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.

- Real space for one: At 30cm wider than the UK single, you can starfish, shift position or share with a book and a laptop without hanging over the edge.
- Fits where a double won't: Being 15cm narrower than the UK double, it can be the difference between a door that clears the bed and one that doesn't.
- Full-width sleeping surface: Reinforced airflow side supports mean the edges are usable, which matters more on a 120cm mattress where every centimetre of width counts.
- Cool for a snug room: Smaller bedrooms often run warmer, and the bamboo and charcoal infused foam is designed to hold less heat than standard memory foam.
- Copes with occasional sharing: Encapsulated pocket springs move independently, so on nights when two of you share, one person turning is less likely to wake the other.
This size suits you if...
You're a solo adult who has outgrown a single and wants space to sprawl, your bedroom, box room or loft conversion can't fit a 135cm double with walking room to spare, or you're furnishing a guest room where couples stay a few weekends a year rather than every night. Allow at least 2.4m x 2.8m of floor space and it should sit comfortably.
Consider another size if...
You share the bed every night, because 120cm is snug for two adults long term. We'd recommend the UK double instead, or the UK king if your room allows a 150cm frame.

Is the Otty Pure Pro Hybrid small double big enough for a couple?
For occasional nights, yes. It measures 120 x 190cm, and the reinforced side supports mean you can both use the full width right to the edge. As an every-night bed for two adults it's tight, and the UK double, 15cm wider, is the better long-term choice.
What size room do I need for a small double mattress?
We suggest allowing at least 2.4m x 2.8m for the Otty Pure Pro Hybrid in a UK small double. That leaves enough space to walk around the bed and open drawers. If your room falls short of that, a UK single may be the more practical fit.
How much wider is a small double than a single?
The UK small double is 30cm wider than the UK single, at 120cm across rather than 90cm. That extra width is the whole point for a solo sleeper: room to turn and stretch without the footprint of a full UK double, which is 15cm wider again.
Will the small double suit a teenager moving up from a single?
It's a common upgrade. A teenager gets adult-level space to sleep and lounge, while the 120cm width leaves more floor free than a UK double would. The medium-firm 7/10 feel suits most sleepers, though a very light side sleeper may find it slightly firm at the shoulder.
Is the Otty small double a good choice for a guest room?
Yes, provided guests are occasional rather than resident. Solo visitors get generous space, and couples can share comfortably for a weekend, helped by pocket springs that keep motion transfer low. If couples will stay regularly and the room allows, the UK double is worth considering instead.
