Layer Details
Cover
A sumptuously soft natural cover, designed for enhanced breathability. In practice, that means air can move through the sleep surface rather than trapping heat against you.
Wool
Fully traceable Black Country wool that regulates temperature. Wool wicks moisture and buffers heat, so you should feel more even in temperature through the night.
Fibres
Recyclable, air-blown fibres that give the feel of a million micro springs. This creates a cushioned, responsive surface layer above the main spring unit.
Pocket Springs
Individually encased pocket springs that adapt to your body's movements to minimise disturbance to your partner, while supporting your back and hips. Each spring moves on its own, so one person turning over is less likely to jolt the other.

Key benefits
- 858 pocket springs across the double: Each spring moves on its own, which means a partner turning over at 3am is far less likely to wake you.
- Fits most UK bedrooms: At 135 x 190cm, the UK double leaves room for bedside tables on both sides in an average room where a UK king might not.
- 67.5cm each for couples: Two people sharing get 67.5cm each, enough for most couples who sleep reasonably close, though restless pairs may want more.
- Wool that helps two sleepers stay cool: Two bodies generate more heat than one, and the traceable Black Country wool wicks moisture, which means less clamminess on shared nights.
- Easier to manoeuvre than larger sizes: At 22cm deep and double-sided, the UK double is manageable to flip regularly and to carry up the turning stairs of an older terrace.
- Bedding is cheap and everywhere: Double sheets and a 200 x 200cm duvet are stocked at every price point, a small saving that adds up if you're furnishing a whole home.
This size suits you if...
You share the bed every night and your bedroom is a typical UK size, where a bigger mattress would leave no walking space, or you sleep alone and want proper room to stretch out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, since the medium tension is a safe middle ground for different tastes.
Consider another size if...
You and your partner both sleep restlessly, or one of you is over 6ft. The Elsham in a UK king gives you 15cm more width and 10cm more length; allow at least 2.7m x 2.9m of room for it.

FAQ's
How many springs does the Elsham have in a UK double?
The UK double contains 858 individually wrapped pocket springs, while Feather & Black lists the UK king at 1,000. Spring counts scale with surface area rather than with quality, so the support per square centimetre is comparable. Each spring compresses independently, so you feel your own weight cushioned rather than your partner's movements.
Is the Elsham double big enough for two adults?
For most couples, yes. You get 67.5cm each for two people sharing, which suits pairs who sleep fairly close and have an average-sized room. If either of you spreads out, or you're regularly joined by a child or pet, the Elsham in a UK king adds 15cm of width and 10cm of length.
What room size do I need for the Elsham in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. Our guidance, not the manufacturer's. That allows the door to open fully and gives space to walk round the bed. In a room that size you should still fit bedside tables on both sides, which a UK king often rules out.
Will the Elsham double fit up narrow stairs?
It stands a better chance than most. At 135 x 190cm and 22cm deep, the UK double is slimmer than many hybrids and noticeably easier to angle round a tight new build landing or the turning staircase of an older terrace than a UK king or UK super king would be. Measure your tightest turn before ordering.
Is the Elsham double a good choice for a guest room?
It's a sensible one. The UK double comfortably sleeps visiting couples, the medium tension is a middle ground most guests will get on with, and double bedding is inexpensive and easy to find. Being double-sided helps too: an occasionally used mattress flipped now and then should wear evenly for years.
