Key benefits

Key Benefits of the Harrison Spinks Heaven 21500 Medium Double Mattress

  • Room to share without dominating the bedroom: We suggest a minimum room of 2.6m x 2.8m, which leaves space for a wardrobe and drawers in a typical UK double bedroom.
  • 67.5cm each for two people sharing: That's the standard couples' allowance, and the pocket springs mean your partner turning over is far less likely to disturb you within it.
  • Bedside tables on both sides, usually: In most rooms around the 3m x 3m norm, a 135cm wide bed still allows a table each, which a wider size often doesn't.
  • Easy to dress: Double sheets and 200 x 200cm double duvets are stocked everywhere at every price, useful when this mattress has already taken a large share of the budget.
  • Medium tension suits a sharing couple: A forgiving middle ground for two people with different sleeping positions, though front sleepers may find it slightly soft.

Who should buy the Harrison Spinks Heaven 21500 Medium Double Mattress?

This size suits you if...

You share the bed every night and your bedroom sits around the typical UK size, where a king would leave you squeezing past the footboard. It also suits a solo sleeper who wants proper room to spread out, or a pet claiming a corner, without giving the whole room over to the bed. Guest rooms that host visiting couples are well served by this size too.

Consider another size if...

You and your partner both like space and your room measures at least 2.7m x 2.9m. In that case we'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double.

FAQ's

Frequently Asked Questions About the UK Double

Is the Heaven 21500 in a UK double big enough for a couple?

For most couples, yes. You get 67.5cm each for two people sharing, and because pocket springs move independently, you feel less of your partner's movement in that space. If either of you is broad shouldered or a restless sleeper, the UK king adds 15cm of width and 10cm of length.

What room size do I need for the Heaven 21500 double?

We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That guidance is ours rather than Harrison Spinks', and it assumes you want to open drawers and walk round the bed without shuffling sideways. Bedside tables on both sides are usually still possible at this size.

Should I buy the Heaven 21500 in a double or a king?

It mostly comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, and we suggest at least 2.7m x 2.9m for the UK king. If your bedroom clears that with space for furniture, the extra width is a genuine comfort gain for two; if not, the UK double is the sensible pick.

Is the double Heaven 21500 longer than the single?

No, the UK double and the UK single are the same length. The difference is width: the UK double is 45cm wider than the UK single, which is what turns it from a one-person bed into a shared one. Anyone over about 6ft 3in outgrows both lengths equally.

What bedding fits the Heaven 21500 in a double?

Standard UK double bedding: double fitted sheets for the 135 x 190cm mattress and a 200 x 200cm double duvet. Because the double is the most common British size, you'll find bedding for it in every shop and at every price point, which helps if you're furnishing a whole home at once.
