Questions & Answers

  • What size mattress do you need for a double bed?

    A double mattress measuring 4’ 6 x 6’ 3” (135cm x 190cm).

  • Can two adults sleep on a double mattress?

    Yes, a double mattress sleeps two adults. However, we do not recommend this size for couples who share the bed with children or pets, as space will be limited. For ample space, choose the largest bedframe and mattress that fit your floor space.

  • What is the best double mattress?

    The ‘best’ is one that suits your own needs and is within your budget. Look out for the expert choice awards on our website. These are highly commended products that have been found by our panel of bed experts. Further help is on hand from our bed experts who will be able to help you find the best double mattress for you at the greatest possible price.

  • What should I look for when buying?

    Price, mattress type, comfort grade, room size and sleep needs should all be considered when making a purchase.

  • Which one is right for me?

    Choosing the "right" mattress varies based on preferences and needs. Visit our stores to test each mattress. If not, consider your sleeping position, body type, and preferences (soft, medium, firm). For details, check our guide: "How to Choose the Best Mattress for Me."

  • How much should you pay for a double mattress?

    The cost of a double mattress in the UK varies based on the type you choose and your budget. Cheap double mattresses are typically made with open coil springs and are quite traditional. They offer good comfort and support when well maintained. You can find a double mattress of this kind for around £150.

  • How often should I replace my double mattress?

    The National Bed Federation recommends replacing your mattress every 7-8 years. But it's not just about time. If you notice sagging or springs poking through, it's time for a new one. Weird noises or creaks when you move also signal replacement. Using a mattress protector can help keep it clean and fresh longer, protecting your investment.

  • Will it fit in my boot?

    Please note that most cars aren't suitable for transporting mattresses, which could void your warranty if mishandled. Let us handle the delivery hassle for you! Enjoy free mainland UK delivery for orders over £100. For orders under £100, a small fee (starting at £10) applies. Additional charges may occur for remote areas or the Highlands—check your postcode at checkout.

  • Can I buy on finance?

    Yes, you absolutely can get and we have a variety of interest-free credit and pay monthly options to help you do so.- How big is a double mattress compared to a small double mattress?
