alone. The UK double of the Emma Original Lite would suit a smaller room better, and for solo sleepers the UK double is still generous.

FAQ's
Is the Emma Original Lite in a UK king big enough for a couple?
Yes, comfortably for most. Two people sharing get 75cm each, and the wraparound comfort foam edge means the full 150cm width is usable rather than the outer strip feeling unstable. If one of you spreads out a lot, or a pet joins you nightly, the UK super king adds further breathing room.
Should I get the Emma Original Lite in a UK double or a UK king?
The UK king is 15cm wider than the UK double and 200cm long rather than 190cm. If you share the bed and either of you is tall, wakes easily, or gets up at a different time, the UK king is the safer pick, provided your room meets the minimum we suggest.
What room size do I need for a UK king Emma Original Lite?
We suggest allowing at least 2.7m x 2.9m, and closer to 3.2m x 3.2m if you want space to walk around both sides with bedside tables in place. New build master bedrooms can be tighter than they first appear once wardrobes go in, so measure the usable floor rather than the room.
Is the Emma Original Lite king long enough for tall sleepers?
At 200cm (the UK king measures 5ft x 6ft 6in), it's a better fit for anyone around six foot than the 190cm-long UK single, small double or double. If length is your main reason for upgrading, the UK king gets you there without the extra width and room demands of a super king.
Where is the cheapest place to buy the Emma Original Lite in a UK king?
It varies, and often week to week. The prices shown on this page are updated as retailers change them, so compare the retailers listed here rather than assuming Emma's own site is cheapest. Watch that you're comparing the UK king specifically, since the EU king is a different size.
