The Hypnos Majesty Ortho Sublime is 30cm deep and filled with natural materials: RWS certified British wool, sustainably sourced cotton and recycled Solotex and eOlus fibres, all wrapped in a breathable Belgian damask cover. It arrives flat rather than rolled and boxed, which suits the natural fillings. It comes in nine sizes, including Emperor and EU options. It's a serious spend, but the natural fillings and 10-year manufacturer guarantee help justify it. If you want firm support without synthetic foams, it deserves a close look.

Why should you choose this mattress?
This mattress is a good fit if you prefer a firm feel and care about what's inside your bed. The fillings are natural and traceable: British wool certified to the Responsible Wool Standard, plus cotton that wicks moisture away, which means it should sleep cooler than foam-heavy alternatives. If you're a hot sleeper, that breathability is a genuine advantage. The ReActive 8-turn pocket springs are designed to respond quickly as you move, so you get support that adjusts through the night rather than a rigid platform. Hypnos backs it with a 10-year guarantee, and the choice of nine sizes, from UK Single up to Emperor and EU sizes, means awkward bed frames are less of a problem than usual.
Key features & layer details
Cover
An unbleached, chemical-free cotton cover in Belgian damask, which means a soft, breathable sleeping surface without harsh treatments. Damask is a tightly woven fabric that wears well over time.
Comfort fillings: British wool
Insulating British wool cushions the whole body, which means gentle pressure relief rather than the sink-in feel of memory foam. Wool also helps keep the surface temperate.
Comfort fillings: cotton
Cotton wicks away excess moisture and works alongside the wool to regulate temperature. In practice, that means a drier, more comfortable feel in both summer and winter.
Comfort fillings: Solotex and eOlus fibres
Recycled Solotex and eOlus fibres add to the cushioning while promoting airflow. That extra breathability matters most if you tend to overheat at night.
Support system: ReActive pocket springs
A core of ReActive 8-turn pocket springs supports key areas of the body. Each turn lets the spring react faster to your movements, which means the mattress adjusts as you change position rather than lagging behind.

Best suited for?
Warm sleepers
Wool and moisture-wicking cotton work with airflow-boosting recycled fibres, which means the surface should sleep cooler than foam-heavy alternatives for anyone who overheats at night.
Eco-conscious buyers
Fillings include RWS certified British wool, sustainably sourced cotton and recycled Solotex and eOlus fibres, so you know what is inside your bed and where it came from.
Back sleepers
A firm feel and a core of ReActive 8-turn pocket springs give steady support that responds as you move, rather than a rigid platform.
Combination sleepers
Each turn in the ReActive pocket springs lets them react faster to your movements, which means the mattress adjusts as you change position instead of lagging behind.
European bed frames
Nine sizes, including Emperor and EU options, mean awkward or non-standard frames are less of a problem than usual when choosing this mattress.
This is a firm mattress, so lightweight side sleepers may find it doesn't yield enough at the shoulder and hip. If you love the cocooning hug of memory foam, the springy, natural feel here will disappoint. And with a premium starting price, budget shoppers will find better value elsewhere, though rarely with fillings this good.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
Is the Hypnos Majesty Ortho Sublime firm or soft?
It's a firm mattress. The wool and cotton fillings add gentle surface cushioning, but the underlying feel is supportive rather than plush. It suits back and front sleepers who like a firmer base, although lightweight side sleepers may find it a little too unyielding.
Does the Hypnos Majesty Ortho Sublime come rolled in a box?
No, it's delivered flat rather than rolled and boxed, which protects the natural wool and cotton fillings. MattressNextDay lists free next-day delivery, though that's a retailer offer rather than a Hypnos guarantee, and it also offers old mattress removal as a paid add-on.
What guarantee does the Hypnos Majesty Ortho Sublime have?
It comes with a 10-year Hypnos manufacturer guarantee. Note that no trial period is mentioned on the retailer listing, so check return terms with your chosen retailer before ordering if you'd want the option to send it back.
What sizes does the Hypnos Majesty Ortho Sublime come in?
Nine sizes in total: UK Single, Small Double, Double, King, Super King and Emperor, plus EU Single, Double and King.
What is the Hypnos Majesty Ortho Sublime made of?
It's 30cm deep, made in the UK, with RWS certified British wool, sustainably sourced cotton and recycled Solotex and eOlus fibres over a core of ReActive 8-turn pocket springs. The cover is unbleached, chemical-free cotton in Belgian damask, and it meets the BS7177 fire safety standard for domestic use.
