"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."



"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"



"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?
