Description
At the pinnacle of the Simba Natural Hybrid® collection, the Simba® Apex Mattress represents the ultimate in luxury, innovation, and support. Featuring twelve expertly engineered layers and an orthopaedic design, it delivers exceptional full-body comfort while helping to reduce everyday aches—transforming the way you sleep and feel each day.
12 layers of comfort and support for any type of sleeper
With up to 6,700 springs and a generous 32cm depth, the Simba® Natural Hybrid® Apex Mattress is crafted to provide deeply restorative sleep night after night. Available in double, king, and super king sizes, it’s an excellent choice for couples seeking uncompromising comfort and support.
Cashgora, silk, and wool layers add luxury, cushioning, and breathability
A premium blend of Cashgora and silk forms the top layer, offering soft, breathable cushioning with natural temperature regulation to prevent overheating. These fibres wick away moisture to keep your sleep surface dry and comfortable. Beneath, a layer of Hampshire wool and five additional layers of British wool enhance airflow, manage moisture, and provide plush, body-hugging comfort.
Adaptive pressure relief from durable British-made steel springs
Two layers of Aerocoil springs, crafted from resilient British steel, deliver responsive, targeted pressure relief by adapting to your movements. Working alongside the CoreMax base of full-sized pocket springs, these support layers provide deeper stability and create an orthopaedic level of comfort that helps ease pressure on your back and joints.
Wake up the best version of you with orthopaedic support
Designed to promote proper alignment of the spine with the hips and shoulders, the orthopaedic structure encourages a healthier sleeping posture. This reduces tension across the body, helping you wake up feeling refreshed, energised, and free from discomfort.
Glue-free construction and plant-based cover for a healthier sleep
The CoreMax base features a glue-free construction for a more sustainable design that’s better for both you and the environment. Finished with a plant-based viscose cover, the mattress offers enhanced breathability and a silky-soft touch. Naturally hypoallergenic, it creates a cleaner, healthier sleep space—ideal for allergy sufferers and anyone seeking premium comfort with peace of mind.
