Product Description

The Dormeo Octasmart Premium Classic is a medium-firm foam mattress powered by Dormeo's award-winning Octaspring® technology. Built in five smart body zones, it layers open-cell Aerocell foam over hundreds of 9cm Octasprings® and a supportive Ecocell® foam base, delivering 3D adaptive support, targeted pressure relief and the brand's patented Octavent™ Air System for a sleep environment that is up to three degrees cooler than traditional foam. At 17cm deep and arriving rolled and vacuum packed, it is one of the most technologically advanced foam mattresses in the Dormeo range.


Who Is This Mattress For?

A premium foam mattress best suited to sleepers who want medium-firm support, advanced temperature regulation and targeted body-zone comfort without the motion transfer of a sprung mattress.

Medium Firm Feel - 4/6: A supportive feel with added stability. Ideal for people who change sleeping position during the night and need a balance of comfort and support.

Best for

  • Back sleepers - the zoned Octaspring® core maintains the spine's natural curve and prevents the hips from sinking out of alignment
  • Front sleepers - firm enough to keep your hips level and your lower back properly supported throughout the night
  • Combination sleepers - the 5 smart body zones and 3D-adaptive Octasprings® respond as you change position, so the mattress works however you sleep
  • Hot sleepers - the Octavent™ Air System actively pushes warm air out of the mattress and draws cool air in, cooling bed temperature by up to 3°C
  • Allergy sufferers - foam construction resists dust mites and the Smart Performance cover is anti-allergenic throughout
  • Couples - Octaspring® foam absorbs movement on one side so you won't disturb each other
  • Sleepers up to 139.7kg (22st) per side

Not ideal for

  • Side sleepers who need extra cushioning for shoulders and hips and may benefit from a softer feel
  • Sleepers who prefer a very soft, sink-in feel

How it Compares

Vs softer models: The Octasmart Premium Classic's medium-firm Octaspring® core delivers noticeably more spinal support than softer options. If you spend any time sleeping on your back or front, or you change position regularly, this mattress provides the underlying structure to keep you properly aligned throughout the night. Softer mattresses may feel more immediately comfortable for side sleepers but can lack the resistance needed for sustained back or front sleeping.

Vs firm mattresses: The Aerocell foam comfort layer and zoned Octaspring® technology give the Premium Classic a cushioned feel that firm mattresses typically cannot match. It provides firm-grade support in the lumbar and hip zones while remaining gentler at the shoulders and legs - making it a smarter choice for combination sleepers who need both support and adaptability.

Vs premium memory foam ranges: Where standard memory foam can trap heat and feel slow to respond, the Octaspring® system actively ventilates as you move, making this a significantly cooler sleep. The three-layer construction - Aerocell, Octaspring® core, Ecocell® base - delivers a more differentiated support profile than most single or dual-layer foam mattresses at a comparable price.


18 Year Warranty

The Octasmart Premium Classic is backed by Dormeo's 18-year manufacturer's warranty against defects in materials and workmanship. Octaspring® technology is put through aerospace-grade quality testing, and the length of this warranty reflects the confidence Dormeo has in the long-term durability of the materials and construction.


Awards & Accreditations

Sanitized® Certified: An internationally recognised hygiene standard applied to the mattress cover and materials. Sanitized® certification confirms the mattress actively resists bacteria, dust mites and fungi - particularly important reassurance for allergy and asthma sufferers.

OEKO-TEX® Certified: An independent certification confirming that all materials used in the mattress have been tested for harmful substances and are safe for skin contact. For a mattress you sleep on every night, this is meaningful reassurance that what you're sleeping on is free from chemicals harmful to health.

Octaspring® Award-Winning Technology: Dormeo's Octaspring® system has received multiple industry awards for sleep innovation. The patented aerospace-inspired foam spring design represents a genuine technological advance in foam mattress construction, recognised across the bedding industry.

Customer Questions & Answers

  • Is this mattress suitable for a slatted base?

    Yes, this mattress is suitable for a slatted base as long as your slats are in good condition and no further apart than 7.5cm.

  • Do I need to turn this mattress?

    This is an easycare mattress, which means you do not need to turn the mattress over, however you should rotate from head to toe on a regular basis to ensure even use.

  • How long will this mattress last?

    This mattress has a warranty of 18 years.

  • What is a rolled mattress?

    A rolled mattress is a type of mattress that has been compressed and vacuum-sealed for ease of delivery and storage. This process involves removing the air from the mattress and then rolling it tightly, usually into a cylindrical shape. Rolled mattresses are typically made of foam, latex, or a combination of materials, and they can be unpacked and allowed to expand to their full size once they are delivered to their destination.

  • How long must I wait untill I can sleep on my mattress?

    Once your mattress has been unrolled we would recommend waiting 2-3 hours for the mattress to be ready to use.

  • Is this mattress suitable for a back sleeper?

    Yes, this mattress is a medium to firm tension and suitable for back sleepers.

  • Will this mattress make me hot?

    Memory foam requires your body heat to allow it to contour to your body effectively to relieve pressure. If you are a hot sleeper, we recommend using a cooling mattress protector and light-weight duvet.
