Key benefits

Key Benefits of the Sleepeezee Tranquil 1600 Small Double Mattress

  • Space to stretch out on your own: At 30cm wider than a UK single, the UK small double lets you sleep with your knees drawn up or roll over without finding the edge.
  • Fits a compact double bedroom: Because it is 15cm narrower than a UK double, the UK small double can leave just enough floor for a door to clear or a wardrobe to open.
  • Support wherever you settle: Individual pocket springs react to the spot you are lying on, so sleeping off-centre on a wider solo bed should still feel evenly supported.
  • Sensible for occasional couples: In a spare room where a couple stays now and then, the independent springs usually limit how much one person feels the other turning over.
  • Easy to kit out: The UK small double is a standard 4ft size, so you shouldn't struggle to find a frame or fitted sheets to match.

Who should buy the Sleepeezee Tranquil 1600 Small Double Mattress?

This size suits you if...

You sleep alone and a UK single has started to feel cramped, your bedroom is compact but still meets our suggested minimum of 2.4m x 2.8m, or the bed is going in a spare room where a couple stays only once in a while.

Consider another size if...

Two of you will share the bed every night. We'd recommend the UK double instead, which gives 67.5cm each; allow at least 2.6m x 2.8m for the UK double.

FAQ's

Frequently Asked Questions About the UK Small Double

Will the Sleepeezee Tranquil 1600 UK small double fit in a box room?

For a UK small double we suggest a room of at least 2.4m x 2.8m. In a box room, measure where the door swings and where you need to stand to open drawers, because the width of the bed decides whether both still work. If your room falls short, the UK single needs at least 2.1m x 2.8m.

Is a UK small double Tranquil 1600 a good upgrade for a teenager?

Often, yes. The UK small double is 30cm wider than a UK single but the same length, so a teenager gains real sideways room while the bed takes up no extra length in the room. It suits a growing sleeper who sprawls, as long as the bedroom meets our suggested minimum of 2.4m x 2.8m.

Is the Tranquil 1600 small double long enough for a tall person?

The UK small double is 190cm long, or 6ft 3in, so very tall sleepers may find their feet near the end. If length matters more than floor space, the UK king is 10cm longer, although it is also 30cm wider and we suggest at least 2.7m x 2.9m for the UK king.

Can a couple sleep on the Sleepeezee Tranquil 1600 small double as a guest bed?

For a weekend visit, yes. The independent springs help reduce how much movement travels across the bed, which makes a short stay more comfortable. For nightly sharing it gets tight, and the UK double, which gives 67.5cm each, would be the kinder choice for a couple.

Does the Tranquil 1600 small double suit a loft conversion bedroom?

It can. Being 15cm narrower than a UK double, the UK small double leaves a little more usable floor beside the bed where a sloping ceiling cuts into headroom. Check you can stand upright on the side you get in and out, and that the room still meets our suggested minimum of 2.4m x 2.8m.
