Enjoy reliable, long-lasting support with the Sealy Columbia Ortho Firm Support Mattress, designed for sleepers who prefer a firmer feel and enhanced pressure relief. Made exclusively for Bensons for Beds and crafted in the UK, this orthopaedic mattress combines advanced support technology with breathable comfort for a healthier night’s sleep.

At its core is Sealy’s PostureTech Core Support spring system, delivering pressure-relieving support that gradually firms up as weight is applied. This responsive design helps to maintain correct spinal alignment while reducing pressure on key areas of the body.

Targeted support comes from the central zoning PowerPack, offering additional reinforcement where it’s needed most. 

Finished with a luxury Belgian damask cover, the surface feels soft yet durable, while Smartex® fibres actively regulate body temperature to help keep you cool, dry, and comfortable throughout the night. Inside, ReNew fibres, made from 76% recycled PET plastics, enhance airflow and breathability while supporting a more sustainable sleep choice.

For a cleaner, healthier sleep environment, the fabric is treated with ProShield®, a natural anti-allergen technology endorsed by Allergy UK, helping to protect against allergens.

Designed for durability and comfort from edge to edge, EdgeGuard technology reduces roll-off and maximises the usable sleep surface. The mattress is hand-tufted for a supportive, traditional feel and is easy to care for, requiring simple regular rotation without the need for turning.

With a firm comfort rating, a 27cm depth, and a free 5-year guarantee* for peace of mind, the Columbia Ortho Firm Support Mattress is a dependable choice for those seeking structured support and long-lasting comfort.

Also available in an extra firm option as the Sealy Columbia Ortho Extra Firm Support Mattress.
