Responsive to you
The heart of this mattress holds 1500 Aerocoil® springs. Created from strong titanium, these springs are shaped to offer durability and bounce. Compressing against your weight in order to distribute support evenly. Freeing your muscles, back and joints from uncomfortable aches. You can experience a mattress that is tailored to your sleep position, movement and habits. These springs are excellent at reducing motion transfer, for an undisturbed slumber when sharing the bed.
Innovative foam
Exclusive to Simba, their Simbatex® foam delivers a blissful feel. Shaping around your body, the foam cuddles your contours. Helping you ease into your mattress and wind down into the cosiest slumber. This foam has been infused with graphite, allowing it to access open air flow. This unique feature ensures a cooler sleeping surface, ideal for hot sleepers.
Zoned support
Elevating the greatness of this Simba mattress further is the CertiPur® accredited foam. Split into 7 different zones, this foam targets multiple important areas. Supplying them with much needed support to soothe and relieve pressure. These zones take care of areas of your body that are vital, such as your spine, neck, hips, shoulders and muscles. This special foam has been accredited by CertiPur®, a certification programme, which ensures the foam being used is made with ozone depleting substances and has a controlled chemical usage.
Cosy up
Unwind after a long day and snuggle up against the knitted cover. Made from smooth and soft fabric, it offers a comforting feel. To keep it in great condition, make use of the removable feature and wash often to keep it clean. Simply unzip the cover and machine wash at 40 degrees for lasting freshness.

This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 nights. If it's not quite right for you, you can exchange it for a new one.
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're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.

So far it's the best mattress I ever had.At first when I first saw it in person I thought it was too hard and people were just posting fake reviews to boost sales but oh my god! when you try it there's a huge difference and there's no more back pains and it is a good sleep. It also looks nice

Matress is not very deep, and very uncomfortable. I have had to buy a thick Matress topper to make it more comfortable.
