4ingenious things about the Simbatex® Foam mattress

Find out how we use our knowledge and advanced technology to help you sleep better.

Simbatex Foam Technology

Traditional memory foam

Cooler, fresher

Our Simbatex® foam has an open cell structure which offers superior support and elasticity, as well as allowing 30 x more airflow than dense, standard memory foam. We also infuse it with natural graphite, which has an excellent ability to draw away excess heat.

  • Anti-allergenic, removable knitted cover
  • Cooling, cushioning Simbatex® comfort layer
  • Supportive Simba-Response foam layer
  • Zoned, high density foam base

Four layers of
engineered comfort

A harmonious quartet of technologically advanced materials to help you achieve deep, restorative sleep.

Anti-allergenic, removable knitted cover

A zipped, breathable cover, free from harmful substances (Oeko-tex 100 Standard) and suitable for allergy sufferers.

Tested & trusted
CertiPUR® foam

Better for you, better for your home



CertiPUR® Verified

CertiPUR® Verified

All the foam we use is CertiPUR® recognised, meaning both the materials it contains and the emissions it releases have been independently and rigorously assessed; it’s verified as free from CFCs and other ozone depleting substances, and ensures lower emissions to protect indoor air quality.

CertiPUR® foam is also free from added phthalates and harmful metals such as mercury or lead, and includes safe, non-toxic levels of fire retardants.


A sustainable

For Simba, protecting the planet is as important as restful sleep. We’re proud to be the first UK-born sleep brand to be awarded certified B Corp™ status.

Our official B Corp™ accreditation is an accolade that is only awarded to select businesses that promote social and environmental change through how we work and operate, something we consistently strive for.

We’ve used our knowledge to reduce our use of energy and materials, and all our mattresses are 100% recyclable. So any Simba mattresses that are returned to us are either refurbished or recycled. We also recently opened our own state-of-the art, non-for-profit recycling service and accept any brand of mattress with no purchase necessary to use the service.

All Simba mattresses are made in the UK in zero waste factories, reducing air miles in the process. Any leftover foam is used as carpet underlay or pet beds, and all our packaging is up to 60% recycled or from approved FSC sources.

All of our deliveries are 100% carbon neutral. We have worked hard to measure all of the emissions we create and as a result have offset all greenhouse gas emissions for customer deliveries.
