My new mattress is so unbelievably comfortable.
I wake up fresh and with energy. I'm not waking up to my partner rolling over either! The washable cover is such a bonus feature.

Best sleeps ever!
Never realised just how bad my sleep was until I got the Pure. It took a couple of weeks to adjust to it but now I sleep so well I can’t believe I have waited so long to get one. No sore back from a mattress that was too soft. Best buy, totally recommend.

Sleep Like a Dream on the Pure Mattress by Ecosa!
I recently had the chance to try out the Pure Mattress by Ecosa, and let me tell you, it's been a game-changer for my sleep! I love that I can adjust the firmness to my liking, so I can customise my sleep experience.
Verified buyer
Highly recommendable!
Best mattress I've had so far and I've had a few... My wife was a bit unhappy first but after a while she agreed and we both sleep well and wake up without back pain. Also: best customer service I've had so far. Ecosa certainly goes way beyond selling stuff - seems to be a concept that makes great products.

Frequently Asked Questions
Enjoy Solid Support with a Firm Mattress
With less give under pressure than softer mattresses, a firm mattress provides a solid foundation for a good night’s sleep.
Unlike plush mattresses that use additional comfort layers for a cushioned sensation, firm mattresses rely on high-density foam or latex, high-gauge springs and robust support systems to create an ultra-stable surface and prevent the body from sinking.

Why Choose a Firm Mattress?
Sag-resistant and durable, firm mattresses promote even weight distribution and help to maintain correct spinal alignment for peaceful, pain-free sleep. As a result, they’re often recommended for back sleepers, heavy individuals and those with lower back pain.
However, comfort preferences are personal, and other sleepers may simply prefer the feeling of a firm, non-yielding mattress.
