An ultra-durable, 100% recyclable filling that Dreams says feels like a million tiny springs. It gives a springy, hard-wearing comfort layer on top of the coils.
Open coil springs
Hourglass-shaped coils that promote airflow and full-body support. You get a firm, supportive base that lets air move through the mattress.

Key benefits
- Room to ignore a restless partner: With 90cm each, a partner who turns over all night is simply further away, and distance helps more than any comfort layer can.
- Space for a small visitor: When a child wanders in after a bad dream, a UK super king leaves both adults a usable strip of firm mattress rather than a sliver at the edge.
- Steady support for dogs on the bed: A firm open coil base under a whole 6ft x 6ft 6in surface suits households where a large dog sleeps on the bed every night.
- Fills a big master bedroom properly: In a period property or a large master, a UK super king looks in proportion where a UK king can seem a little lost against the wall.
- Generous gain over a UK king: It's 30cm wider than a UK king at the same length, so each sleeper gains 15cm without the bed getting any longer.
This size suits you if...
You share with a partner who fidgets, kicks or gets up often, and you want real distance between you. It also suits you if children or a large dog regularly end up in the bed and you still want a firm, traditional spring mattress that leaves everyone a proper share.
Consider another size if...
Your bedroom measures under our suggested minimum of 3m x 2.9m. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Carty super king big enough for two adults and a child?
For occasional night-time visits, yes. A UK super king gives two adults 90cm each, so a small child can squeeze in without anyone hanging off the edge. As a nightly arrangement it gets snug as children grow, but it's the roomiest standard UK size, and the firm surface stays even across the full 180cm width.
What size bedroom do I need for a Dreams Workshop Carty super king?
We suggest at least 3m x 2.9m for a UK super king, and around 3.5m x 3.2m feels comfortable once you add bedside tables on both sides. In a loft conversion, check which wall gives you full head height at the pillow end, because the slope often decides where a 180cm wide bed can go.
How much more room does the Carty super king give than the king?
The UK super king is 30cm wider than the UK king and the same length, which works out at 15cm more each for two people sharing. Against the UK double, the gain is 22.5cm more each. If your room is tight, the UK king needs at least 2.7m x 2.9m.
Will a super king mattress get up my stairs and through the bedroom door?
Measure first. A UK super king is 180 x 200cm and the Carty is 22cm deep, so check the tightest landing turn, the bedroom door width and which way that door swings into the room. Once you're confident it fits, compare the retailers listed on this page.
What bedding fits the Carty in a UK super king?
You'll need super king fitted sheets with enough depth for a 22cm mattress, plus a 260 x 220cm duvet. Super king bedding usually costs more than king sets, so factor that in if you're moving up from a smaller bed and replacing everything at once.
