Product Overview

The Octaspring® 6500 Memory Foam Mattress is the more supportive choice within our Luxury Octaspring® range, combining a balanced medium-firm feel with premium cushioning and breathable comfort.

At 23cm deep, it combines a 4cm memory foam comfort layer with two layers of Octaspring® foam springs. The memory foam gently moulds to your body to cushion pressure points, while the Octaspring® layers provide responsive support and help distribute your body weight across the mattress.

Within the upper Octaspring® layer, different firmnesses are arranged into three comfort zones, providing softer cushioning around the head, shoulders and legs with firmer support around the hips.

The result is a balanced combination of pressure-relieving comfort, targeted support and enhanced breathability — ideal if you prefer a more supportive sleep feel with less sink.

Targeted support where your body needs it

Comfort isn’t just about how soft or firm a mattress feels. It’s also about how well it supports different areas of your body.

The Octaspring® 6500 uses zoned foam springs of different firmnesses to deliver targeted comfort and support. Softer zones cushion the head, shoulders and legs, while firmer support around the hips helps create a more balanced sleep surface.

Each Octaspring® foam spring responds independently, adapting as you move and helping to distribute your body weight across the mattress.

Pressure-relieving memory foam comfort

Above the Octaspring® support system sits a 4cm memory foam comfort layer.

Memory foam gently moulds to the shape of your body, helping cushion key pressure points while the Octaspring® layers underneath provide responsive support.

Together, the layers give the 6500 its distinctive medium-firm feel — cushioned at the surface with reassuring support underneath.

8x more breathable than traditional memory foam

Traditional blocks of memory foam can restrict airflow through a mattress. Octaspring® foam springs are designed with an open structure that allows air to move more freely.

The Octaspring® ventilation system has been shown to be 8x more breathable than traditional memory foam, helping warm air escape and fresh air circulate through the mattress.

That enhanced airflow helps create a fresher, more comfortable sleep environment throughout the night.

Removable Superstretch® cover

The Octaspring® 6500 is finished with a Superstretch® cover, made from fabric designed to stretch up to 50% more in each direction than traditional fabric, helping you experience the comfort and responsiveness of the layers beneath.

The top section of the cover is removable and washable, making it easier to keep your sleep surface feeling fresh.

Built-in handles are discreetly positioned around the mattress to make moving or rotating it easier.

The cover also features Ecofresh protection, using probiotic ingredients designed to help protect the mattress from allergens, dust mites and bacteria.

The Octaspring® difference

Unlike traditional foam blocks, Octaspring® technology uses individual honeycomb-shaped foam springs that move independently and respond to your body.

Their open construction combines the contouring comfort of foam with enhanced airflow, while different firmnesses can be arranged into targeted zones to provide comfort and support across different areas of the body.

It’s this combination of responsive support, pressure-relieving comfort and breathability that gives Octaspring® its distinctive feel.

  5. Q:What is the Dormeo 200 Night Trial?
    A:Selected Dormeo mattresses and mattress toppers come with our 200 Night Trial, giving you up to 200 nights to experience your new product in the comfort of your own home. If you're not completely satisfied, you can return it for a refund or exchange it for another eligible model within 200 nights of delivery (one exchange or return per order). To qualify, your product must be opened within 30 days of delivery and used with a mattress protector. Please note that the 200 Night Trial does not apply to all products, so we recommend checking the product page for eligibility. Full terms and conditions apply, for full detsails please see our 200 Night Trial page.
  6. Q:How do I return my product?
    A:If you wish to return your order, please contact our Customer Care team, who will guide you through the returns process. Return eligibility depends on the product you've purchased. Selected mattresses and mattress toppers are covered by our 200 Night Trial, while other products are covered by our standard returns policy. Full details can be found on our Returns page.
  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. However, if you need to make a warranty claim, you'll be responsible for any costs associated with returning the product, and claims can only be processed from a valid UK delivery address.
  8. Q:How can I contact Dormeo?
    A:If you have any questions before or after your purchase, our Customer Care team is here to help. Visit our Contact Us page to find our latest contact details, opening hours and available support options, including phone and email.
  9. Q:Do I need to flip my mattress?
    A:No. Dormeo mattresses are designed to be rotated rather than flipped. We recommend rotating your mattress from head to toe once a week for the first four weeks, then once every four weeks thereafter to help maintain comfort and support.
  10. Q:Can I use my mattress on a slatted bed base?
    A:Yes. Dormeo mattresses are suitable for use on standard bed frames and slatted bed bases. To ensure proper support and maintain your warranty, the gaps between slats should be no wider than 7.5cm (3 inches). Wider gaps may reduce the mattress's performance and could invalidate your warranty.
  11. Q:Which mattress is best for back pain?
    A:Choosing the right mattress for back pain depends on your individual needs, preferred sleeping position and comfort preference. Our Best Mattress for Back Pain Guide can help you find the right option. If you'd like personalised advice, our Sleep Experts are always happy to help.
  12. Q:How can I help prevent mould on my mattress?
    A:To help prevent moisture build-up, we recommend airing your mattress regularly by removing the bedding and allowing fresh air to circulate. Ensure your bedroom is well ventilated and avoid placing your mattress directly against a wall where moisture can become trapped. Damage caused by mould is not covered under warranty.
  13. Q:Do you sell children's mattresses?
    A:Yes. While we don't have a dedicated children's mattress range, many of our mattresses are suitable for children and teenagers. Simply choose the right size and comfort level for your child's needs, with our single and small double mattresses being popular choices.
  14. Q:Does a new mattress have a smell?
    A:As with many new foam mattresses, you may notice a slight odour when your mattress is first unpacked. This is completely normal, harmless and should fade within 24–48 hours. Simply allow the mattress to air in a well-ventilated room before use. If the odour persists, please contact our Customer Care team.
  15. Q:Can you take away my old mattress?
    A:Yes! We offer a Mattress Recycling Service, so we can take away your old mattress when your new one is delivered. Simply add Mattress Recycling to your order and our delivery team will collect your old mattress at the same time as delivering your new one. Your old mattress will then be taken away for responsible recycling, helping to keep it out of landfill. Our Mattress Recycling Service is available to most UK addresses. Once you enter your delivery address at checkout, you'll be able to see whether the service is available in your area. Unfortunately, we're unable to offer mattress recycling in Gibraltar, the Channel Islands or the Isle of Man.
  16. Q:How long does my mattress take to fully expand?
    A:Please unpack your mattress within 30 days of delivery. Once opened, it will begin expanding immediately and regain its shape within approximately 15 minutes. Most rolled mattresses are ready to sleep on after 6–8 hours, although they may take up to 24 hours to reach their full depth and optimum performance. For the best sleeping experience, we recommend allowing the mattress to fully expand before first use where possible.
  17. Q:Can I try a Dormeo mattress before I buy?
    A:Yes. You're welcome to visit our Dormeo showroom to see and try selected mattresses before you buy (subject to stock availability). Our showroom is located at: Dormeo Showroom Wye House Wye Industrial Estate 376 London Road High Wycombe HP11 1LH Opening Hours: Monday – Saturday: 9:00am – 5:00pm Sunday: 10:00am – 4:00pm If you're unable to visit our showroom, selected mattresses are also covered by our 200 Night Trial, giving you the opportunity to try your mattress at home with complete confidence. Please check the product page for eligibility.
  18. Q:How is my mattress delivered?
    A:Delivery varies depending on the mattress you choose. Dormeo Memory mattresses are vacuum-packed for easy transportation and hygiene. You can find out more on our delivery page. Please refer to the product page for the delivery service included with your chosen mattress.
  19. Q:Can I use an electric blanket with my mattress?
    A:We do not recommend using an electric blanket with foam mattresses. Prolonged exposure to heat may affect the performance and shape of the foam over time and could invalidate your warranty.
  20. Q:What mattress firmness is right for me?
    A:The right mattress firmness depends on your preferred sleeping position, body type and personal comfort preference. Whether you prefer a soft, medium or firm feel, Dormeo offers a range of mattresses designed to provide the right balance of comfort and support. If you're unsure which firmness is right for you, explore our Mattress Buying Guides or contact our Sleep Experts for personalised advice.
