There's more mattress here than the money suggests, and that's the entire case for it. Buy it for a spare room, a first flat or a teenager who is going to grow out of it anyway. Heavier sleepers should skip it: 1,000 pocket springs under 20cm is not much bed to hold a heavy body up, and no amount of goodwill changes that.
Pocket springs at this money is the whole point
Down at this end of the market your money usually buys open coil, where the springs are wired together and pass every movement across the bed, or a slab of foam. This one gives you a thousand individually pocketed springs, and that's worth more to me than anything else on its spec sheet. Memory foam sits on top and foam blocks are built round the border to firm up the edge. Nobody publishes how thick that foam layer is, so ask before you order if cushioning is what you're after.
Twenty centimetres is thin, and I get suspicious under about that depth, so this sits right on my line. Uno is Breasley's own mattress brand, which the listing never mentions. It's made in the UK, approved by the National Bed Federation, and the cover comes off and washes, which is genuinely handy on a bed a teenager will own. The hypoallergenic wording is a word on a label with no scheme named behind it, so give it nothing. The washable cover is the useful part.
The label and the description can't agree with each other
Don't buy this one expecting a soft bed, because nobody selling it can tell you what it is. The badge and the spec table say Soft to Medium. The retailer's own description, further down the same page, calls it medium and ideal for most sleeping positions. Every brand runs its own firmness scale and none of them travel, which is a state of affairs I find maddening enough without a listing contradicting itself in two places.
The owners don't settle it either, and there are only a handful of them, so read them as a hint and not a verdict. One bought it believing it was soft and found it hard. One wanted softer and got exactly that. One lands on calling it a medium. Worth knowing: the happiest of them put toppers on top, so part of what they're praising is cushioning they bought themselves. Use the trial, lie on it in the position you actually sleep in, and judge it yourself.
A second bed, not a first one
Avoid it if you're a heavier sleeper, if you want a mattress you can turn instead of only rotating, or if you need a superking, because the sizes stop at a king. For the guest bed in our spare room, mind you, that list of compromises reads very differently: nobody's on it three hundred nights a year.
It arrives rolled and vacuum packed, so getting it up the stairs is easy. Give it the full expansion time on the packaging, air the room while it recovers its shape, and ignore how it feels on night one. It's single-sided, so rotating it regularly is all the upkeep it asks for. The retailer never pins the interval down beyond every few months, so pick one, put it in your phone and stick to it. One owner says it's light enough to shift on their own. The 100-Night Comfort Trial buys an exchange and not your money back, needs one of the retailer's own protectors bought alongside it, and wants a month of sleeping on it first.
What to buy instead
If this is going to be somebody's main bed and not a spare, spend a little more on the Bodyshape 1000 Pocket Hybrid from the same retailer. Same spring count, same foam-over-springs idea, and a medium-firm grade you can actually plan around instead of two grades arguing on one page. Keep the Nova for the room nobody sleeps in every night.
