A box a bit over a metre long turns up, you cut the plastic off, and 27cm of plain medium mattress unrolls onto your frame. Four to six hours later you can sleep on it, and by the third day the creases have gone and it's up to full height. That is the Lime's whole appeal, and it sits one rung below the softest bed in the new Hyde & Sleep Serene range, the softest of the three Dreams will send you rolled.
Buy it if you already know a plain medium is the feel you want and you'd rather not wait months to get one. Heavier sleepers should look elsewhere. Ask Dreams to point at the memory foam before you order, if that's what you're buying it for: both comfort layers in here are Serene foam, Hyde & Sleep's own quick-recovery stuff, and the advertised memory foam isn't in the build. Cautious is where I land on it. The grade is right and the foam over the springs is generous for this rung, and I still find this brand mostly too firm and a bit dear for what's inside. A Medium answers the first half of that complaint and not the second.
The foam is the mattress and the springs are one thin sheet
Hybrid is doing a lot of work in that name. Under the two Serene foam layers sits one thin mat of micro springs, no full-height spring unit anywhere in it, and no published count for the mat. Micro springs are spring-count padding to my mind, and here there isn't even a number to be rude about. They soften the surface and they do that well enough. What they can't do is hold a hip up the way a proper pocket unit holds one, which is the whole reason I'd steer a heavier body away from this one.
Don't read 27cm as 27cm of comfort, either. No thickness is published for either Serene layer, and a deep layer of plain base foam sits under the springs, eating into the 27cm. The second layer gets three support zones, which works nicely when your shoulders and hips land where the factory expects them to and does nothing for you when they don't. Steer clear if you are over eighteen stone or thereabouts. With neither a count nor a wire gauge published, there's nothing on paper that tells you the support will last you.
The roll is the reason to buy this one and not its flat twin
Buy the rolled version rather than the flat one. It's the same mattress at the same money, and the flat one keeps you waiting months instead of weeks. The roll is about 110cm long and a bit over 42cm square, which decides whether a mattress goes up a staircase or jams on the turn. The stairs at my old place were narrow enough that I'd take the box every time now. It weighs the better part of 33kg, mind, so get a second person in for the day it arrives.
Check your fitted sheets before the delivery date. At 27cm it's under the depth where sheets turn into a wrestling match, though a shallow pocket will still pull tight at the corners. The zipped cover doesn't come off and isn't for washing, so a spill means a damp cloth and quick work.
Read the small print on the 100-Night Comfort Guarantee before you pay: it gets you a swap and your money stays put, there's a charge to collect the one you send back, and a protector has to be on the mattress from the first night.
What to buy instead
Put a bit more money into the Hyde & Sleep Deluxe Ice. Same medium grade, 32cm against 27cm, memory foam pods in the stack where you'd expect to find them, and an edge claim this new range never makes. It'll sleep warmer, the way memory foam always does, so anyone who wakes up too hot should stay where they are.
Going the other way, the Hyde & Sleep Blueberry Rolled is the save: the same Serene foam over the same spring sheet, one grade firmer, 3cm shallower and less money. If a plain medium is the feel you came for, don't save it there. Firmer is the thing you were trying to avoid.
