Dormeo Octasmart Premium Hybrid Mattress

The Dormeo Octasmart Premium Hybrid is a medium firm hybrid mattress that combines Dormeo's patented Octaspring foam spring technology with individually wrapped pocket springs for a level of zonal support and breathability that traditional spring mattresses simply cannot match. Aerocell and Ecocell foam layers work alongside the Octaspring system to relieve pressure and regulate temperature, while the Octavent Air System actively circulates air through the mattress to keep the sleep surface cool and fresh night after night. The result is a medium firm mattress that supports your body precisely where it needs it most, backed by an 18 year warranty and a 60 night comfort trial.

Dimensions & Weights

How it Compares

• Vs firmer models: The Octasmart Premium Hybrid sits in medium firm territory, which means it provides serious support without feeling rigid or unyielding. If you are a front or back sleeper of average to heavier build who needs reliable spinal alignment, this is likely a stronger choice than a softer option. Genuinely firm or extra firm mattresses tend to suit heavier sleepers or those with specific orthopaedic requirements who need maximum resistance.

• Vs softer models: Softer mattresses provide more immediate sink and cushioning at the shoulders and hips, which makes them a better fit for side sleepers. The Octasmart Premium Hybrid offers more structural support underneath the Aerocell layer, which keeps combination sleepers and back sleepers better aligned over the course of the night. If you regularly change position or share a bed with a partner of a different weight, the added support structure here is likely to suit you better long-term.

• Vs premium / luxury ranges: The Octasmart Premium Hybrid shares the same award-winning Octaspring technology found across the Dormeo range, along with the Octavent Air System and Sanitized protection. Where higher-end models in the wider market tend to differ is in the depth and quality of natural fillings above the spring system. This mattress prioritises breathability and responsive zonal support rather than deep natural fillings, making it an excellent value choice for sleepers who run warm or who want smart technology over traditional luxury materials.

18 Year Warranty

The Octasmart Premium Hybrid is backed by Dormeo's 18 year manufacturer's warranty against defects in materials and workmanship. For a mattress built around patented foam spring technology and multi-layer construction, this is a meaningful commitment to long-term quality, and gives you genuine peace of mind that you are investing in a mattress designed to last.
