If you’re looking for a supportive and comfortable sleep, on a mattress that’s made up of multiple layers offering great benefits, then take a look at the Sealy Columbia Ortho Extra Firm Mattress.
Having the right mattress can be beneficial for keeping you supported as you sleep. The Sealy Columbia Ortho Extra Firm mattress is built with a PostureTech core support spring unit that offers technology to support the body where it’s needed the most.
Acting as the engine room of the mattress, the spring system helps to provide the firm and extra firm comfort that the Sealy Columbia Ortho Extra Firm has to offer. As you lay on the bed, the springs gradually get firmer as pressure increases to provide deep down support and pressure relief whilst you sleep. Twice tempered, the spring system is durable, responsive and will remain supportive throughout its life span.
In the lower back area of your mattress (or the lumbar area if you want to be scientific), you’ll get additional support thanks to the mattress’s central zoning PowerPack. This power pack provides extra support to your lower back and acts as a shock absorber to ensure the longevity and durability of the mattress.
We’re sure the majority of us would love extra sleeping space (we know we would!). Thankfully, this mattress has EdgeGuard – a Sealy technology that makes the edge of the mattress firmer. By having a firm edge, you get a larger sleeping area, meaning you can lie right to the edge of the mattress without feeling like you’re going to fall off. This gives you a larger sleeping space so you and your partner can move around freely without disturbing each other.
Covering these layers of comfort is a luxury Belgian damask cover that has been treated with skin-safe ProShield®. No one needs the annoyance of allergies popping up and disturbing them as they sleep. Pro-Shield is a skin-safe treatment, endorsed by Allergy UK, which can keep pesky allergens at bay, so you can have a clean, comfortable and restful night’s sleep.
