Layer Details
Advanced e-Fibre
A super soft top layer that's described as award-winning for luxury comfort and breathability. It gives the firm mattress a softer surface to lie on, with airflow built in.
Rebound e-Fibre
A cushioning layer that provides contour support. It sits beneath the top layer and helps the surface follow your shape a little, so the firm feel isn't completely unyielding.
e-Spring core
A deep e-Spring core forms the base of the mattress. It provides the supportive foundation behind the firm feel, and the construction is foam-free.

Key benefits
- Room for two on a budget: You get 67.5cm each for two people sharing, which means a couple gets a firm, spring-based surface without the outlay a king usually demands.
- Fits typical UK bedrooms: The 135 x 190cm footprint suits most rooms; we suggest at least 2.6m x 2.8m, which still leaves space for bedside tables on both sides.
- Easier to get upstairs: At 18cm deep this double is slimmer and lighter than most hybrids, which helps when you're turning it up the stairs of an older terrace.
- Firm support across the width: The firm rating means neither sleeper sinks towards the middle, useful in a shared size where a softer budget mattress can dip under the heavier partner.
- Simple to dress: Standard double sheets and a 200 x 200cm duvet fit, both stocked everywhere at every price point, handy if you're kitting out a whole home at once.
This size suits you if...
You're a couple wanting the classic shared size in a room where a king would feel cramped, you're furnishing a first flat or a whole house and need a sensible firm double without spending much, or you're setting up a guest room that visiting couples will actually be comfortable in.
Consider another size if...
You and your partner both like space and your room can take a bigger bed. The UK king is 15cm wider and 10cm longer; we suggest at least 2.7m x 2.9m for it, and this mattress comes in that size.

FAQ's
Is the Jay Be Benchmark S1 double big enough for two adults?
It works for most couples. At 135 x 190cm you get 67.5cm each for two people sharing, and the firm feel keeps the surface stable so you're less likely to roll towards each other. Broad-shouldered partners or restless sleepers may prefer the UK king, which is 15cm wider and 10cm longer.
What room size do I need for the Benchmark S1 in a UK double?
We suggest at least 2.6m x 2.8m. That allows you to walk around the bed and fit bedside tables on both sides, which matters for a couple sharing every night. If your room is smaller, the UK small double is 15cm narrower and the same length; we suggest at least 2.4m x 2.8m for that size.
Is the double Benchmark S1 easy to move into an upstairs bedroom?
Easier than most doubles. At 18cm deep it's slimmer and lighter than the typical hybrid, so turning it up the stairs of an older terrace or across a tight new build landing is less of a struggle. Doubles are still a two-person carry, so have someone on the other end.
Is the Jay Be Benchmark S1 double a good guest room mattress?
It's a sensible choice. A double accommodates visiting couples as well as solo guests, and the firm surface suits occasional use where you can't tailor the feel to one person. The 135 x 190cm footprint leaves space in a second bedroom that also has to hold a wardrobe and drawers.
Should I get the Benchmark S1 in a double or a king?
Go by your room and your budget. The UK double fits comfortably where the UK king, 15cm wider and 10cm longer, would dominate, and it costs less across every retailer. If you both want more personal space and can allow at least 2.7m x 2.9m, the UK king is the better long-term buy. Compare the retailers listed on this page for current prices.
