At the most premium end of the Simba Natural Hybrid® range sits the Simba® Apex Mattress. With twelve meticulously crafted layers designed to offer you full-body support and comfort, plus an orthopaedic construction that sets you up for everyday, ache-free, this mattress is designed to elevate your sleep and improve your lifestyle.

12 layers of comfort and support for any type of sleeper

With up to 6,700 springs and a sumptuous 32cm depth, the Simba® Natural Hybrid® Apex Mattress is specially engineered to deliver the kind of restorative rest you can truly feel, night after night. And available in double, king, or super king sizes, this is one of the best mattresses for couples who never compromise on comfort.

Cashgora, silk, and wool layers add luxury, cushioning, and breathability

A top layer of luxurious Cashgora and silk provides soft, breathable cushioning, plus temperature regulation that prevents you from getting too warm. Wicking away excess moisture, these luxury natural fibres offer a drier, more comfortable sleeping environment that's as premium as it sounds. Beneath this is a layer of gentle Hampshire wool, plus five further layers of British wool. Offering exceptional airflow and moisture control, these wool keep you cool and fresh while hugging your body in intense comfort.

Adaptive pressure relief from durable British-made steel springs

For an impressively close level of support, two layers of Aercoil springs provide highly responsive pressure relief. Made from British steel, these small but strong springs adapt to your every move, targeting support exactly where you need it. Supported by the CoreMax base of full-size British-made steel pocket springs, which provide an even deeper level of support, these support systems create an orthopaedic level of comfort that helps to ease back and joint pain.

Wake up the best version of you with orthopaedic support

By helping to align your spine with your hips and shoulders, orthopaedic support encourages a healthier sleeping posture, in turn reducing tension throughout your body. The Simba® Natural Hybrid® Apex Mattress provides this essential level of support, helping you wake up truly refreshed and rejuvenated every morning.

Glue-free construction and plant-based cover for a healthier sleep

The CoreMax base is also crafted with a glue-free construction, which is better for you and the planet. This eco-conscious design goes hand in hand with the plant-based viscose cover that finishes the mattress, providing enhanced breathability and a silky soft feel. Naturally hypoallergenic, the Simba® Natural Hybrid® Apex Mattress is ideal for allergy sufferers or anyone looking for a healthier, more hygienic sleeping environment that provides incredible levels of support and comfort.
