Layer Details
- Cover. A knitted fabric cover, which gives a soft-touch sleep surface against the skin.
- Advanced e-Fibre®. An award-winning fibre comfort layer designed for luxury comfort and breathability. Because it's fibre rather than foam, it allows air to move more freely, which means less heat building up overnight.
- Rebound e-Fibre®. A resilient fibre layer that provides contour support, shaping to your body while springing back into place.
- Micro e-Pocket™ springs. A layer of small pocketed springs that move independently, which means the mattress adapts to your shape and weight rather than pushing back uniformly.
- e-Spring™ core. The main spring core, providing the deep support that keeps your spine aligned.

- The traditional size for two: At 135 x 190cm, the UK double is the long-standing shared size, giving 67.5cm each for two people sharing.
- Firm support helps when sharing: The firm tension keeps the surface stable, which means you're less likely to roll towards a heavier partner in the night.
- Fibre layers for two warm bodies: Two people generate more heat than one, and the fibre comfort layers let air move more freely than memory foam would.
- Fits typical UK rooms: We suggest at least 2.6m x 2.8m, which leaves space for a wardrobe and drawers in most second bedrooms and first flats.
- Easy to dress: Double sheets and duvets are sold everywhere at every price point, handy if you're furnishing a whole home on a stretched budget.
This size suits you if...
You share the bed most nights and want the standard couples' size without giving a UK king's worth of floor to the mattress, your room sits around the 2.6m x 2.8m minimum we suggest, or you sleep alone, perhaps with a dog or cat claiming a corner, and want firm support with room to spread out.
Consider another size if...
You both toss and turn and your bedroom comfortably exceeds 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.

What are the dimensions of the Jay-Be Benchmark S5 in a UK double?
The UK double measures 135 x 190cm, or 4ft 6in x 6ft 3in. It's 20cm deep, which is slimmer than some deep-fill hybrids, so a standard double fitted sheet will tuck in without a struggle.
How much space does each person get on the UK double Benchmark S5?
Two people sharing get 67.5cm each. That's fine for couples who sleep close, and the firm tension means movement transfers less than on a softer mattress. If either of you sprawls, the UK king adds 15cm of width and 10cm of length.
Will the UK double fit a bedroom with bedside tables on both sides?
Usually, yes. We suggest at least 2.6m x 2.8m for a UK double, and around 3m x 3m is the comfortable norm. At the minimum you'll fit a slim table each side; the extra room in a 3m-wide bedroom makes both tables and walking space easy.
Is the UK double Benchmark S5 a good choice for a guest room?
It's a sensible pick. The UK double accommodates visiting couples, the firm tension suits a wide range of occasional sleepers, and the fibre layers stay cooler than foam for guests unused to your heating. The prices shown on this page update as retailers change them, so compare before you buy.
Should I choose the UK double or the UK small double for this mattress?
The UK double is 15cm wider than the UK small double; both are the same length. For two adults sharing every night, that width matters. Pick the UK small double only if your room is tight: we suggest at least 2.4m x 2.8m for it, against 2.6m x 2.8m for the UK double.
