With an array of prestigious awards under its belt, the Simba Hybrid® Ultra Mattress is one of the most innovative mattresses money can buy. Known for their impressive sleep technology, Simba have cut no corners when creating this highly supportive, intensely comforting mattress, filled with clever features that deliver your best night's sleep.

The highest-ever spring count of any Simba mattress, offering unparalleled tailored support

Their highest-ever spring count, this mattress features up to 7,300 supportive springs. Titanium alloy Aerocoil® micro springs sit in the upper layers of the Simba Hybrid® Ultra Mattress, compressing naturally to your body's movements. These springs are the size of a paperclip, meaning you won't be able to feel them, but they'll adjust accordingly to your changes in weight distribution throughout the night, offering tailored support.

An incredible selection of specially engineered springs for intense comfort & pressure relief

Up to 2,500 high carbon steel Aerocoil® micro springs sit further within the mattress to maximise support and push air throughout the mattress to provide a fresher sleep surface. A clever SupportCore™ base features up to 1,000 barrel-shaped pocket springs to provide an even more intense level of orthopaedic support, helping to keep your spine and posture aligned for a more comfortable sleeping position. A CertiPUR® foam base complements this base to enhance stability.

Layers of innovative materials designed to provide impressive cushioning

 In the centre of the mattress, you'll find a stabilising core foam layer, which maintains the structural integrity of the mattress and enhances airflow. Interestingly, you can also find a support-boosting PureLift™ layer, made from a blend of latex and coconut for elasticity, offering you a gentle, comforting bounce. Above this, you can enjoy the benefits of two layers of renowned Simbatex® foam, which gently moulds to your body for personalised cushioning and pressure relief.

Natural fibres sourced from around the world, including the rainforests of South East Asia

Not stopping there, this mattress also features an innovative FusionCool™  layer, made from a unique blend of wool, bamboo, charcoal, and kapok. These natural fibres have been sustainably sourced, with the insulating wool coming from Hampshire, England, and the Kapok from the rainforests of South East Asia. These fibres provide indulgent cushioning and enhanced airflow, complemented by the soft, breathable cover, which features Simba's 'cool-touch' Stratos® tech to offer you an instantly cooling sensation. This cover can even be easily zipped off and machine-washed to keep the Simba Hybrid® Ultra Mattress as clean, fresh, and hygienic as possible.
