Layer Details

Comfort Layer
100% Yorkshire wool blended with silky-smooth mohair, chosen for its springy, soft and resilient qualities. In practice that means a comfortable surface that recovers its shape rather than developing dips quickly.

Additional Comfort Fillings
Fine cotton, flax and hemp fibres that are naturally breathable and wick away moisture. You should feel noticeably cooler through the night than on a foam-heavy mattress.

Support System
Over 9,000 individual pocket springs encased in breathable fabric, each reacting independently. This gives tailor-made support and pressure relief, with less motion transfer if you share the bed.

Key benefits

Key Benefits of the Harrison Spinks Alwoodley 9750 Pocket Double Mattress

  • The classic shared size: At 135 x 190cm, the UK double is the long-established couples' size, wide enough to share without dominating a typical British bedroom.
  • Space for two, stated plainly: Two people sharing get 67.5cm each, which works well for couples who sleep close, though restless pairs may notice the limit.
  • Pocket springs matter more at this width: Over 9,000 independent pocket springs mean a partner turning over on their 67.5cm disturbs you less than a shared open coil would.
  • Natural fillings for two warm bodies: Yorkshire wool, mohair, cotton, flax and hemp breathe and wick moisture, useful when two sleepers share heat in a 135cm width.
  • Room to keep both bedside tables: We suggest a minimum room of 2.6m x 2.8m, which in most bedrooms still leaves space for a table on each side.
  • Bedding is easy and everywhere: Standard double sheets and a 200 x 200cm double duvet fit, stocked at every price point, though check sheet depth against the 29cm profile.

Who should buy the Harrison Spinks Alwoodley 9750 Pocket Double Mattress?

This size suits you if...

You're a couple in a typical UK bedroom where a bigger bed would crowd the walkways, or you sleep alone and want proper stretching room, perhaps with a dog or cat claiming a corner. It also suits a guest room that regularly hosts visiting couples, since the UK double is the size most guests expect and bedding for it is cheap and easy to find.

Consider another size if...

You and your partner both sleep restlessly, or one of you is tall, since the UK double is 15cm narrower and 10cm shorter than the UK king. We'd recommend the UK king instead, allowing a room of at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Double

Is the Harrison Spinks Alwoodley 9750 double big enough for a couple?

For most couples, yes. You get 67.5cm each for two people sharing, and the 9,000-plus pocket springs move independently, so one of you shifting about disturbs the other less than on a connected spring unit. If either of you sprawls, or you're both broad-shouldered, the UK king's extra 15cm of width is the safer choice.

What room size do I need for the Alwoodley 9750 in a UK double?

We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That's our guidance rather than the manufacturer's, and it assumes you want to walk around the bed and open drawers without shuffling sideways. In most rooms that size, bedside tables on both sides remain realistic.

Should I get the Alwoodley 9750 in a UK double or a UK king?

The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the UK double if your room is around the 2.6m x 2.8m minimum, or if you want space left for other furniture. Choose the UK king if the room allows at least 2.7m x 2.9m and you'd value the extra width more than the floor space.

Will a double Alwoodley 9750 fit up the stairs in an older house?

A 135 x 190cm pocket sprung mattress with natural fillings won't fold or roll the way foam can, so measure any turning stairs in older terraces and tight landings in new builds before ordering. Check the narrowest point of the route, including door frames, against the mattress dimensions of 4ft 6in x 6ft 3in.
