Product Overview

Upgrade your existing mattress with the Octasmart® Essentials Cooling Mattress Topper and transform your bed into a cooler, more comfortable sleep surface without the cost of replacing it. Whether you're refreshing an older mattress, making a sofa bed more comfortable or creating a spare bed for guests, the Essentials range offers advanced cooling comfort at an affordable price.

Featuring our breathable Octacell™ technology, an advanced Cool Touch cover and your choice of Plush Comfort or Firmer Support, it's designed to help you enjoy cooler, more comfortable sleep while reducing pressure and creating a supportive sleep surface night after night.

 

Sleep Cooler, Sleep Better

Temperature plays a huge role in the quality of your sleep. Traditional foam toppers can trap heat, causing you to become too warm during the night.

The Octasmart® Essentials Cooling Mattress Topper has been designed differently.

Our advanced Cool Touch cover and breathable Octacell™ comfort layer work together to help warm air escape more efficiently, creating continuous airflow that helps maintain a cooler, more comfortable sleep environment throughout the night.

 

Two Comfy Feels. One Comfortable Price.

Everyone sleeps differently, which is why the Octasmart® Essentials Cooling Mattress Topper is available in two comfort options at exactly the same price.

Plush Comfort

The Memory Foam version gently cushions and cradles your body, providing a luxuriously soft sleeping surface that's ideal if you're looking to upgrade the comfort of an existing mattress.

Firmer Support

The Aerocell™ version provides a firmer feel, making it perfect for anyone who prefers additional support. It's also ideal for sofa beds, guest beds or even sleeping directly on the floor.

 

Firmer Support
  • Aerocell™ comfort layer
  • More supportive feel
  • Ideal for sofa beds, guest beds or those who prefer firmer support
  • Same Cool Touch cover
  • Same price
Plush Comfort
  • Memory Foam comfort layer
  • Soft, cushioning feel
  • Ideal for upgrading an existing mattress
  • Same Cool Touch cover
  • Same price

 

Next Generation Octacell™ Technology

Inspired by our award-winning Octaspring® Aerospace technology, Octacell™ represents the next generation of sleep innovation.

Its unique 3D comfort layer contains over 10,000 individual air channels*, creating continuous airflow while providing instant ergonomic pressure relief and responsive support.

Unlike traditional foam, Octacell™ is designed to breathe naturally, helping you sleep cooler while enhancing overall comfort.

Cool Touch Cover

Our signature Cool Touch cover is woven with innovative cooling fibres and features hundreds of micro air comfort pockets to deliver a noticeably cooler feel from the moment you lie down, helping you enjoy a fresher, more comfortable night's sleep.

Octacell™ Comfort Layer

Available in either Memory Foam or Aerocell™, the Octacell™ comfort layer provides pressure-relieving comfort while promoting continuous airflow to help maintain a cooler, more comfortable sleep environment. Simply choose the feel that's right for you.

Ecocell® Support Base

Breathable Mesh Sides

Highly breathable mesh side panels encourage warm air to escape while allowing fresh air to circulate throughout the night, helping you stay cooler and more comfortable while you sleep.

 

Safe for You. Better for the Planet.

Our innovative Octacell™ technology uses 25% less material than traditional foam production while creating no manufacturing waste. Using less material also helps reduce CO₂ emissions as part of our commitment to creating more sustainable sleep products.

Every material is carefully selected to be safe for your home, your family and your wellbeing.

  7. Q:Can I take my Dormeo product abroad?
    A:Yes, you can take your Dormeo product abroad for personal use. Please note that any transportation costs, import duties or customs charges are your responsibility. Your warranty remains valid in line with our warranty terms and conditions.

  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.
