Layer Details
- Cover. An in-house woven cover made without FR chemicals, meeting fire safety standards naturally. That means a healthier sleep environment without chemical treatments.
- Wool. A layer of British wool gives a plush, sumptuous sleeping surface. Wool also regulates temperature well, which helps if you tend to sleep warm.
- Cotton, Hemp and Flax blend. This blended layer wicks away moisture, which means the surface stays feeling fresher through the night.
- Hemp and Ecotex. Hemp and strong Ecotex fibres complete the comfort layers, adding durability and structure beneath the softer fillings.
- Micro springs. Layers of 2500 micro springs sit beneath the fillings, providing extra bounce that adapts to your body shape.
- Pocket Springs. The base layer holds 1000 Cortec™ Quad Revolution® pocket springs, with each dual spring in a cloth pocket and secured in groups of four. This gives independent, targeted support and helps limit partner disturbance.

- Room to share without dominating the bedroom: At 135 x 190cm, this size gives a couple a proper shared bed while still allowing bedside tables on both sides in a typical UK room.
- 67.5cm each for two sharing: That's the width per sleeper in a UK double, and the pocket springs move independently, so one of you turning over shouldn't wake the other.
- Natural fillings that suit close-quarters sleeping: Two bodies generate more heat than one, and the wool, cotton, hemp and flax layers wick away moisture, which means the surface stays cooler than foam.
- Easy to dress and furnish around: Double sheets and 200 x 200cm duvets are stocked everywhere at every price, handy if you're kitting out a whole home on a stretched budget.
- A sensible footprint for smaller rooms: We suggest allowing at least 2.6m x 2.8m of floor space, which most second bedrooms and first flats can manage once a wardrobe is in.
This size suits you if...
You share the bed every night and want the traditional couples' size that still leaves walking room, you're furnishing a first flat or a whole house and need a bed that fits alongside a wardrobe and drawers, or you sleep alone and like space to spread out, perhaps with a dog or cat claiming a corner.
Consider another size if...
You and your partner both toss and turn, or one of you is broad-shouldered, and 67.5cm each feels tight. The UK king is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m of room space and we'd recommend it instead.

Is the Harrison Spinks Bronze 3500 in a UK double big enough for a couple?
For most couples, yes. A UK double gives 67.5cm each for two people sharing, and the pocket springs are secured in cloth pockets in groups of four, which limits the movement you feel from a partner. If either of you sleeps restlessly or you're both taller or broader, the UK king's extra 15cm of width and 10cm of length may be worth the bigger footprint.
What room size do I need for the Bronze 3500 in a UK double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves enough clearance to open a wardrobe and fit bedside tables on both sides. If your room comfortably exceeds 2.7m x 2.9m, a UK king becomes an option; below our suggested minimum, the UK small double is 15cm narrower and worth considering.
Would the UK double Bronze 3500 work in a guest room?
It's a good fit. A UK double accommodates visiting couples, which a UK single or small double can't do comfortably, and its 135 x 190cm footprint usually leaves room for a wardrobe and drawers in a second bedroom. The soft to medium feel suits a range of guests, though anyone who insists on a firm surface may find it a little forgiving.
Is a UK double Bronze 3500 easy to get upstairs?
Being a pocket spring mattress with natural fillings, it doesn't arrive rolled in a box, so measure your access first. Turning stairs in older terraces and tight new build landings are the usual pinch points for a 135cm wide mattress. Check stairwell width and any awkward corners before ordering, and ask the retailer about their delivery arrangements for your property.
Should I get the Bronze 3500 in a double or a king?
It comes down to your room. The UK double suits most UK bedrooms and leaves space to move around the bed, while the UK king is 15cm wider and 10cm longer and needs at least 2.7m x 2.9m by our guidance. Couples with a generous master bedroom will appreciate the UK king; in a typical room, the UK double is the safer choice.
