Key Benefits of the Rest Assured Harris Ortho Pocket 1400 Small Double Mattress

  • Room to spread out alone: At 30cm wider than the UK single, you can sleep on your back with arms out or turn over freely on the firm surface without hitting an edge.
  • Fits smaller double rooms: Being 15cm narrower than the UK double, it leaves a little more floor beside the bed, which helps when a door or wardrobe swings close to the frame.
  • Same length as a double: At 4ft x 6ft 3in, the UK small double matches the UK double for length, so you lose width only, never legroom.
  • Firm support for a single sleeper: A firm pocket spring surface with nobody else's weight beside you means the mattress stays flat and even under your back through the night.
  • Guest room flexibility: Visiting couples can manage a night or two, and the wire edge border helps the sides hold their shape when two people use the full width.

Who should buy the Rest Assured Harris Ortho Pocket 1400 Small Double Mattress?

This size suits you if...

You sleep alone but like to stretch out, your bedroom can't comfortably take a standard double, or you're setting up a guest room where couples stay now and then but nobody sleeps every night.

Consider another size if...

You share the bed every night and both want room to move. We'd recommend the UK double instead, giving 67.5cm each for two sharing; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's

Frequently Asked Questions About the UK Small Double

Will a UK small double Harris Ortho Pocket 1400 fit in my bedroom?

We suggest a room of at least 2.4m x 2.8m for a UK small double, which leaves space to walk round the bed and open drawers. In a loft conversion with a sloping ceiling, check you still have standing room on the side you get in, as the mattress itself measures 120 x 190cm.

Is the Harris Ortho Pocket 1400 small double big enough for two people?

For occasional stays, yes, and the firm surface means neither of you rolls into a dip. For nightly sharing it gets tight. The UK double gives 67.5cm each for two sharing, so most couples who share every night would be more comfortable in a UK double.

Should my teenager move from a single to a UK small double mattress?

If they've outgrown a single, the UK small double is 30cm wider and the same length, so they gain width without losing legroom. It needs a little more floor, though: we suggest at least 2.1m x 2.8m for a UK single and 2.4m x 2.8m for a UK small double.

What size sheets and duvet fit a UK small double Harris Ortho Pocket 1400?

Use small double (4ft) fitted sheets with a standard double duvet. The mattress is 27cm deep, so check the fitted sheet's pocket depth covers that before buying, or the corners may keep slipping off.

Is the Harris Ortho Pocket 1400 small double long enough for tall sleepers?

It measures 190cm long, the same as the UK double. If you're tall and your feet already reach the end of a bed, the UK king is 10cm longer, although it's also 30cm wider and we suggest at least 2.7m x 2.9m for that UK king.
