      Extra Firm Mattresses

      As glorious as sinking into a super soft mattress can be, if maximum support is what you're after, then a very firm mattress is almost certainly going to be a better choice for you.

        Quick customer service

        Update.Customer service got back to me organised a credit to my account to replace and delivered a new one the next day. I went for the soul sleep bliss 800 memory foam pillow top and now sleeping like a baby. Which recommended aswel with a 10 yr guarantee- research is key ordered the mattress checked reviews beforehand and all looked ok. Im assuming that most of these are done within the first week of buying the mattress because once its delivered and put on the bed. I brought a spring memory foam ortho mattress within one week I had back pain (never had this before and I always buy this type of mattress) within 21 days I started feeling all the springs underneath the very thin memory foam layer I followed all instructions re rotating top to bottom regularly. I am shocked that only after this small amount of time the springs and easily felt even when placing your hand onto the top layer. I emailed the help center and they got back within 48hrs requesting lots and lots of photos to send on to the manufacturer and said if they dont resolve it theres a 100 day mattress guarantee (but can only be enforced after 50 days to be able to exchange and there is a 100 delivery fee) so I have to wait another 27 days with a mattress that is causing extreme hip and back pain form the springs digging into me which is not acceptable. Please collect the mattress and refund my money I do not want another mattress from this site as I no longer have faith in your products

        Fantastic service

        Fantastic service, I researched mattresses for weeks & this one had great reviews and a long guarantee. It arrived very quickly, easy to unroll. Left it the required time and oh I wish I had purchased earlier. I have arthritis of hips, spine and knees & was waking every few minutes with pressure point pain. I dont suffer that at all now it went within a couple of days. I still have pain but not where my joints meet the mattress. I paid 404.00 with a mattress protector so not the most expensive mattress but worth every penny in fact it looks & feels way more expensive. Its a shame to cover it up with bedding it looks lovely!

      Help & Buying Guides

      What is an extra hard mattress?

      The sturdiest of the available UK mattress firmness ratings, extra hard mattresses offer enhanced levels of support that go above and beyond the kind found in a standard firm mattress or softer.

      With an exclusive focus on lumbar and neck support to help you drift off into a peaceful sleep and wake up feeling refreshed, these sorts of beds are the pinnacle of mattress orthopaedics. They're generally recommended for specialist support and might be recommended by your doctor if you suffer from chronic back pain.

      Why choose an extra hard mattress?

      While a cushy and bouncy mattress can be just what’s needed after a hard day’s work when you're younger, as you get older, you might find that you need a mattress with additional support to minimise back, neck, and shoulder pain upon waking.

      Alternatively, you might find that, as a heavier individual, a standard mattress doesn’t provide nearly enough support for your frame, making an extra firm mattress the perfect option for giving your body the support it needs in bed.

      Either way, if you're looking for specialist support with an extremely firm feel, then an extra firm mattress is the way to go!

      Is an extra firm mattress good for back pain?

      When it comes to back support in bed, the general rule of thumb is the firmer the mattress the better. This is because the extra support offered by a firmer mattress can improve the posture of your body while sleeping, aligning your spine and neck to reduce aches and pains upon waking.

      However, it’s best not to assume that a firmer mattress is going to be better for your back in all scenarios. For example, if you weigh under 150 lbs or 10½ stone, you may need the cushioning of a softer mattress. Likewise, if you weigh over 230lbs or 16½ stone and sleep on your front or back, a mattress that is too firm may actually aggravate pressure points.

      Therefore, if you want to find the best mattress for back pain, you need to test your chosen mattress before committing to ensure it provides the comfort you’re after—our Sleep Trial across all mattresses can help with this!

      What are the different types of extra-firm mattresses?

      Despite their super firm rating, extra firm mattresses are available in a variety of common mattress types, including classic pocket-sprung models, hybrid mattresses, foam varieties, and dedicated reflex memory foam options for extra material density.

      However, because of their supportive focus, extra-firm mattresses also come in a variety of orthopaedic mattress options, including those made with medical-grade foam for a blend of cushioned support.

      How firm is too firm for a mattress?

      Although the whole point of a very hard mattress is to increase the degree of support provided when sleeping, if you’re waking up on one with backache, bodily discomfort, or just generally feeling worse after a night’s sleep, then your mattress may be too firm.

      However, it’s worth noting that firm and extra-firm mattresses take some time to ‘break in’ and may start to feel softer after a couple of months or so. But if you still feel uncomfortable after this period, then you’re best buying a new mattress.

      Extra firm mattresses are much firmer than regular firm mattresses, and just because you might prefer a firmer feel doesn't mean your body is ready for the kind of hardness this type of mattress provides. These extra firm mattresses are usually reserved for people who need specialist support for their back and joints or have other medical issues that require this level of support.

      Will a firm mattress get softer?

      Yes, while designed with an enhanced lifespan in mind, even the hardest of mattresses will soften over time, though you can expect a very firm mattress to retain its rigidity far longer than a standard soft or medium mattress.

      How much does an extra firm mattress cost?

      How much an extra firm mattress will cost comes down largely to your mattress and bed size. For example, in the MattressNextDay range, you can find extra firm mattresses costing as little as £250, while our high-end models may cost £1,000+, it all depends on size, quality, and brand.
