The iGel NanoTech 3000i is the iGel I'd send most people to, and the reason is the top: there's no plush top on this one. You get pocket springs under a 40mm layer of iGel's graphene foam, a quilted cover and a 31cm profile, sold in Soft, Medium and Firm. I really like iGel as a brand. Buy this if you're an average-weight back or side sleeper who wants springs with a cushioned face. If you're hoping the cooling claim will fix your hot nights, don't buy it for that reason alone.
The plush top has gone, and that's the upgrade
This listing used to carry the iGel Advance 3000 Plush Top, and Bensons now sells the NanoTech 3000i in its place. The plushtop has moved up the range: the 3500i and above carry it in their names, which leaves the 3000i as the biggest NanoTech without one. I steer people away from plush and pillow tops because the soft top softens further, dips where you lie, and you can't flip the mattress to give it a rest. Losing it makes this the better bed of the two.
The cooling foam changed as well. The old model used an earlier iGel foam, and the 3000i has the newer NanoTech layer, which iGel says moves heat twelve times faster than standard memory foam. Treat that figure as iGel's own and judge the layer as foam with a mild cooling benefit.
Count the springs before you count on them
Three thousand sounds like a lot, and some of it is padding. Bensons calls them dual layer pocket springs, a mix of mini springs and full-height ones, and the listing doesn't say how many of each. The full-height springs hold you up, while minis mostly add a springy top and a bigger number for the label. So before you pay for the 3000i over the 2050i a rung down, ask Bensons how many of its springs are full height.
It's developed with the British Chiropractic Association and carries GenM's MTick menopause-friendly mark. I respect a maker that puts a real partnership behind a bed, and I still judge it on the layers. At 31cm it's deep, so measure your fitted sheets before you order and expect a taller climb into bed. It's no-turn, rotated as the care guide says, and Bensons advises against electric blankets on iGel mattresses, which matters if you rely on one in winter.
Cooling: some owners feel it, plenty don't
I'm on gel foam's side, because it does seem to help, but the owners split. Some say they stay cool at night for the first time in years. Others say it sleeps as warm as any mattress they've had, and one now sleeps with a fan in the room. I'm not giving up my weighted blanket for anyone, so I'd love this to be the fix. If you run very hot, a spring mattress with wool and cotton fillings is the surer bet.
Firmer at home than in the showroom
The complaint to plan around is firmness. Owners keep saying the mattress that arrived felt nothing like the showroom sample. "Firmer than I expected" is the mild version, and you hear it from owners of the Medium and the Soft. A showroom bed has been softened by every passing shopper, and yours arrives new. Lie on it for a full ten minutes in your usual position, and if you're torn between two grades, take the softer.
A smell that hangs around is the other thing I take seriously. Most owners say it cleared in a few days, but a few couldn't use the bed for a week or more. Read Bensons' comfort guarantee before you buy, too: it's an exchange with a charge and a redelivery fee, and you must have used a protector (Bensons' terms, checked October 2026).
Avoid it if you can't rotate a heavy 31cm mattress on your own, if you sleep under an electric blanket, or if you're light, sleep alone and want the Medium to feel soft from the first night. One small owner who slept alone found it never softened enough.
What to buy instead
If the 3000i sounds right but too firm, buy it in Soft before you look at a plushtop model higher up. If you sleep hot, look at pocket springs with natural fillings. If the price is the sticking point, the 2050i keeps the same NanoTech layer a rung down. Would I buy it? Yes, in Soft or Medium, once I'd asked about the spring split and read the exchange terms.
