It is two mattresses for the first moment and one after that. Your shoulder and your hip press into the memory foam on top, then the pocket springs under it take over and the sinking stops there. That is a hybrid working properly, and among the five Silentnight Aloe Vera mattresses at Dreams it is the only one that has a go at it.
Couples will get the most out of it, and side sleepers of an average build are close behind. Avoid it if you wake up too warm as it is, because memory foam holds your heat whatever the cover is called. Avoid it too if you weigh eighteen stone or more and want a deeper spring unit to push against. I don't rate Silentnight as a rule, so it's awkward that the Clovelly is the one I'd buy out of the five. A medium over pocket springs is the first thing I put in front of somebody with no idea what they want.
A medium that owners agree really is medium
Nearly all the reviews here describe the Clovelly before this one, so the feel is all they can tell you. On the feel they agree, and in this range that's rare, because the label and the owners usually fall out. They call it a fair medium, neither hard nor soft. A few read it as firmer than they'd hoped, and one got back pain out of it. A couple of those say it's gone softer week by week, which is what Silentnight's own small print tells you to expect from foam.
Owners say a partner's turning doesn't reach them, which is the pocket springs doing their job, each one wrapped on its own. And one of them makes the point I'd make myself. You don't sink into this the way you sink into an all-foam bed, so turning over isn't a fight. Share a bed with somebody restless and that's the pairing worth paying for: no shove from their side, an easy turn on yours.
Good pocket springs, just not many of them
The springs are the best thing in this mattress and there still aren't enough of them. The name says 800 and the count is 682, and nothing tells you which size either number belongs to. Ask Dreams which figure applies to your size before you order. Ask how deep the memory foam layer is while you're on the phone. That layer is the one thing your extra money buys over the plain pocket-sprung mattress in the same range.
682 is a light count. A thousand under a double is already on the low side, and this sits a long way under that. What saves it is that they're pocket springs at all, and I'd take 682 pockets over an open coil at any count. Your weight goes straight down through a pocket spring instead of dragging its neighbours along with it. That's the difference you feel at three in the morning.
Check the Hadleigh before you pay
Dreams also sells a next-day mattress called the Silentnight Hadleigh, and on paper it's much the same thing: memory foam over the same 682 pocket springs, the same medium grade, a centimetre and a half shallower. Dreams moves its sale between the two, so this month's bargain can be the dearer one by the time you order. Compare both in your size on the day you buy and take the cheaper one. The Hadleigh comes in a double and a king only, so any other size makes the Clovelly your answer anyway.
Living with it is straightforward. At 26cm your usual fitted sheets will cope. Set a reminder on your phone: head to toe every week until the third month is out, then once a month, because the guarantee asks for it. Get the firmness wrong and Dreams' 100-Night Comfort Guarantee buys you a different mattress, not your money back, with a collection charge and one swap per order.
What to buy instead
Buy whichever of the Clovelly and the Hadleigh is cheaper in your size the week you order. If it's the memory foam you're unsure about, take the Silentnight Aloe Vera Castleton instead. Same 682 pocket springs, no foam over them, and the one I'd hand a hot sleeper. I wear socks in bed in January and still wake up too warm, so I know the type. A cooler room with a breathable duvet beats any cooling story about a cover.
