Layer Details
- Infused Embroidered Cover. The embroidered cover contains 2cm of bamboo and charcoal infused memory foam, which means the comfort starts before you reach the layers beneath. It adds a soft initial feel to the sleeping surface.
- Charcoal & Bamboo Memory Foam. A layer of charcoal and bamboo infused memory foam designed to keep you at a comfortable temperature and reduce odours. You get the contouring feel of memory foam with less of the warmth.
- 1000 Encapsulated Pocket Springs. A comfort layer of 1,000 encapsulated pocket springs sits above the main support layer. It adds a responsive, slightly springy feel while keeping air moving through the mattress.
- High Density Support Foam. A layer of Reflex foam provides additional support on top of the main spring layer. It acts as a transition, so you don't feel the springs directly.
- 16cm Encapsulated Pocket Springs. The main support layer uses 16cm encapsulated pocket springs, which Otty says gives the mattress its medium-firm feel. Because each spring moves independently, motion transfer is kept to a minimum.
- Airflow Side Support. Reinforced sides with airflow technology give you an edge-to-edge sleeping surface, so you can use the full width of the bed. The design also helps with temperature regulation.
- High Density Base Foam. A high density foam base gives the whole mattress a solid foundation. It's there to help the mattress keep its shape over the years.

- A shared size that fits most rooms: At 4ft 6in x 6ft 3in, the UK double fits comfortably in rooms where a UK king would leave little space to walk around.
- Springs that hide a partner's movement: Encapsulated pocket springs move independently, so at 67.5cm each for two people sharing, a restless partner is less likely to wake you.
- Full width you can actually use: Reinforced airflow side supports give an edge-to-edge sleeping surface, which matters more on a double where every centimetre of shared width counts.
- Cooler sharing: Two bodies warm a bed faster than one, and the bamboo and charcoal infused foam is designed to shed that heat rather than trap it.
- Room left for bedside tables: Allow at least 2.6m x 2.8m and most bedrooms will still take a table on each side, something a UK king often rules out.
This size suits you if...
You share the bed every night and want the traditional couples' size rather than the biggest one your room could theoretically take, or you sleep alone and like space to spread out. It also suits a guest room that regularly hosts visiting couples, since the medium-firm 7/10 feel works for most sleepers without knowing who's arriving.
Consider another size if...
You're a couple with the room to go bigger, or either of you is tall, since the UK double is 15cm narrower and 10cm shorter than the UK king. We'd recommend the UK king instead for a noticeably easier share.

Is the Otty Pure Pro Hybrid UK double big enough for a couple?
Yes, for most couples. You get 67.5cm each for two people sharing, and the encapsulated pocket springs respond to each sleeper independently, so you feel less of a partner turning over. If one of you sleeps in a sprawl, or you're both broad-shouldered, the UK king's extra 15cm of width is the more comfortable call.
What size room do I need for the Otty Pure Pro Hybrid in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That usually leaves space for bedside tables on both sides plus a wardrobe, which is exactly why the UK double remains the default in typical UK bedrooms where a UK king would dominate.
Should I choose this mattress in a UK double or a UK king?
It comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, so taller sleepers and couples who want more personal space should size up if the room allows. If going bigger would squeeze out your furniture, the UK double is the better balance of bed against floor space.
What bedding fits the Otty Pure Pro Hybrid UK double?
Standard double sheets and a 200 x 200cm double duvet, both stocked everywhere at every price. One practical point: this mattress is 27cm deep, so check the fitted sheet's stated depth before buying, as shallower double sheets can ping off the corners overnight.
How does the UK double compare to the UK small double for this mattress?
The UK double is 15cm wider than the UK small double, and the two are the same length. For one person that extra width is a nice-to-have. For two sharing every night it's the difference between a workable bed and a cramped one, so we'd steer couples towards the UK double where the room allows.
