The Slumberland Air Memory 2.0 Mattress is the first rung of the Air range at Bensons for Beds, sold in Medium and Firm. It's a plain hybrid, memory foam over full-height pocket springs, and you rotate it rather than flip it. I lay on the Medium in a Bensons store and liked it a lot.
Slumberland is a Bensons own brand made in its UK factory, and I rate it as well made and fair for the money. It suits side and back sleepers of average weight who want give at the shoulder and hip. Avoid this rung if you're heavy or you sleep on your front. My reservation comes from owners: it can arrive harder than the showroom one, and the new-mattress smell sometimes won't shift. Neither would stop me buying it.
How I tested it, and what I found
I tried the Medium on the shop floor at a Bensons store in November 2025, lying on my side, which is how I sleep. At about 61kg I found the medium tension just right: my hip and shoulder got enough give to settle in without discomfort. My shoulder felt completely at ease, and for a side sleeper that decides it.
It also felt notably cool to lie on, with a pleasant, steady temperature throughout. Overheating wakes me at night, so I notice. The edge was a nice surprise too: firm enough that I could lie near the side and never feel I might roll off.
That was the version sold before Slumberland re-developed the Air range in May 2026. On paper the springs went from 1050 to 1250, plus "new components" Bensons doesn't list. Lie on the current one if you can.
The Air 2.0 skips the mini springs, and I like it for that
1250 full-height pocket springs do the supporting, with no minis on top padding out the total. That's a modest count for a size Bensons doesn't name, so ask which before you compare figures. But every one is a support spring, and I'd take that over a big total of minis any day. Bensons calls them nested, packed in staggered rows with no gaps, and that geometry is all its extra-support claim rests on.
On top sit 40mm of Sensaform memory foam, Bensons' own name for it, zoned in seven areas. Zones only help if they line up with you, so if you're very tall or short, lie on it in your usual position first.
Bensons says air channels make the foam five times more breathable than standard memory foam, without saying what standard is. The quilt filling is mostly recycled plastic, so there's no wool helping with heat, and owners are split on temperature. It felt cool in the shop, and I'd still warn a hot sleeper that memory foam holds warmth under a duvet.
The delivered Air 2.0 can feel firmer than the shop one
Bensons pools its reviews, so many are about the earlier Air 2.0 or other items in the range, largely written before the re-development. I read them for themes. Most are happy with the comfort, and the commonest complaint is a familiar story: lovely in the shop, hard at home.
A few who ordered the Medium say it turned up far firmer, one saying it "feels like an extra firm". Fewer found it softer, but the handful written since the re-development include two Firm buyers who did, one calling it "like a soft sponge". Some of that is the first fortnight, which always lies to you, but a few still said it weeks later. Lie on the grade you're ordering, and read the comfort guarantee's conditions first, because it's a charged exchange that needs a protector.
Smell is the other complaint I take seriously. Several owners describe a chemical or musty smell lasting weeks despite airing. Air the room on arrival and ring Bensons if it lingers past a fortnight, because new-mattress smell normally goes in days.
The 29cm depth and the one-sided build need a little planning
Check your sheets: 29cm is close to the deepest mattress a standard fitted sheet will hold. A couple of owners found the top slippery enough that the sheet crept off the corners, the sort of bedtime faff I can do without.
It's no-turn, so you rotate it head to foot instead, which Bensons says to do regularly, and a few owners find it heavy to swing round. I'd rather turn a mattress, because two sleeping sides wear more slowly than one. Check the grade in your basket, because Medium and Firm share one listing and the selector loads on Firm.
What to buy instead
If you want firm because you lie on your back or front, or you're heavier, look at the Slumberland Air 3.0 Memory Mattress. It comes in Firm and Extra Firm, with 50mm of memory foam, 30cm of depth and 1300 mini springs above its 1250 full-height ones. Buy it for the firmer grades, not the minis. Average-weight side sleepers should stay on the 2.0 Medium and spend the difference on deep sheets.
