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.

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.

Extremely happy with this mattress
Extremely happy with this mattress - tried the medium initially but swapping to the medium-firm has been perfect. I have been receiving chiropractic treatment for 15 years and I finally feel like my back has the right combination for excellent sleep (with my Ecosa pillow).

Very comfortable and so easy
Very comfortable and so easy to swap between medium and medium firm. Also despite its weight the bed can still be shifted without too much effort.

Safe Sleep for Your Little One

The Ecosa Cot Mattress is made with a firm, flat sleep surface and complies with the AS/NZS Voluntary Standard for infant mattress firmness. It is also Red Nose Approved for Safer Sleep, having been reviewed against Red Nose Australia Safe Sleeping criteria.

A firm, flat surface helps support safer sleep for babies by reducing soft, sinking surfaces in the cot. Always follow safe sleep guidance by placing baby on their back, keeping the cot clear and using a mattress that fits the cot properly.

Breathe Easy With Advanced Airflow

The Ecosa Cot Mattress features a Nestflow™ core and 3D Mesh cover to help air move through the mattress. This breathable design supports ventilation while your little one sleeps.

The mattress is also thermoregulating, helping reduce heat build-up through the night. A cooler, more breathable sleep surface can help your baby rest more comfortably.

Certified Safe and Non-Toxic

The Ecosa Cot Mattress is made with safety in mind, using materials that meet recognised standards. It is Red Nose approved, compliant with the AS/NZS Voluntary Standard for infant mattress firmness, RoHS compliant and REACH compliant.

The mattress is also made without adhesives, latex or chemical fire retardants. That means a cleaner sleep surface for your baby, without the stuff you’d rather keep out of the cot.

Hygiene Made Simple

The Ecosa Cot Mattress is 100% washable, so cleaning up after spills, sweat and little accidents is simple. Remove the cover and machine-wash it according to the care instructions.

The Nestflow™ core can also be rinsed in the bath, shower or under a hose. Let every layer dry fully before putting the mattress back in the cot.

Lightweight and Portable Design

The Ecosa Cot Mattress weighs 9.4kg, making sheet changes, cleaning and cot setup easier. Its lightweight design is useful for parents who need to lift, move or refresh the mattress often.

The mattress measures 130cm x 69cm x 8cm and is made to suit standard cots. It’s a practical choice for everyday nurseries, shared rooms and families who like sleep gear that’s easier to manage.
