Sleeprite Ortho Posture Double Mattress

The Sleeprite Ortho Posture Double Mattress is built with its purpose in mind, delivering a structured, orthopaedic sleep surface across a full double size that takes proper care of your spine and your comfort from the moment you lie down. Arriving rolled and compressed in a compact, easy-to-handle box, this mattress brings a refreshingly uncomplicated experience to what is one of the most important purchases you can make for your bedroom. It moves through doorways without difficulty, sets up without any specialist help, and expands into a full 137 x 188cm sleep surface that feels solid, supportive, and genuinely well made from the very first night you sleep on it. 

At a generous 30cm deep, it fills a standard double bed frame with a presence and quality that makes your whole bedroom setup feel properly considered and complete. The orthopaedic design makes this mattress a particularly thoughtful choice for anyone who wakes up feeling stiff or uncomfortable on a mattress that does not provide adequate structural support  or for a guest bedroom where you want visitors to sleep well and wake up feeling genuinely rested.

Usage Tips

Styling and Practical Tips for the Sleeprite Ortho Posture Double Mattress

• Allow 24 to 48 hours after unboxing for the mattress to fully expand to its complete double size shape, depth, and feel before the first night of sleep on it.
• Rotate the mattress every three to six months to encourage even wear across the full double surface and extend the working life of the innerspring system over time.
• Use a quality double size mattress protector from the very first night to keep the surface clean and protect the mattress throughout its warranty period and well beyond.
• Ensure your double bed base or slat system provides consistent, even support across the full 137cm width  proper base support will protect the innerspring core and maintain the orthopaedic performance of the mattress over time.
