The Dormeo range: memory foam, Octasprings and hybrids
Dormeo's memory-foam mattresses use Ecocell cores, while its Octaspring technology uses honeycomb foam springs. The Octasmart Premium Hybrid range sold by Bensons combines Octasprings with pocket springs. That's the range covered here: the plain Hybrid has no memory foam layer listed, the Plus adds a modest layer, and the Deluxe has deeper memory-foam cushioning. They aren't interchangeable feels.
A shop with branches everywhere, and you're choosing this mattress from the sofa. I value ten minutes lying on a showroom bed for crossing unsuitable feels off your list; here, you can leave your shoes on. The exchange terms are the only way back when you can't lie on it first, so read them.
Under the foam, two spring systems share the work
Bensons' listings describe a layered hybrid, with individually wrapped pocket springs working alongside Dormeo's own honeycomb spring, the Octaspring. Those Octasprings sit in five body zones and are said to move in three dimensions. Pocket springs under foam are the hybrid construction I'd pick by default. What I check is how thick the cushioning is, and these three are shallow for hybrids.
The listings put open-cell Aerocell foam over Ecocell and Fusion foam support layers. The plain Hybrid is 22cm deep, with no memory foam layer listed. The Plus is also 22cm, with 20mm of memory foam. The Deluxe reaches 24cm, with 40mm. You'll get more room to sink into the Deluxe's memory foam, while the Plus has a thinner cushioning layer. Those millimetres matter more to your feel than the length of the product name.
Dormeo's Octavent air system is described as helping airflow, with breathability and temperature claims in the listings. Foam holds heat, so hot sleepers should look beyond air channels when choosing: of these three, the Deluxe has the most memory foam to settle into. Compare memory foam mattresses with that warmth in mind.
Bensons' breathability and temperature claims wouldn't guide my choice either. A glass of wine has me awake on the hour with my head going, so I'd sooner fix what happens before bed than buy a promise about after it. All three arrive rolled in a box and are one-sided: rotate them regularly to spread wear, keeping the sleeping surface uppermost.
The Plus is my best Dormeo pick for most people
For most people, I'd order the Octasmart Premium Hybrid Plus ahead of its siblings: Bensons lists a medium feel, with a modest memory foam layer over the springs. One Plus owner, about a month in, says their sleep is gradually improving. Medium is also the safe swap when you're replacing a mattress and don't want a shock in either direction.
The Octasmart Premium Hybrid Deluxe is where I'd send lighter people and side sleepers who want more cushioning under their shoulder and hip. If you already sleep hot, skip it. The plain Octasmart Premium Hybrid takes you towards a medium-to-firm surface without a listed memory foam layer. Back and front sleepers who dislike sinking in should start there. Side sleepers should favour the other two.
Bensons requires a protector from the first night, a short minimum period of sleeping on the bed before an exchange, and charges apply.
