    Sleep well and wake ready to seize the day with the Sealy Activsleep Ortho Extra Firm Mattress!

    Part of Sealy's Activsleep range, this super-firm, orthopaedic mattress is a great choice if you love a sturdy feel and plenty of support to care for you as you sleep.

    Featuring Sealy's PostureTech Zero Deflection, this high-performance spring system delivers total body support. It helps prevent the transfer of movement across the mattress, so you'll get a completely undisturbed sleep. Durable and resilient, Zero Deflection provides truly extra firm support.

    This isn't just a mattress that delivers super-firm support. It feels plush and comfortable too! The smooth, knitted cover envelopes the Ortho Extra Firm and it's hand-tufted to lock in the fillings for enhanced durability.

    Working around the clock, a winning combination of Purotex and Adaptive® technology ensures a clean and healthy sleeping environment for you as you sleep.

    Infused within the cover, tiny microcapsules containing Purotex probiotics are released - preventing the build-up of nasties like dust mites and bacteria. It's hypoallergenic and approved by Allergy UK, so you can rest easy.

    Working in harmony with your body temperature, Adaptive® technology monitors moisture levels to keep you feeling cool, fresh and dry.

    As it's a single-sided mattress, you'll never need to flip it over. Instead, simply rotate from end-to-end to keep it in excellent condition.

    One of Sealy's firmest and most supportive mattresses, choose the Activsleep Ortho Extra Firm and get the great night's sleep you've been waiting for.

    Please note: the cover of your new mattress may be different to the one shown. Don't worry - you'll still get the same great mattress!
