Why our sleep experts loved it
The Hypnos Inspired by Nature 05 gave me that familiar premium-mattress dilemma in the Bensons showroom. The quality is obvious. The price is also obvious. I support much of what Hypnos is doing here, especially the British wool, the traceable sourcing and the proper hand finishing, but over £3,000 for a double pushes the argument into uncomfortable territory.
This is a 31cm deep, turnable mattress with a serious natural-fill specification. It uses five fleeces of RWS certified British wool from the Woolkeepers Community, a 50mm graphite-infused 100% natural latex layer, and a natural fruit fibre layer made from banana, pineapple and orange fibres blended with cotton. That is far beyond the usual sprinkle of wool over foam. The difficulty is simple: excellent ingredients still need to earn a very high ticket price.
Build and specification
The showroom sample looked properly made. The Hypnos damask cover felt cool and crisp to the hand, with viscose derived from wood pulp and a 100% natural, chemical-free fire retardancy treatment. The British wool tufting was tidy, the borders were firm, and the mattress had the dense, traditional feel I expect from Hypnos rather than the puffed-up softness common on cheaper display beds.
Support comes from ReActivePro 10-turn pocket springs. Under body weight, the response felt controlled and quite precise, especially through the hip area. Edge support was stronger than most boxed hybrids I test: Triple Edge Protection combines 3 rows of firmer edge springs on both sides, a metal frame and side stitching. The 4 rows of true hand side-stitching help the perimeter feel braced rather than decorative. Compared with the Simba Hybrid Pro, this feels more traditional and more substantial at the edge, although Simba wins for ease of delivery and a less frightening outlay.
Hypnos also leans hard into the environmental story. RWS wool, Woolkeepers traceability, Eden Project endorsement, and recyclable packaging made from sugar cane and recycled plastic are all credible points. I do not dismiss them. I also do not think they magically settle the price question. A sustainable mattress can still be overpriced for many households.
Feel and comfort in store
I tested the medium comfort choice. It felt at its best on my side, where the wool and 50mm latex gave a buoyant cushion under the shoulder. The surface has lift rather than that slow memory-foam bog, so changing position was easy. Nice feel. Expensive feel, too.
Back sleeping was less persuasive. The spring unit kept me supported, and average-weight sleepers who like a cushioned top should get on with it. A flatter, firmer posture would probably come from the firm option. At this price, I would not buy the medium for back sleeping without testing both tensions side by side.
The breathable claims are more believable than most. Wool, cotton, latex and fruit fibres should manage moisture better than dense synthetic foams, and the shop-floor feel was dry and airy. A showroom cannot tell me how it behaves during a hot July night, so I would still treat the cooling language with caution.
Best matches for this mattress
Side sleepers of average build are the safest audience for the medium version. The shoulder relief is the strongest part of the feel, and the support below does not vanish once weight goes through the comfort layers. Lighter side sleepers may enjoy it quickly because the surface responds without needing much force.
Back sleepers should be more careful. The medium has enough structure for many people, but anyone chasing a firmer, flatter feel should move straight to the firm model during testing. Heavier sleepers also need that comparison, since the plush upper layers may compress more deeply over time. Couples will like the usable edge width, but partner movement needs a home trial to judge properly.
Customer feedback picture
No verified customer reviews for this exact model were supplied with the product information, so I cannot quote owner experiences or pretend there is a settled buyer consensus. For a mattress costing over £3,000 in a double, that absence is annoying rather than trivial.
The missing evidence would matter most around long-term use. I would want owners to report on settlement in the wool and latex, edge firmness after regular sitting, and whether the fruit fibre and wool layers really stay comfortable through summer. The free 10-year guarantee is welcome, but it is not the same as knowing how the mattress feels in year five.
Limits of this showroom test
I tested it in store, not through a home sleep trial.
I could not check long-term settlement of the wool, latex and fruit fibre layers.
I could not measure real overnight heat regulation.
I could not properly assess delivery, turning at home or partner disturbance.
Verdict after handling it
The Hypnos Inspired by Nature 05 is a high-quality mattress with a strong specification: five fleeces of RWS certified British wool, 50mm natural latex, natural fruit fibre, ReActivePro 10-turn springs, Triple Edge Protection, 8 flag-stitched handles on larger sizes and a 10-year guarantee. The 90cm size has 4 handles. It is made in Buckinghamshire by Royal Warrant holders Hypnos, exclusively for Bensons for Beds.
I get the appeal. I just do not like the price. The medium model felt comfortable, breathable and especially well suited to side sleeping, yet over £3,000 for a double is a serious ask. I would compare it with the firm version, then try a Vispring or Harrison Spinks natural-fill alternative before signing off that spend.
