Dual Technology — Twin System HS Springs + Myform Memory Air HD
The Tresor’s structural core uses Dorelan’s Dual Technology — the same advanced hybrid system found in the Stylus, taken to its fullest expression at the Signature Collection level.
Twin System HS pocket springs use carbon-steel concentric double-coil construction: the outer coil provides initial soft comfort; the inner coil engages under greater body pressure to deliver deep, progressive structural support. Distributed across 7 differentiated support zones, the springs calibrate their response precisely to the body’s key areas — lighter at shoulders, firmer at the lumbar region, progressive through hips and legs. The carbon-steel specification ensures superior elasticity and long-term shape retention beyond what standard steel springs can maintain.
Above the spring core, a layer of Myform Memory Air HD provides the comfort interface — Dorelan’s highest-density open-cell memory foam with an extremely fine molecule structure. It adapts precisely to body shape and weight, relieving pressure points with gradual, body-temperature-responsive contouring, while its open-cell architecture maintains exceptional breathability and prevents heat accumulation within the foam layer.
Comfort Suite Cover — The Art of Noble Materials
What elevates the Tresor above the Stylus is the Comfort Suite cover — Dorelan’s most prestigious cover system, featuring a refined blend of noble fibres and technical materials that defines the Signature Collection.
The Comfort Suite padding combines silk, Memory Clima thermoregulating material, and further layers of premium natural fibres — creating a surface of extraordinary softness, thermal intelligence, and sensory refinement. Silk’s bidirectional temperature-balancing properties work in harmony with Memory Clima’s active thermoregulation to maintain the ideal sleeping microclimate in every season. The capitonné quilting — hand-stitched with Dorelan’s master craftsmen — adds a visual and tactile depth that reflects the Tresor’s position as a luxury sleep object.
Removable Cover, Fibersan and Hygiene Certification
The Tresor’s cover removes via zip fastening for practical washing — maintaining the high hygiene standards that Dorelan’s certifications demand. The cover receives Fibersan treatment — natural anti-mite and anti-allergen protection using essential oils of lavender, eucalyptus, and lemon.
The Tresor carries EU medical device certification under Regulation 2017/745 (MDR) and is produced under Dorelan’s hygiene certification — the first Italian bedding company to achieve this standard across the full manufacturing process from raw material sourcing to delivery.

FAQ:
Q: What distinguishes the Tresor from the Stylus — both use Dual Technology, so what is the difference?
Both the Tresor and the Stylus use Dual Technology with Twin System HS springs and Myform Memory Air HD — and at the spring and foam level, the engineering is consistent. The meaningful difference lies in the cover and surface materials, the construction depth, and the overall positioning within the Dorelan range.
The Stylus uses a viscose and polyester microfibre cover with silk and organic cotton padding — excellent quality, but focused on freshness and breathability. The Tresor uses Dorelan’s full Comfort Suite cover — their most prestigious cover system, featuring silk alongside Memory Clima thermoregulating material and capitonné quilting hand-stitched by master craftsmen. This represents a step change in surface luxury, thermal intelligence, and sensory refinement.
The Tresor also stands at 31cm in height — significantly deeper than the Stylus — reflecting the additional layering of premium materials in the Comfort Suite system. For a buyer for whom the surface feel, thermal precision, and aesthetic refinement of the mattress matter as much as the engineering beneath, the Tresor delivers at a level the Stylus does not attempt to reach.

Q: What is Memory Clima and what does it add to the Comfort Suite cover?
Memory Clima is Dorelan’s thermoregulating material designed to be integrated into the surface layers of a mattress — and in the Tresor’s Comfort Suite cover, it works in active partnership with the silk padding to manage sleeping temperature with precision.
Memory Clima uses nanotechnology to continuously regulate the contact temperature between the body and the mattress surface. Rather than simply absorbing heat or allowing it to dissipate passively, it manages the temperature exchange actively — maintaining the surface at a temperature close to the ambient sleeping environment rather than warming progressively as the night continues.
Combined with silk’s natural bidirectional thermal properties — cool in summer, warm in winter — the Comfort Suite creates a surface that responds intelligently to both seasonal temperature variation and individual body heat generation throughout the night. For warm sleepers, this combination is particularly valuable: the surface remains fresh even during periods of high body heat without requiring the sleeper to reposition or uncover.
Q: What is capitonné quilting and why does it matter on a premium mattress?
Capitonné is a traditional European upholstery quilting technique — and on the Tresor, it is more than an aesthetic choice.
In capitonné quilting, the cover material is stitched through multiple layers in a regular pattern that creates characteristic indentations — in the Tresor’s case, visible as the refined square pattern across the cover surface. This technique, applied by Dorelan’s master craftsmen, serves functional purposes: it keeps the padding layers evenly distributed and prevents shifting or bunching over time, maintains the Comfort Suite’s loft and softness consistently across the entire surface, and adds structural integrity to the cover that flat-quilted covers do not provide.
At the Signature Collection level, hand-applied capitonné quilting also signals craftsmanship investment — each mattress receives individual attention from skilled artisans in Dorelan’s Italian manufactory, rather than being assembled by automated processes.

Q: How do I care for the Dorelan Tresor and how long should it last?
The Tresor is designed for longevity — the combination of carbon-steel springs, high-density Myform Memory Air HD, and Dorelan’s hygiene-certified manufacturing means it is built to maintain consistent performance over many years of nightly use.
The Comfort Suite cover removes fully via zip fastening and can be machine washed — follow the care label temperature guidance carefully, as the silk and Memory Clima materials require a gentle wash cycle. Air dry the cover where possible rather than tumble drying on high heat. Always ensure the cover is completely dry before replacing.
Rotate the mattress regularly — every 3 to 6 months — to distribute wear evenly across the surface and spring system. Use a high-quality mattress protector beneath the cover to protect the Comfort Suite from moisture and skin oils between washes, significantly extending the cover’s condition over time.
The Fibersan anti-mite treatment on the cover provides ongoing hygiene protection between washes. The 5-year guarantee covers the core, spring system, and construction — for a mattress at this quality level, with proper care, significantly longer performance is typically achieved.
Q: The Dorelan Tresor is one of the most expensive mattresses available at Sleep Gallery — what precisely justifies this price?
The Tresor’s price reflects a layering of investments — in engineering, materials, and craft — that together produce a sleeping experience that no lower-priced mattress can honestly replicate.
The Dual Technology foundation with carbon-steel Twin System HS springs and Myform Memory Air HD delivers a precisely calibrated, progressive support system across 7 zones — the same engineering level as the Stylus, already at a premium specification.
The Comfort Suite cover elevates the Tresor to a different category entirely. Silk and Memory Clima as primary surface materials represent a significant cost premium over synthetic or standard natural alternatives — but deliver thermal intelligence and sensory luxury that cannot be achieved with less refined materials. The capitonné quilting, applied by master craftsmen, adds artisanal labour investment that automated manufacturing cannot substitute.
At 31cm in height, the Tresor contains more layered material at higher specification than any other Dorelan mattress — each centimetre reflects a considered material choice rather than filling. EU medical device certification, Dorelan’s hygiene certification as Italy’s first certified bedding manufacturer, and 55+ years of Italian mattress craftsmanship complete a quality assurance framework that independently verifies what the price claims.
For those who view their mattress as a long-term investment in daily wellbeing rather than a commodity replacement, the Tresor represents the most comprehensive expression of what Italian sleep engineering can achieve.
