Key Benefits of the Sealy Elevate Ultra Antuco Double Mattress

  • Fits a typical bedroom: At 135 x 190cm it fits a room of around 3m x 3m with bedside tables on both sides, and we suggest at least 2.6m x 2.8m.
  • Edges you can sleep on: With 67.5cm each on a UK double, the UniCased XT edge support helps the outer strip of the mattress hold its shape when one of you lies near it.
  • A middle ground for two: The medium grade sits between soft and firm, which makes it an easier compromise when two people with different tastes share one UK double.
  • Warmth from two sleepers: Two people generate more heat in a shared bed, and the SmarTex Plus cover, made with Tencel fibres, is designed to regulate temperature.
  • Bedding is easy to find: Standard double sheets fit and a 200 x 200cm double duvet covers it, so you can probably reuse the bedding you already own.

Who should buy the Sealy Elevate Ultra Antuco Double Mattress?

This size suits you if...

You share a bed with a partner in an average UK bedroom and want room left for bedside tables, or you sleep alone in a second bedroom or first flat and want space to stretch out without the bed crowding the wardrobe and drawers.

Consider another size if...

You and your partner both sprawl, or one of you is tall, because 67.5cm each is snug. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Double

Is a UK double Sealy Elevate Ultra Antuco big enough for two people?

For most couples, yes, although it is a close fit. You each get 67.5cm of width. The UK king gives 7.5cm more each and is 10cm longer, so if either of you sleeps starfish-style or is tall, sizing up to the UK king will feel noticeably less cramped.

What size bedroom do I need for a UK double Sealy Elevate Ultra Antuco?

We suggest at least 2.6m x 2.8m. A room closer to 3m x 3m is more comfortable, because it leaves space for a bedside table on each side and lets you walk round the bed. In a smaller room, measure the wall where the bed will go before you order.

Will a UK double mattress fit up a narrow or turning staircase?

The UK double measures 4ft 6in x 6ft 3in and this mattress is 34cm deep, so a turning staircase in an older terrace or a tight new build landing can be awkward. Measure the narrowest turn against the 135cm width first, then compare the retailers listed on this page.

Is the Sealy Elevate Ultra Antuco double a good choice for a guest room?

It suits a guest room well if you host couples, because 67.5cm each is fine for a few nights and the medium grade is a middle ground most guests can sleep on. It also leaves more floor space in a spare room than a UK king would.

Should I choose a UK double or UK king Sealy Elevate Ultra Antuco?

Choose by room size and how you sleep. The UK king is 15cm wider and 10cm longer, and we suggest at least 2.7m x 2.9m for it, compared with 2.6m x 2.8m for the UK double. If your room is tight, the UK double keeps space around the bed.
