Luxe super king mattresses measure 180 × 200 cm — a full single bed’s width for each sleeper, and the largest standard size made in the UK. Hand built in our British workshop across every collection, with the same 100 night trial and 10 year warranty as every other size.
A UK super king mattress measures 180 cm wide by 200 cm long (6'0" × 6'6"). Shared between two people that is 90 cm each — the full width of a standard single bed per sleeper.
It is the largest standard UK size, and the practical limit for most homes: not because of the mattress, but because of the room and the route in. If you have the floor space and a straightforward staircase, nothing else comes close for couples, for families who co-sleep, or for anyone who has simply had enough of being crowded.
This is the size where measuring genuinely matters — both the room and every doorway, turn and staircase on the way to it.
Every collection we build is available at 180 × 200 cm, at every firmness level from extra soft to rock hard.
Answer a few quick questions about your sleep style, body type and what matters most to you — we’ll match you to the Luxe mattress built for the way you sleep, in 180 × 200 cm.
Take the mattress quizAll 13 mattresses below are made to order in 180 × 200 cm, hand built in our UK workshop, with free 2 man delivery and a 100 night trial.
Super king is a genuine step change rather than an incremental upgrade. Here is what you actually gain.
90 cm per sleeper — the same width as a standard single bed, each. Partner disturbance largely stops being a factor.
The size families choose when a child ends up in the bed at 3am, without anyone sleeping on the edge.
Width plus pocket springs and motion isolation means movement on one side barely registers on the other.
Every mattress is hand built in our British workshop in the size you order — nothing is cut down from a larger blank.
Hybrid, memory foam, pocket sprung, latex and orthopaedic are all available in this size, at every firmness level.
Sleep on it at home. Refund to night 60, exchange to night 100, and we collect free of charge.
Whatever size you choose, every Luxe mattress is built from the inside out with materials chosen for support, airflow and a 10 year plus lifespan.
Stretch-knit or Tencel fabric with an antimicrobial finish for a hygienic, breathable sleep surface.
Memory or gel-infused foam cushions the hips and shoulders while the core does the supporting.
Reflex and PU foams above 35 kg/m³ stop the comfort layer bottoming out and add years of life.
Individually pocketed springs respond independently to each sleeper for proper alignment.
Firmer perimeter springs give edge-to-edge support so you use the whole mattress.
OEKO-TEX Standard 100 fabrics, FIRA sleep tested, made in Great Britain under the NBF Code of Practice.
Sizes are the mattress itself, not the bed frame. Allow roughly 60–75 cm of walking space on each side you need to get past.
