For the highest standards of quality and safety
The Simba Natural Hybrid 4800 Wool Mattress brings new, smart and comfortable innovations right to your bedroom with its unique CoreMax™ springs and sumptuous natural fillings.
Innovative features
There is no end to the brilliance of Simba’s creations especially with the introduction of their CoreMax™ springs. Designed with seven zones, these springs do not create a ripple effect throughout the mattress. Limiting the effects of motion transfer that can cause a disturbed slumber, particularly when sharing the bed.
Unique design
This mattress features special and exclusive Aerocoil® micro springs. Holding two layers of 1900 micro springs within its core, this mattress is highly supportive. Shaped in a cone design, these springs easily compress into a compact shape. Allowing them to deliver a greater bounce-back feel that instantly lifts pressure off your body.
Heavenly blend
Stacked in delicate layers within this mattress are six rows of natural British wool fibres. Wool is highly renowned and loved for their unique moisture wicking abilities. Helping to excellently limit mould and mildew build up for a more hygienic sleep. Winner of the Tom's Guide Editors Choice award, this mattress is praised for the move towards sustainable comfort filling.
Wool fibres have a gentle bounce which allows them to lift pressure off your joints. Allowing your body to sink-in and experience a weightless, pressure relieving feel. Highly durable and resilient, these fibres are a sought after addition within mattresses. Both an insulator and extremely breathable, wool layers offer perfect seasonal use.
Cooler comfort
The borders of this Simba mattress have been smartly crafted with an open structure. This means they feature pockets in their design that encourage airflow. The space for air to flow freely directly dispels heat particles within the mattress. Brilliantly keeping your mattress feeling fresh and cool, perfect for hot nights.
Easy care
Designed to be single-sided, you don’t have to worry about flipping this mattress. Simply rotate head to toe on a monthly basis. Keeping up with a rotation routine can aid in extending the lifeline of your mattress.
Achoo no more
There is no end in sight for the luxury of this Simba mattress. Created to be completely hypoallergenic, it is the ideal choice if you suffer from allergies. This includes hayfever, dust mite allergies and sensitive skin. Rest peacefully, undisturbed by unwanted sneezes, persistent itching and other irritating symptoms. A restful sleep is the true, indulgent luxury that you deserve.
Trusted construction
Simba’s mattresses meet the highest safety and quality standards. The company is also brilliantly B Corp certified, having undergone months of in depth analysis to showcase their successful efforts towards making a better impact on the environment. Letting you know you are choosing the right people to trust as they make strides in creating a more sustainable and happy future for you.

This mattress comes with a free 60-night comfort trial - like all of our mattresses!
The trial allows you to test your mattress for 60 nights, and if you don't like it, you can swap it!
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you don't like the feel of your mattress after 30 nights, simply get in touch! We'll be happy to swap it for you.
