Smart Comfort at Heart

The Octasmart® Plus Mattress Topper combines three next-generation sleep technologies into one smart topper:

1. Luxurious Memory Foam

A top layer of the highest quality open-cell memory foam moulds perfectly to your unique shape for blissful comfort, adapting to, and cradling your entire body.

2. Octaspring® technology

At the heart of the topper are hundreds of 4cm Octasprings® which work together to support and cradle every inch of your body, 3-dimensionally adapting to alleviate pressure from the back, hips & shoulders.

Every single Octaspring® comfort point adapts to your body weight and releases pressure across the extra sensitive support points, improving comfort and providing better sleep quality.

3. Our Signature Ecocell™ Foam

A bottom layer of our signature Ecocell™ foam, with a 3-dimensional permanent cell structure, offers a great supportive base. As well as transforming your old mattress, the topper can be used on your guest best, sofa bed, futon or even directly on the floor.

Octavent™ Air system

The Octavent™ Air system makes your topper naturally 8 times more breathable, cooling your bed temperature by 3°C, helping you fall asleep faster, and sleep deeper for longer.

This unique system harmonises award winning Octaspring® aerospace technology with a smart performance cover, together allowing cool air to circulate inside the topper and hot air escape.

Like Sleeping on Clouds

The hundreds of comfort pockets built into the smart performance cover will make you feel like you are sleeping on tiny clouds. It brings extra freshness to the topper allowing better air circulation and letting hot air escape.

Smart Zoning

Different firmness Octaspring® springs are arranged in 3 body zones to provide customised support for your back, with more support for your hips and shoulders which allows your spine to comfortably take its natural shape.

Safe for you, Smart for the Planet

  9. Q:Can I cut my mattress topper?
    A:No. We don't recommend cutting or altering your mattress topper. Doing so will void your warranty and make the product ineligible for return.
  10. Q:Can I fold or roll my mattress topper when it's not in use?
    A:Yes. While your mattress topper can't be returned to its original vacuum-packed packaging, it can be carefully rolled or folded for convenient storage when not in use.
  11. Q:How do I keep my mattress topper in place?
    A:Dormeo mattress toppers feature an anti-slip base to help keep them securely in place. For added stability, we also recommend using a fitted sheet over both your mattress and topper.
  12. Q:Do I need to rotate my mattress topper?
    A:Yes. We recommend rotating your mattress topper from head to toe once a week for the first four weeks, then once every four weeks thereafter to help maintain comfort and performance. Mattress toppers do not need to be flipped.
  13. Q:Can I use a mattress topper on any type of mattress?
    A:Yes. Dormeo mattress toppers can be used on most mattress types, including memory foam, pocket sprung, open coil, latex and hybrid mattresses. Simply choose the same size topper as your mattress for the best fit.
  14. Q:Can a mattress topper change the feel of my mattress?
    A:Yes. A mattress topper can change the feel of your existing mattress. Depending on the topper you choose, it can add extra softness, improve pressure relief or provide additional support. If your mattress is sagging or no longer provides adequate support, replacing it may be the better long-term solution. To help you decide, visit our When to Replace a Mattress guide.
  15. Q:How long does a mattress topper take to fully expand?
    A:Please unpack your mattress topper within 30 days of delivery. Once opened, it will begin expanding immediately and regain its shape within approximately 15 minutes. Most mattress toppers are ready to use after 6–8 hours, although they may take up to 24 hours to fully expand. For the best experience, we recommend allowing the topper to reach its full depth before first use.
  16. Q:Can I use an electric blanket with my mattress topper?
    A:We do not recommend using an electric blanket with foam mattress toppers. Prolonged exposure to heat may affect the performance and shape of the foam over time and could invalidate your warranty.
  17. Q:How do I choose the right mattress topper?
    A:Choosing the right mattress topper depends on the comfort and support you're looking for. If you'd like to make a firm mattress feel softer, choose a topper designed for extra cushioning and pressure relief. If you're looking for additional support, consider a firmer topper. Mattress topper thickness can also make a difference. Thicker mattress toppers generally provide greater cushioning and pressure relief, while thinner toppers offer a more subtle comfort upgrade. Each product page includes the comfort level, key benefits and topper depth to help you choose the right option. For more advice, read our Mattress Topper Buying Guide, which explains how to choose the best topper based on your sleeping position, comfort preferences and support needs.
  18. Q:Can a mattress topper improve an old mattress?
    A:A mattress topper can improve the comfort of an older mattress by adding an extra layer of cushioning and support. However, it won't restore a mattress that is sagging, damaged or no longer provides adequate support. If your mattress has reached the end of its lifespan, replacing it may be the best long-term solution. To help you decide, visit our When to Replace a Mattress guide.
  19. Q:Which mattress topper is best for my sleeping position?
    A:Many Dormeo mattress toppers are suitable for front, back and side sleepers. Please refer to the product page for recommended sleeping positions and key comfort features to help you choose the right topper for your preferred sleeping style. For more advice, read our Mattress Topper Buying Guide, which explains how to choose the best topper based on your sleeping position, comfort preferences and support needs.
  20. Q:How do I care for my mattress topper?
    A:To help keep your mattress topper in the best condition, we recommend using a fitted sheet or mattress protector, rotating it regularly and following the care instructions supplied with your product. Most Dormeo mattress topper covers are dry clean only. Please check the care label supplied with your product for the recommended cleaning instructions. With proper care, a Dormeo mattress topper can provide many years of comfort and support. Every Dormeo mattress topper is backed by a product warranty for added peace of mind. Please refer to the product page for the applicable warranty period.
