The Octaspring 8500 is Dormeo's deepest and most luxurious Octaspring mattress, built around three layers of individually zoned Octaspring foam springs and topped with a deep memory foam comfort layer. The three-layer Octaspring construction delivers 8-zone body support, actively ventilates the sleep surface, and reduces motion transfer - making it a particularly strong choice for side sleepers and couples. At 30cm deep, this is a premium, substantial mattress that sits at the top of the Octaspring range.
A foam mattress best suited to sleepers who want soft medium support, outstanding breathability through Dormeo's three-layer Octaspring system, and deep memory foam pressure relief across 8 zoned support zones.
Soft Medium Feel - 2/6: A gentle balance of softness and support. Soft Medium is perfect for side sleepers and combination sleepers who want pressure relief with a little more stability and support.

Octaspring Foam Springs (3 Layers)
What it is: Dormeo's unique octagonal foam springs that provide excellent support and comfort alongside outstanding ventilation. This mattress features three layers of Octaspring foam springs, each independently zoned to provide different levels of support across the body.
How it helps you sleep: Helps distribute weight evenly and align the spine across 8 distinct body zones, enabling you to fall asleep quicker and spend more time in a deeper, more restorative sleep.
Memory Foam
What it is: An innovative pressure-sensitive foam that shapes to the contours of the body and springs back when pressure is released.
How it helps you sleep: Enhances circulation, equalises pressure to relieve back problems, promotes better spinal alignment, and reduces allergens for a fresher, healthier night's sleep.
360 Degree Comfort - 8-Zone Body Support
What it is: Dormeo's Octaspring technology where hundreds of individual foam springs move three-dimensionally to cradle the body, here arranged across eight distinct support zones from head to toe across three separate spring layers.
How it helps you sleep: Each spring conforms to your body's contours in all sleeping positions, reducing pressure points and promoting healthy blood flow for a deeply comfortable, undisturbed sleep.
No Transfer of Movement
What it is: A mattress feature delivered by the independent Octaspring foam springs and the deep memory foam layer, which absorb and isolate movement on one side of the bed.
How it helps you sleep: Means you will not be disturbed when your partner gets up or moves during the night, helping you enjoy a more peaceful and uninterrupted sleep.
Superstretch Cover
What it is: A highly flexible cover that offers significantly more stretch than standard covers, upholstered in a stretch knit fabric made from 99% polyester and 1% elastane.
How it helps you sleep: Provides additional flexibility to fully support the mattress core, allowing you to move freely throughout the night for maximum comfort.
Built-in Handles
What it is: Discreet handles integrated into the sides of the mattress that can be hidden when not in use.
How it helps you sleep: Makes repositioning and rotating the mattress easy, ensuring it stays correctly placed for consistent, undisturbed sleep.

Vs softer mattresses: The Octaspring 8500 sits at a soft medium tension rather than a purely soft feel, which means it offers more support beneath the memory foam comfort layer than a soft-only mattress. Side sleepers who find very soft mattresses feel unsupported over time, or those who change position during the night, will appreciate the additional stability the three-layer Octaspring system provides underneath.
Vs medium mattresses: If you are a side sleeper or share a bed, the Octaspring 8500 is likely the better choice over a standard medium mattress. The soft medium tension gives noticeably more cushioning at the shoulders and hips, and the three independent Octaspring layers do more to reduce partner disturbance than a conventional medium foam or spring mattress.
Vs the Octasmart Premium range: The Octaspring 8500 sits in the original Octaspring collection, which is a more established, foam-focused range. The key difference is construction depth and the number of Octaspring layers: the 8500 has three separate layers of Octaspring foam springs reaching 30cm deep, compared to a single layer in the Octasmart Premium models at 17cm or 22cm. This makes the 8500 a more enveloping, deeply cushioned mattress, better suited to those who prioritise pressure relief and a plush feel over a more versatile, hybrid-style construction.
The Octaspring 8500 is backed by Dormeo's 20-year manufacturer's warranty against defects in materials and workmanship. As Dormeo's flagship Octaspring mattress, the 8500 is built to last - and the extended warranty reflects the quality and durability of the three-layer Octaspring construction.
Dormeo Octaspring Technology is an internationally recognised, award-winning foam spring system exclusive to Dormeo. The Octaspring has received recognition across the sleep and innovation industries for its unique combination of foam spring support, zoned spinal alignment, and active temperature regulation - validated by independent testing and consumer awards. The 8500 represents the pinnacle of the Octaspring range, featuring three layers of the technology for the deepest and most comprehensive version of the system available.
The Octaspring 8500 is Dormeo's most complete expression of Octaspring technology - three layers deep, 8 zones of body support, and a substantial 30cm profile that puts it firmly in premium mattress territory. If you are a side sleeper, share a bed, run warm at night, or simply want the most cushioned and breathable version of what Dormeo does best, this is the mattress to consider.
