Sleeprite Ortho Posture King Mattress

The Sleeprite Ortho Posture King Mattress is designed around a structural innerspring system and sized generously at a full 183 x 203cm, this king mattress gives your body all the space and all the support it needs to rest in a naturally aligned position through every hour of the night. Arriving rolled and compressed in a compact, easy-to-handle box, this king mattress is far more manageable to bring home than its generous dimensions suggest. It moves through doorways without stress, sets up without any professional help, and expands into a full, substantial king sleep surface that feels purposeful and well considered from the very first night you lie down on it. 

The structural innerspring core works quietly and consistently through the night, keeping your spine in its natural alignment and easing the tension that builds up in your back, hips, and joints through a busy day. Even weight distribution across the full 183cm king width ensures no uncomfortable pressure points developing as the hours pass, allowing your body to fully relax and recover in the way that genuine restorative sleep requires.
