Layer Details
- Wool comfort layer. Sustainably sourced British wool that regulates temperature, which means you're less likely to overheat on a firm, dense mattress. Wool also handles moisture well, keeping the sleep surface feeling fresh.
- Cotton comfort layer. Natural cotton fibres that wick away moisture and help regulate body temperature. Paired with the wool above, this gives a breathable natural top rather than a synthetic one.
- eOlus™ recycled fibre pad. Made from recycled plastic bottles, with a vertical structure that's firmer than normal fillings. It sits next to the spring unit, adding support while soothing pressure points.
- ReActive™ 7-turn pocket springs. Hypnos' own pocket springs, designed to actively respond to your body shape for full-body personalised support. A dual heating treatment gives the springs memory and helps them retain their height over time.

- The classic shared size: At 135 x 190cm, the UK double is the long standing choice for two, and this firm build keeps both sleepers well supported across it.
- Fits a typical room: Allow at least 2.6m x 2.8m and you should still manage a wardrobe and bedside tables on both sides, which a UK king often prevents.
- Springs shared fairly: The 1,200 ReActive 7-turn pocket springs respond to each body individually, so a heavier partner settling in doesn't tilt the lighter one towards the middle.
- Cooler for two: Two people raise the temperature of any bed, and the wool and cotton layers help this firm surface stay noticeably fresher than synthetic-topped rivals.
- A flippable size: This mattress is double-sided and 28cm deep, and a UK double is about the largest size two people can still turn without a real struggle.
- Easy to dress: Double sheets and duvets are stocked everywhere at every price, useful if you're kitting out a whole home and the budget is stretched thin.
This size suits you if...
You share the bed every night and want proper firm support in a footprint that leaves your bedroom usable, you're furnishing a guest room that regularly hosts visiting couples, or you sleep alone and like space to stretch out, perhaps with a dog or cat that has claimed a corner. Back and front sleepers who want a genuinely firm surface will get on with it best.
Consider another size if...
You and your partner both like space, or one of you is a restless sleeper who needs room to move. The UK king is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m of floor space and we'd recommend it instead.

Is the Hypnos Marlow Ortho Deluxe UK double big enough for two people?
Yes, for most couples. Two people sharing get 67.5cm each, and the 1,200 pocket springs respond to each sleeper separately, so movement transfers less than the snug width might suggest. If either of you is tall, broad or a restless sleeper, the UK king, 15cm wider and 10cm longer, is the safer pick.
What room size do I need for the Hypnos Marlow Ortho Deluxe in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves space to walk round the bed and fit bedside tables on both sides, which matters when two of you are getting up at different times. In a smaller second bedroom or first flat, it should still leave room for a wardrobe and drawers.
Can two people flip the Hypnos Marlow Ortho Deluxe in a UK double?
Yes, and it needs doing regularly, as this is a double-sided mattress. At 135cm wide and 28cm deep it's a solid, dense thing to handle, but a UK double is manageable for two adults in a way the wider sizes are less so. Flipping it evens out wear, which is how double-sided mattresses reward the effort.
Will a UK double mattress fit up narrow stairs?
Usually, yes. At 135cm wide the UK double copes with the turning stairs of older terraces and tight new build landings better than a UK king would, though this mattress is 28cm deep and firm, so it won't fold round corners. Measure your tightest turn before ordering, and check the retailer's delivery terms for stair access.
Is the Marlow Ortho Deluxe better in a UK double or a UK king?
It depends on your room and how you sleep. The UK double suits couples who like sleeping close and rooms where a bigger bed would dominate. The UK king is 15cm wider and 10cm longer, and we suggest at least 2.7m x 2.9m for it. Compare the retailers listed on this page for current prices in both.
