Don’t Sweat It

Stay cool and sleep comfortably with Ecosa’s breathable open-cell foams, pin-hole natural latex and pocket springs — cleverly working together to regulate temperature, improve airflow, and help prevent overheating all night, every night.

No Partner Disturbance

Bed buddies can sleep soundly thanks to individual pocket springs and dense comfort foams, designed to absorb movement at the source. Each spring moves independently, so if one of you moves, the motion won’t be felt across the bed.

Frequently Asked Questions

Firm mattresses are best suited to dedicated back sleepers, or those who require an extra firm mattress for various reasons.
Aside from one being firmer than the other, the difference between a ‘medium-firm’ or ‘firm’ mattress comes down to personal comfort preference. Both offer the supportive benefits of an adaptive, firm sleeping surface. It’s up to you which one feels better.
The best part about our adjustable TrueFirm Mattress is that you have both, so you can try each side and sleep on the one best suited to you.
Simply try your mattress for 100 nights. If you don’t love it, we’ll refund you and arrange for it to be collected and donated to one of our charity partners. For more information, please visit 100-Night Trial
