Snuggle up on the ultimate orthopaedic support mattress from Sealy. The Sealy Millionaire Ortho Ultimate Mattress lives up to its name, delivering outstanding support from the unique PostureTech Zero Deflection spring system, while giving you millionaire-lifestyle levels of comfort thanks to the luxurious tufting and ultra-soft filling.

PostureTech Zero Deflection Spring system

Using a unique design and spring matrix, the PostureTech Zero Deflection Springs minimise movement and weight transference to avoid disruption during sleep. That means a better night’s rest for you and your partner. The strong design also stabilises the sleeping area, delivering firm but comfortable support and minimising pressure spots on the shoulders, lower back, and hips.

Orthopaedic support for extra comfort

If you suffer from back pain and need a firmer mattress that doesn’t compromise on comfort, the Sealy Millionaire Ortho Ultimate Mattress fits the bill perfectly. It has a firmness rating of 5 making it suitable for those who prefer a much firmer feel. At 23cm deep, you get plenty of mattress for your money, and as a single-sided design you don’t need to flip and turn it, either, just rotate it head-to-toe occasionally using the strong turning handles.

Smart fibres keep allergies at bay

Sealy mattresses use a special Smart Fibre filling that helps you stay cooler and fresher while keeping those allergens at bay. That makes it perfect for asthmatics or anyone suffering from allergies, and the mattress is endorsed by Allergy UK so you know it’s safe. On top is a beautiful damask cover that’s breathable and durable, making it easier to keep clean and extending the life of the mattress.
