Product Description

The Octasmart Premium Plus is a medium-feel foam mattress from Dormeo's Premium Collection, built around their award-winning Octaspring foam spring system and a generous memory foam comfort layer. Engineered to distribute weight evenly and align the spine, it combines ecocell foam and 5-zone Octaspring technology with the Octavent Air System to keep the sleep surface fresher and cooler throughout the night. The result is a versatile, anti-allergenic mattress that suits a wide range of sleeper types and is designed with sustainability at its core.


Who Is This Mattress For?

A foam mattress best suited to sleepers who want medium support, effective temperature regulation through Dormeo's Octavent Air System, and zoned spinal alignment across five distinct body zones.

Medium Feel - 3/6: The goldilocks option - not too firm, not too soft. Medium is the most versatile firmness level, balancing comfort and support in a way that suits most sleeper types.

Best for

  • Side sleepers - the memory foam comfort layer cushions shoulders and hips to relieve pressure points while keeping your spine aligned
  • Back sleepers - supportive enough to maintain the spine's natural curve without feeling too firm
  • Front sleepers - firm enough to stop your hips sinking, comfortable enough that you will not notice
  • Hot sleepers - the Octavent Air System has been proven to be 8x more breathable than traditional memory foam, cooling the sleep surface by up to 3°C
  • Allergy sufferers - the anti-allergenic, sterilised foam and Smart Performance Cover create a genuinely dust-mite resistant sleep environment
  • Sleepers up to 139kg (22st) per side

Not ideal for

  • Sleepers who prefer a very soft, plush sink-in feel
  • Sleepers who prefer a firm or extra firm mattress

Inside This Mattress

Octaspring Foam Springs
What it is: Dormeo's unique octagonal foam springs that provide excellent support and comfort alongside outstanding ventilation. Each spring moves independently within the mattress structure.
How it helps you sleep: Helps distribute weight evenly and align the spine, 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.

Ecocell Foam
What it is: Dormeo's unique permanently elastic foam with a 3D cellular structure that provides efficient air circulation and adaptive support.
How it helps you sleep: Reduces painful pressure points that can cause tossing and turning, while the breathable structure helps maintain a comfortable sleeping temperature all night.

Octavent Air System
What it is: Dormeo's unique ventilation system proven to be 8x more breathable than traditional memory foam, with a constant airflow that can cool bed temperature by up to 3 degrees Celsius.
How it helps you sleep: Your body movements push warm, humid air out of the specially designed sides of the mattress while drawing fresh air in, creating a fresh, healthy sleeping surface night after night.

360 Degree Comfort - 5-Zone Body Support
What it is: Dormeo's Octaspring technology where hundreds of individual foam springs move three-dimensionally to cradle the body, arranged in five distinct support zones from head to toe.
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.

Smart Performance Cover
What it is: Dormeo's anti-allergenic cover featuring hundreds of built-in comfort pockets for extra freshness and circulation.
How it helps you sleep: Provides additional breathability and a hygienic sleep environment, helping to keep allergens at bay for a cleaner, more comfortable night's sleep.

Eco Friendly Construction
What it is: A design philosophy indicating the mattress has a significantly reduced environmental impact - Dormeo's Octasmart Premium range is manufactured with 50% fewer carbon emissions.
How it helps you sleep: Provides a healthier sleep environment while contributing to a sustainable future, giving you peace of mind alongside a comfortable night's sleep.

How it Compares

Vs firmer mattresses: The Octasmart Premium Plus sits at a genuine medium tension, meaning it offers noticeably more cushioning through the memory foam and Octaspring layers than firmer alternatives. If you sleep on your side or find firmer mattresses aggravate pressure points at the hips or shoulders, this is the more comfortable choice. Firmer models will suit heavier sleepers or those who prefer a more rigid, less contouring surface.

Vs softer mattresses: The Octasmart Premium Plus provides considerably more structural support than a soft or soft-medium mattress. Softer mattresses can feel more immediately luxurious but may allow the hips to sink too far, particularly for back and front sleepers, which can compromise spinal alignment over time. The medium tension here keeps the body in a more neutral, supported position throughout the night.

Vs the Octasmart Premium Hybrid Plus: The key difference between these two mattresses is construction. The Hybrid Plus adds a layer of traditional pocket springs beneath the Octaspring system, which gives it slightly more responsive, spring-like support and a 22cm profile versus 17cm here. If you prefer a more traditional spring feel or sleep with a partner and want the additional motion isolation of pocket springs, the Hybrid Plus is worth considering. The Premium Plus is the leaner, more accessible option in the range with the same Octaspring technology at its core.


18 Year Warranty

The Octasmart Premium Plus is backed by Dormeo's 18-year manufacturer's warranty against defects in materials and workmanship. For a mattress at this price point, that level of manufacturer confidence is worth noting - it reflects the durability and long-term performance built into Dormeo's Octaspring technology.


Awards & Accreditations

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 - offering a genuinely different approach to mattress construction that has been validated by independent testing and consumer awards.


Ready to Upgrade Your Sleep for Better Rest?

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 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.
