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
Choose Solid Ergonomic Support with an Extra-Firm Mattress
If you find comfort in a sleep surface with an ultra-firm and stable feel, an extra-firm mattress may be the right choice. With robust support systems and materials such as high-gauge springs, high-density foams and latex, these mattresses are designed to provide a solid surface with little to no give.
Not a fan of the sensation of melting into a plush, cushioned mattress? An extra-firm mattress won’t disappoint. Unyielding under pressure, they prevent the body from sinking and have a flat and firm feel with minimal contouring.

Is an Extra-Firm Mattress for You?
Mattress comfort is a matter of personal preference, and many extra-firm mattress fans simply prefer a harder sleep surface. However, there are some other reasons for sleepers to swap to super-firm support.
Firmer mattresses are often recommended for back pain as they promote neutral spinal alignment and prevent sinking in the hips and lower back. For this reason, an extra-firm mattress is a suitable option for back and stomach sleepers. Compressing less under body weight, an extra-firm mattress is also considered a good option for heavier sleepers.
Side sleepers, on the other hand, will usually benefit from the hip and shoulder cushioning of a softer mattress.
Struggle with a tossing, turning partner? Extra-firm mattresses are a great choice as they offer excellent motion isolation. They are also known for their durability, thanks to the use of higher-density foams.
