The Hypnos Organics 6 layers natural latex over ReActivePro pocket springs, wrapped in British lambswool, peace silk, organic wool and cotton, with hemp and flax for moisture control. At 31cm deep and double-sided, it's built to be flipped, which means it should wear more evenly over the years. It sits firmly in luxury territory. If you want firm support with fully natural fillings, and no harmful FR chemicals or pesticides in the build, it makes a strong case. Lighter sleepers who prefer a softer feel should look elsewhere.

Why should you choose this mattress?
Everything in this mattress is natural, and the Soil Association certification means the organic claims are independently verified rather than just marketing. The natural latex layer relieves pressure without synthetic foams, while the hemp, flax and cotton blend wicks moisture away, which means a drier, cooler night if you tend to overheat. It's double-sided, so flipping it regularly should extend its useful life, a genuine point in its favour at a premium starting price. Feather & Black states a 10-year guarantee and free delivery, though it's sensible to confirm whether those are manufacturer or retailer terms before you buy. The price is steep, but the materials and craftsmanship go some way to justifying it.
Key features & layer details
Sleep surface
An organic wool and cotton sleep surface that's naturally breathable. This is the layer you'll feel first, soft and temperature-regulating against your skin.
Natural latex layer
Natural latex relieves pressure at your hips and shoulders, which means less tossing and turning. It does this without any synthetic foam.
Moisture-wicking layer
A natural blanket of cotton, hemp and flax draws moisture away from you as you sleep. Helpful if you run warm at night.
Pocket springs
Hypnos' ReActivePro 10-turn pocket springs respond individually to the shape of your body, encouraging natural spinal alignment. Each spring moves on its own, so your partner's movement is less likely to disturb you.
Wool and silk blend
Layer upon layer of British lambswool blended with ethically farmed peace silk. These natural fillings add cushioning and help regulate temperature through the seasons.

Best suited for?
Eco-conscious buyers
Natural latex, British lambswool, organic wool and cotton make up the build, and Soil Association certification means the organic claims are independently verified.
Warm sleepers
A cotton, hemp and flax layer draws moisture away as you sleep, which means a drier, cooler night if you tend to overheat.
Couples
Each ReActivePro pocket spring moves on its own, so your partner's movement is less likely to disturb you during the night.
Back sleepers
Firm support from the pocket springs, topped with a natural latex layer, encourages natural spinal alignment while easing pressure at the hips and shoulders.
Heavier sleepers
The firm feel and individually responding 10-turn pocket springs give solid support, while the 31cm depth and five layers add cushioning and durability.
This is a firm mattress, so lightweight side sleepers may find it too unyielding at the shoulder and hip. It's also a serious investment, and it's double-sided, so you'll need to be able to flip a substantial 31cm mattress regularly to get the best from it.
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 Organics 6 mattress firm or soft?
It's described as firm. That suits back and front sleepers, and heavier builds generally, although lighter side sleepers may find it a little too solid for comfortable pressure relief at the shoulder.
Is the Hypnos Organics 6 really organic?
Yes, it's Soil Association certified organic, so the claim is independently verified. It's also stated to be free from harmful FR chemicals, pesticides and genetic modifications, with natural fillings including organic wool, organic cotton, hemp, flax and natural latex.
Does the Hypnos Organics 6 need to be flipped?
The Feather & Black listing describes it as double-sided and suitable for flipping. Regular flipping helps the fillings settle evenly, which should extend the mattress's life, though at 31cm deep it's a two-person job.
What guarantee comes with the Hypnos Organics 6?
Feather & Black states a 10-year guarantee along with free delivery. These terms appear on the retailer's page, so it's worth confirming with them whether they're manufacturer or retailer-specific before ordering.
What sizes does the Hypnos Organics 6 come in?
It's available in UK Single, Double, King and Super King.
