Assessed from Otty's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This mattress suits you if you want the contouring of memory foam without the heat that often comes with it. The charcoal and bamboo infused layers are designed to keep you at a comfortable temperature, and the Airflow side supports aid ventilation while giving you a usable edge-to-edge sleeping surface. The 16cm encapsulated pocket springs deliver medium-firm support and minimise motion transfer, which matters if a restless partner tends to wake you. Otty includes free two-person delivery as standard, with room-of-choice delivery and old mattress removal available at checkout for an extra fee. It sits at the pricier end of boxed hybrids, but the depth, spring layer and trial terms justify the outlay for most buyers.

Who's it NOT for?
If you prefer a distinctly soft, sink-in feel, the medium-firm 6.5/10 rating may feel a little too solid, particularly for lightweight side sleepers. Equally, if you dislike any memory foam contouring and want a purely springy, traditional feel, this hybrid's foam layers may not suit you.

How firm is the Otty Pure Hybrid Bamboo and Charcoal mattress?
Otty rates it as medium-firm, 6.5/10. That means supportive enough for back and front sleepers, with sufficient give in the memory foam layers for most side sleepers, although lightweight side sleepers may find it slightly firm.
Does the Otty Pure Hybrid come with a trial and guarantee?
Yes. Buying from Otty directly, you get a 100-night trial and a 10-year guarantee, so you can try it at home across different seasons before committing.
Is the Otty Pure Hybrid good for hot sleepers?
It is designed with hot sleepers in mind. The memory foam is infused with bamboo and charcoal to help regulate temperature, and the Airflow side supports aid ventilation through the mattress.
What sizes does the Otty Pure Hybrid Bamboo and Charcoal come in?
It comes in UK Single, Small Double, Double, King, Super King and Emperor, plus EU Double and EU King. Prices range from £524 to £900 depending on size, starting from £524.99.
How is the Otty Pure Hybrid delivered?
Otty includes free premium two-person delivery as standard. Room-of-choice delivery and old mattress removal are available at checkout for an extra fee, which is handy if you cannot manage a 25cm hybrid up the stairs yourself.
