Complete Customisation

Based on 15 years of collaboration with expert engineers and vast customer research, the Dormeo S Plus Memory Foam Mattress has been designed to be the first 100% personalised mattress, offering over 30 different comfort combinations*. 

1. Choose your Side

The smartly connected cores, personal to each side of the mattress, can be quickly and easily interchanged, making the S Plus mattress a risk-free choice for couples with different sleeping preferences.

2. Choose your Comfort

Unzip the cover and flip your side of the mattress to choose between two unique Ecocell® foam densities.  You have the option of a softer side, suited for side sleepers, or a firmer side often favoured for those who sleep on their back.

3. Choose your Support

Rotate your mattress head to toe to find your preferred side of the unique S-shaped Octaspring® layer. Choosing to have the Octasprings closer to your neck and shoulders offers more adaptability and bounce. Alternatively, rotate the mattress horizontally to add distance between the Octaspring® layer and your neck and shoulders for firmer support.

Body Zoned Octaspring Technology

The Octaspring® is a next-generation, patented sleep technology, which delivers up to 8 times greater ventilation compared to traditional foam. This means you get a cooler, fresher night's sleep, while also providing incredible comfort and support.

Whilst the unique Octaspring® technology offers unrivalled breathability, the individual springs within the Dormeo S Plus Memory Foam Mattress are arranged in different firmness levels. This creates customised body support zones that are beneficial to correct spinal alignment for a better night's sleep.

Next Generation Ecocell®

Our uniquely breathable Ecocell® foam is what makes the Dormeo difference. The Ecocell® foam encases the unique Octaspring® tube technology, providing extra support. Ecocell® is a next-generation foam designed to be permanently elastic with a 3-dimensional cellular structure, providing efficient air circulation and support where you need it.

Anti-bacterial, Anti Dust Mite

A luxurious quick-drying Climalite Silver cover tops off the S Plus mattress, keeping moisture at bay for enhanced mattress freshness, whilst the Clean Effect treatment delivers anti-bacterial, anti-dust mite and anti-static protection.

    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 can arrange for your old mattress to be collected when your new one is delivered on selected orders. Please contact our Customer Care team before placing your order to check availability, pricing and whether the service is available in your area.
  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.
