"We had been looking for a mattress for about a year, but after much research I stumbled across Una. I have waited a year to see if the comfortable bliss we found when sleeping on their mattress would subside and all I can say is it has been the best money we've ever spent. So much so I bought their pillow for my husband who now sleeps like a log."


Trustpilot Review

"Without doubt the best thing I have purchased in decades. This is money well spent. The mattress is so comfortable, and it feels just as heavenly to know it is made from such amazing materials. Amazing team at UNA too. Thank you so much; I love it and so does my sleep"


Trustpilot Review

"Brilliant mattresses, firm yet forgiving, much more comfortable than so-called memory foams or contour-hugging mattresses, and they just FEEL great... they have that X factor that makes you really enjoy lying on them."

Better For The Planet Too

As well as being healthy for you, your Una is kinder to the environment. There’s no need for yucky petroleum based foam, industrial glues and the harmful footprints they leave behind. The latex in your Una is simply tapped from groves of organic certified Hevea trees, fighting climate change in the process by absorbing carbon dioxide from the air every day. And who needs polluting (regular) cotton or polyester covers when an organic certified, pesticide-free wool and cotton cover does a superior job naturally?

Frequently Asked Questions

Are there any chemical fire retardants, glues, synthetic foams or other additives in an Una Mattress?

An Una Mattress™ is a pure as can be containing ONLY the finest natural sleep materials namely organic certified natural latex foam (in 3 firmnesses), organic cotton, organic wool.

How do I personalise/configure the firmness of my Una Mattress?
Una is the world’s first organic optimizer mattress which means you can tweak the firmness of this amazing natural mattress to perfection. For extra softness have the soft on top the medium in the middle and the firm at the bottom. If you need some initial softness combined with firmer support then try soft on the top, firm in the middle and medium at the bottom. For a medium feel put medium on top soft in the middle and firm at the bottom. For a firm feel have the firm on top medium in the middle and soft at the bottom or medium on top and firm in the middle for a medium-firm feel. Side sleepers and light body types tend to need a softer feel. Front and back sleepers and heavier body types tend to need a firmer feel for a perfect spinal alignment. Your personal preference is also important of course ? Just unzip your cover, roll up and remove the organic foam layers and unroll them back inside the cover in the order you want them. Roll it, Zip It, Love it. Do it with two people, it’s that simple.
