Health

OEKO-TEX® 100 Standard certified fabric
The fabric on this Jay-Be mattress is OEKO-TEX® certified so you can be sure it contains no chemicals harmful to human health. 

100% Foam Free
All comfort layers are breathable, helping to enhance airflow and reduce moisture for a cleaner, fresher sleep environment.

The mattress fabric is treated with a natural, salt-based flame retardant (FR) that exceeds basic REACH compliance, offering a safer and more environmentally responsible alternative to traditional FR treatments.

Hypoallergenic materials

Sustainability

Award-winning and industry leading sustainability
Jay-Be is committed to promoting sustainability by incorporating responsible practices across its business. Each mattress is crafted using carefully selected, ethically sourced materials and is designed with end-of-life recyclability in mind.

Designed to be easier to recycle
Every component has been carefully chosen and assembled to make the mattress easier to deconstruct and recycle at the end of its useful life.

Zero to landfill manufacturer
Jay-Be is an independently audited and certified zero-to-landfill manufacturer, ensuring that all waste from its manufacturing processes is either recycled or recovered for energy, with nothing sent to landfill.

Recycled materials
Jay-Be incorporates recycled materials wherever possible to reduce reliance on virgin resources. The comfort layers in this mattress contain fibres made from a minimum of 70% recycled content.

Advance e-Fibre
This 100% Foam Free mattress features Jay-Be’s exclusive Advance e-Fibre™, made with fibres produced from recycled PET bottles. It has been proven to offer substantial environmental advantages over conventional cotton, including:

99% less water use*
99% reduced land use*
90% lower CO₂ emissions*

*Results are based on a cradle-to-gate Life Cycle Analysis (LCA) comparing Advance e-Fibre™ fibre with standard cotton fibre production. These findings have been independently verified. The analysis follows ISO 14040 and 14044 standards and reflects European manufacturing conditions, providing a robust comparison of key sustainability metrics.

Fillings sourced from a GRS-certified manufacturer
Jay-Be e-Fibre™ is supplied by a Global Recycled Standard (GRS) certified manufacturer, ensuring rigorous environmental and social responsibility standards are met.

Over 200 million plastic bottles recycled
Replacing foam with e-Fibre™ comfort layers has resulted in more than 200 million plastic bottles being recycled so far - and this number continues to grow. (as of March 2025)

Reduced packed size by 70%
This mattress is vacuum packed and rolled, significantly reducing its size for transportation, helping minimise storage space required, and emissions associated with delivery.
