  • Description

    Experience the unrivalled support, comfort and luxury of a Harrison Spinks mattress with the Knaresborough 3250 Pocket Ortho Mattress.

    Reassuringly firm and supportive, this ortho mattress is the perfect choice if you prefer a firmer feel and high levels of back care. It's exclusive to Mattress Online.

    Orthopaedic firm support

    This is the mattress for you if you love a firm feel. Thanks to the award-winning pocket sprung support, the Knaresborough will give you enhanced back care and better lumbar support.

    Looking for a medium-firm feel? Take a look at the Harrison Spinks Levisham.

    Generous pocket springs

    Harrison Spinks' expert Cortec™ Quad Core spring system lies at the core of this mattress. 3250 individual pocket springs are supportive and soothe away pressure points, for incredible comfort.

    Since each spring reacts independently, you'll get highly-tailored support for every area of your body.

    Support right to the edge

    Thanks to the expertly side-stitched borders, you'll get complete edge support across your mattress - and more space for the best sleep.

    Natural goodness

    Featuring a blend of Yorkshire wool, cotton, flax and hemp, this mattress is handcrafted from natural ingredients.

    You'll enjoy a plush sleeping surface with excellent temperature regulation through the seasons. It's a must during warm summers and cool winters.

    Sustainable fillings

    This mattress cares for you, and our earth. A supportive layer of eco-polyester provides extra comfort, and is made from 100% recycled materials. All the fillings can be recycled, too!

    Healthy slumber

    There's no foam in the Knaresborough. Plus, since wool is naturally fire retardant, it's fire resistant.

    Wool is hypoallergenic and antibacterial, so it's a great choice if you're looking for an extra clean, fresh feel.

    Easy care for busy lives

    There's no need to turn this mattress over - it's single-sided for easy maintenance. All you need to do is rotate it once every 6 months, using the robust turning handles.

    Eco-friendly delivery

    The Knaresborough will arrive rolled up, for super-fast delivery and easy installation. Simply unwrap and allow the mattress to expand. It'll be ready to sleep on in just a few hours!

    Since rolled mattresses take up less space, we can deliver more. This means we can reduce our carbon emissions and help protect our world.

    Reassuringly firm comfort

    Deeply supportive sleep can be yours with the Knaresborough. It's ready as soon as tomorrow!
