Layer Details
- Sleep surface. A soft-knitted sleep surface treated with plant-based margosa and linseed oils, which is where the anti-allergy protection comes from. It sits directly against your bedding, so the treatment works where it matters.
- Comfort layer. Extra-soft Advance e-Fibre, deep-quilted for gentle cushioning. This gives the initial softness you feel when you first lie down.
- Comfort layers. Breathable, 100% foam-free open-structured comfort layers that allow air to circulate freely. If you tend to sleep hot, this is the layer doing the work to keep you cooler.
- Support core. A deep sprung core that distributes support evenly across the mattress. This is what keeps your spine aligned rather than letting you sink into a dip.

- A sensible width for sharing: At 135cm across, two people get 67.5cm each for two people sharing, enough for most couples who sleep fairly settled.
- Cooler with two in the bed: Two sleepers generate more heat than one, and the open-structured Advance e-Fibre layers let air move through rather than trapping warmth the way foam can.
- Fits typical UK bedrooms: We suggest allowing at least 2.6m x 2.8m, which most British doubles rooms manage while still leaving space for a wardrobe and drawers.
- Room for bedside tables on both sides: Because the UK double is 15cm narrower than the UK king, many rooms can still take a table each side, which matters when you both read or charge phones.
- An easy guest room choice: The anti-allergy sleep surface, treated with plant-based margosa and linseed oils, makes it a considerate pick for a spare room that hosts visiting couples.
This size suits you if...
You're a couple who wants the traditional shared size without giving your whole room over to the bed, you're kitting out a first flat where the bedroom also has to hold a wardrobe and drawers, or you're setting up a guest room that regularly sleeps two and want an allergy-friendly surface waiting for visitors.
Consider another size if...
You and your partner keep waking each other, or one of you is tall, since this size is 190cm long. The UK king would suit you better: it's 15cm wider and 10cm longer, and we suggest a room of at least 2.7m x 2.9m for it.

Is the Jay Be Pure Anti-Allergy mattress in a UK double big enough for a couple?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, which suits pairs who sleep reasonably settled. If either of you spreads out, moves a lot in the night, or shares with a pet claiming a corner, the extra 15cm of width in the UK king makes a noticeable difference.
What are the dimensions of the Jay Be Pure Anti-Allergy UK double?
It measures 135 x 190cm, which is 4ft 6in x 6ft 3in. That's the standard UK double footprint, so it fits any UK double bed frame and takes ordinary double sheets and a 200 x 200cm double duvet, all of which are stocked everywhere at every price.
Will a UK double Jay Be Pure fit in my bedroom?
We suggest allowing at least 2.6m x 2.8m of floor space, with around 3m x 3m the comfortable norm. That leaves you walking room on both sides and, in most rooms, space for bedside tables each side. It's our guidance rather than JAY-BE's, but it's a reliable starting point.
Should I get this mattress in a double or a king?
Choose the UK double if your room is on the smaller side or you want space left for other furniture. The UK double is 15cm narrower and 10cm shorter than the UK king, so sizing up buys real stretching room but needs at least 2.7m x 2.9m of floor space by our guidance.
