Plenty of people walk into Bensons wanting an Eve hybrid in its simplest, slimmest form, and this is the mattress they come to. The Hybrid Uno is pocket springs under a layer of memory foam, made in the UK, rolled up for delivery and sold only at Bensons. It sits at the bottom of the Eve hybrid ladder there, one rung below the Hybrid Duo and two below the Duo Plus, and its job is to put a proper pocket-sprung hybrid within reach of a tight budget. I tried both Eves at Bensons in October 2026, the Uno and the Duo in one visit, so I know how close the pair come. On your side, your shoulder settles into the foam, then the springs catch you and keep you there.
It suits a light or average-weight side sleeper who is watching the pennies, and it suits a guest room that gets regular use. For a spare room it's the sort of mattress I'd pick: pocket springs, a medium feel that most visitors can sleep on, and light enough to drag about when you change the sheets. Where it falls short is depth. At 23.5cm it's a slim mattress for a hybrid, and there's less padding between you and the springs than on the Duo. If this is the bed you'll sleep in every night, buy the Duo. Front sleepers should skip it, and so should anyone who likes to sink deep into a mattress.
Enough give at the shoulder, with the springs close underneath
I'm a 61kg side sleeper, and on my side the Uno gave enough at the shoulder, which is the first thing a medium has to get right for anybody built like me. On my back it was comfortable for a medium bed. On my front it was a little less comfortable, though front sleeping is the position I'd talk most people out of anyway. What stayed with me was how near the springs felt. You go through the memory foam quickly, and the pocket springs are right there under it.
A second tester of ours tried it in a Bensons store in July 2024, at 86kg and moving between back and side. On their back they found ample support with a medium feel, on their side the foam contoured at the hip and shoulder, and the edge held firm enough to spread out across the full width. So we agree it supports. What I noticed on top of that was how close the springs sit under the foam.
That's what a slim build does. With 23.5cm to work with, the foam on top can't be deep, so you feel the springs sooner than you would on the Duo's 28cm. Like to sleep on top of a mattress with a bit of spring under you? You'll get on with this. Like to sink in a little further before anything pushes back? That extra depth is exactly what the step up to the Duo gives you. A light side sleeper gets the gentlest version of the Uno, and an average-weight back sleeper gets the ample support our 86kg tester found.
The Duo's build, made slimmer
Underneath, the Uno is put together to the same standard as its deeper sibling. There are 1100 pocket springs, every one wrapped separately and free to move without dragging its neighbours, under a layer of CertiPUR-certified memory foam and a soft stretch-knit cover. Bensons adds edge support round the spring unit, which you'll be glad of when you perch on the end of the bed to get dressed. It's made in a BSI Kitemark-accredited factory, and that counts for more with me than any award on the label. Bensons also says the sleep surface is naturally fire-retardant, so nothing chemical is added to it to pass the fire rules. I note that and move on. Any mattress on sale here has had to pass the fire rules anyway, and the route this one takes is a pleasant extra rather than a reason to choose it.
A spring count around a thousand is light by my reckoning. These are proper pocket springs, though, and they do their job. What separates the two Eves is something else. The Duo is deeper, adds a layer of mini springs over its full-height ones and puts a quilted cover on top, so there's more between you and the main springs. Mini springs often pad out a spring count more than they change the feel, but here the step up is honest and you can feel what it adds: the depth this one is missing. The Uno is one-sided, so you rotate it head to foot and never turn it. I'd always choose a mattress you can flip, since it lasts longer. Here rotating is the upkeep that works, as long as you remember it.
Owners put it in kids' rooms and spare rooms
Read what owners say and a pattern shows quickly: a lot of these mattresses go to children, teenagers and guests, and the parents and hosts report happy sleepers. That fits what the build is good at, because a light body gets all the give it needs from that layer of foam. One owner had worried it would be too thin and wrote that it's "got fantastic support" instead. Another preferred it to the Duo because it feels a bit firmer, which is when I'd choose the Uno over the Duo for your own bed: you're average weight, you want a firmer medium and you lie mostly on your back or side.
The complaints are worth knowing too. Most owners call it medium to firm and just right, and a few find it hard, one of them comparing it to "sleeping on a rock". The odd owner wakes up warm on it, which is the memory foam on top, so anyone who sleeps warm should look for natural fillings instead. And the care instructions ask for more rotating in the first weeks than some owners expected. Do it anyway, because spreading the wear early is what keeps the top even.
Getting it home
It comes rolled and vacuum-packed, and owners keep saying how easily it went up awkward stairs and into a loft room. I've recently moved, and a rolled mattress is the easiest kind to get through a new front door. Most owners had it at full size within hours, while a few found a corner slow to fill out and gave it a day or two, so leave it a full day before you judge the feel, and open a window while it airs. You can collect one from a Bensons store and fit it in most cars, and the sizes run from single to king, with no super king.
Owners have it on divans, ottoman beds and slatted frames, and all of those work. On slats, measure the gaps first. Anything wider than roughly seven centimetres lets a slim mattress like this sag between them, so the slats are where I look before I blame the mattress for a dip. One owner said as much, warning against wide, badly made slats.
If it turns out wrong for you, the 40 Night Comfort Guarantee lets you exchange it once you've slept on it for a few nights. You need to have used a mattress protector, and there's a charge, so ask what that is before you buy.
Why the Duo is worth the step up from the Uno
For the bed you sleep in every night, buy the Eve Hybrid Duo. It's the same kind of build with more of it: deeper, with a second layer of springs and more padding over the top, and it's the one I preferred of the two. Most people should make that step up.
If your budget stops at the Uno, it's still the bed I'd take from that end of the Bensons floor, ahead of the Simply Memory Foam Pocket Sprung Pillowtop. That one puts a pillow top over 800 firm springs, and a pillow top is worth weighing for long-term wear. The Uno gives you more pocket springs and foam with no top to think about.
