Key benefits

Key Benefits of the Sleepeezee Tranquil 1200 Double Mattress

  • Width you can use: Edge-to-edge encapsulated springs firm up the perimeter, which means the outer part of your 67.5cm feels about as supportive as the middle.
  • Less disturbance at close quarters: You lie nearer each other on a UK double, so 1,200 independently moving springs help stop a partner's turning from reaching your side.
  • Suits a typical main bedroom: We suggest a room of at least 2.6m x 2.8m, a little less than the 2.7m x 2.9m we suggest for the UK king.
  • Easy bedding: Double sheets and duvets are sold almost everywhere, which helps if you're kitting out a whole home at once and every purchase has to stretch.
  • A feel most couples share happily: The medium firm tension suits most pairs of sleepers, although a lightweight side sleeper may feel slightly more pressure at the shoulder.

Who should buy the Sleepeezee Tranquil 1200 Double Mattress?

This size suits you if...

You share a bed with your partner in an ordinary-sized main bedroom and still want space for bedside tables on both sides. It also suits you if you sleep alone and want enough width for a dog or cat to claim a corner without you losing yours.

Consider another size if...

Your room is smaller than our suggested 2.6m x 2.8m once the wardrobe and drawers are in. We'd recommend the UK small double instead, and we suggest at least 2.4m x 2.8m for the UK small double.

FAQ's

Frequently Asked Questions About the UK Double

How much space does each person get on a Sleepeezee Tranquil 1200 UK double?

Two people sharing get 67.5cm each on the UK double. That is snug but workable for most couples. Because the springs run edge to edge, you can sleep close to the side without feeling you might roll off. That makes the full 135cm usable rather than just the centre.

Will the Sleepeezee Tranquil 1200 UK double fit a second bedroom with a wardrobe and drawers?

Allow at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. In a smaller second bedroom or a first flat, measure the space you need to open wardrobe doors and pull out drawers. If that leaves the room short, the UK small double is 15cm narrower.

Is the Sleepeezee Tranquil 1200 UK double long enough for tall sleepers?

The UK double is 190cm long, which is 10cm shorter than the UK king. If either of you is tall and your feet already reach the end of your current bed, the UK king adds that length and gives 7.5cm more width each. We suggest at least 2.7m x 2.9m for the UK king.

Is a Sleepeezee Tranquil 1200 in a UK double a good choice for a guest room?

It suits a guest room well if visiting couples stay over, since the UK double gives two people 67.5cm each in a room of at least 2.6m x 2.8m. The medium firm feel suits most guests, though a lightweight side sleeper may find it a little firm.

UK double or UK small double Tranquil 1200 for one person and a pet?

The UK double is 15cm wider than the UK small double and the same length. If your dog or cat sleeps on the bed, those extra centimetres let the animal settle without pushing you towards the edge. The edge-to-edge springs also keep the side firm if you end up there anyway.
