Why should you choose this mattress?
The memory foam on top is there to cushion and contour, which suits anyone who likes to feel gently held rather than perched on the surface. Beneath it, the 1000 pocket springs form the supportive core, and because pocket springs move independently, they help keep movement from spreading across the bed. A medium-firm feel is a sensible middle ground that should suit most back and combination sleepers, although very light side sleepers may find it a little firm at the shoulders. Mattressman offers a 60-night sleep trial, which gives you time to decide, and the affordable level makes it easier to try.

FAQ's
How firm is the UNO Stellar 1000?

What sizes does the UNO Stellar 1000 come in?
It comes in UK Single, UK Double and UK King. If you need a Super King or a smaller size, this model isn't offered in them, so check the sizes before you commit.
How many springs does the UNO Stellar 1000 have?
It has a core of 1000 pocket springs, topped with memory foam layers. Pocket springs work independently, which helps with support and with limiting movement between two sleepers.
Does the UNO Stellar 1000 come with a trial?
Mattressman offers a 60-night sleep trial and free next day delivery on it. These are Mattressman's own offers rather than Uno's, so check the retailer's terms before you buy.

Uno doesn't publish a depth for this mattress. If depth matters for your bed frame or your bedding, check with the retailer before ordering.
