Get a good night's sleep with Portland King Sponge and Spring Pocket Sprung Mattress. A 22.5cm thick hybrid mattress is designed for all sleepers for better sleep. Three-layer sponge and pocketed innerspring hybrid construction reach a balance between firmness and softness, providing extra support and more releasing pressure points. The soft mattress is supported by hundreds of individually pocketed springs. The innerspring works independently and can effectively absorb sound and vibration, and evenly distributed body weight provides excellent cushioning pressure relief. You and your partner can enjoy a quiet sleep without disturbing each other. The mattress cover is made of knitted fabric that is breathable and kind to your skin. The quilted cover adds thickness and softness to the upholstery while keeping the layers below from moving out of place. The mattress is compressed and rolled into a box for convenient transportation. Dimensions: 200 x 150 x 22.5cm.
