Key benefits

Key Benefits of the TheraPur ActiGel Arctic 3000 Combination Small Double Mattress

  • Room to spread out on your own: At 30cm wider than the UK single, you can stretch an arm out or sleep at an angle on firm, flat support without finding the edge.
  • Fits where a double would crowd: It's 15cm narrower than the UK double, which can decide whether a wardrobe or bedroom door still opens fully past the frame.
  • A cooler surface in a small room: The graphite-infused ActiCool+ cover is designed to keep the surface cooler, which may help if a compact bedroom or loft conversion gets warm at night.
  • Calmer nights when guests share: Pocket and micro springs absorb motion, so when a couple stay for a weekend, one person turning over should disturb the other less.
  • Bedding is easy to find: 4ft is a standard UK size, so small double fitted sheets are simple to buy and a standard double duvet fits on top.

Who should buy the TheraPur ActiGel Arctic 3000 Combination Small Double Mattress?

This size suits you if...

You sleep alone, like firm support and want room to spread out without giving up the floor space a UK double takes, or you're furnishing a guest room or holiday let where couples stay for the odd weekend rather than every night.

Consider another size if...

You share the bed with a partner every night. We'd recommend the UK double instead, which gives 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 TheraPur ActiGel Arctic 3000 UK small double fit in a box room?

We suggest allowing at least 2.4m x 2.8m for a UK small double. The mattress itself is 120 x 190cm, but frames add to that, so measure the frame's full footprint and check the door still swings clear, then compare the retailers listed on this page.

Is a UK small double TheraPur ActiGel Arctic 3000 big enough for two?

For occasional nights, yes, and the pocket and micro springs help limit motion when one of you moves. For sharing every night it's tight. The UK double gives 67.5cm each for two sharing and the UK king gives 75cm each, so couples will be more comfortable sizing up.

What sheets fit a TheraPur ActiGel Arctic 3000 small double?

Small double (4ft) fitted sheets fit, with a standard double duvet on top. Therapur doesn't publish a depth for this mattress, so ask the retailer about depth before buying deep-pocket sheets, or check the pocket size against the mattress once it arrives.

Is the TheraPur ActiGel Arctic 3000 UK small double long enough for a tall adult?

It's 190cm long, the same length as the UK single and UK double, so moving up to a UK double adds width but no length. If you need more legroom, the UK king is 10cm longer than the UK small double, and we suggest at least 2.7m x 2.9m for the UK king.

Is a small double ActiGel Arctic 3000 a good choice for a teenager?

It can be, if your teenager has outgrown a single and likes a firm feel. The UK small double is 30cm wider than the UK single yet narrower than a UK double, so a modest bedroom keeps space for a desk. Lighter teens who like to sink in may find the firm rating hard going.
