Dormeo Octasmart Hybrid Mattress (Octaspring® + pocket springs) | Medium/Firm, 22cm high | UK Single 90 x 190

The essentials

If you’re shopping for a hybrid mattress, the Dormeo Octasmart is one of those designs that tries to cover two needs at once: supportive bounce from pocket springs, plus pressure relief and airflow from foam layers. On paper, it leans into a fairly active comfort feel thanks to honeycomb-shaped Octaspring® components that move in three dimensions, rather than staying rigid like some traditional foams.

It’s also positioned with a “middle” firmness in mind (Medium/Firm). That matters because hybrid mattresses often appeal to people who don’t want the extremes—either very soft and slow, or very firm and springy. If you’re after something you can use day-to-day without constantly second-guessing comfort, this is a sensible place to start.

Key features that actually shape comfort

What stands out most here is the combination of Octaspring® technology and pocket springs. The pocket springs are 8cm tall and sit to work alongside the Octasprings, with the stated goal of providing a more traditional, bouncier feel. That’s a helpful distinction: some hybrids feel more foam-led, but this one is explicitly trying to keep a responsive character.

Then there’s the honeycomb-style Octasprings designed to move three-dimensionally. The benefit they aim for is comfort that adapts better than plain foam—plus the ventilation claim. While you can’t verify “8x more breathability” without lab access, it does give you the right expectation for the design: better airflow is the focus, not just softness.

Finally, there’s a breathable Aerocell memory foam layer for gentle pressure relief. Memory foam is often loved for contouring, but not everyone likes the “stuck” feeling. Aerocell is presented here as breathable, so if heat build-up is your usual worry, it’s at least designed to address that concern.

What it’s like to sleep on (practical expectations)

A good way to think about the Octasmart is as a mattress that wants to feel supportive first, but still comfortable where you need it most. The pocket springs and Octaspring® elements are there to create responsiveness—so if you change position during the night, you should feel less resistance than on slower all-foam beds.

The three body zones are also worth noting. The product describes “individual Octasprings” arranged into customised body support zones to support correct spine alignment. In real life, that usually translates to a mattress that aims to better match your hips and shoulders rather than treating the whole surface the same.

Of course, no mattress is perfect for every body shape. If you prefer a very plush, sink-in feel, the Medium/Firm rating suggests this may feel more structured than you’d like.

Where it shines—and where it can fall short

This model looks particularly well-suited if you want: - A hybrid feel with more bounce than an all-foam mattress - Zoned support and spine-alignment intent - Pressure relief from a memory foam layer, but with ventilation as a priority

Where it may not be the best match is if your comfort preference is either very soft/forgiving (this is Medium/Firm, not a cushion-top) or if you specifically want maximum contouring. It’s built to respond and ventilate, that design direction isn’t always what people choose when they want deep “moulding”.

Also, bear in mind that “more breathability” claims don’t tell you everything about your room conditions. If your bedroom runs hot, you may still need good bedding choices and ventilation habits.

Buying verdict

It makes sense to buy the Dormeo Octasmart if you like the idea of a hybrid that’s designed for airflow and a responsive feel, while still offering some pressure relief. If you’re moving around in bed, or you want something that balances support with comfort rather than going all-in on softness, this is the kind of mattress that often appeals.

You may want to skip it if you’re chasing a very plush, slow, deeply conforming mattress, because the Medium/Firm direction and the spring-led bounce may feel too lively. And if you’re extremely sensitive to firmness differences, it’s worth being cautious—without a firmness trial, hybrids can land slightly firmer than you expect for your personal comfort.

Quick FAQ

Is the Dormeo Octasmart more foam-like or spring-like?

It’s designed to be spring-like in feel. The pocket springs are meant to add a more traditional, bouncier character, while the Aerocell layer brings gentle pressure relief.

Does it have zoned support?

Yes. It’s described as having three body zones using individual Octasprings arranged into customised body support areas.

What firmness should I expect?

The stated firmness is Medium/Firm. If you normally sleep on softer beds, it could feel more structured.

What’s the purpose of the Aerocell memory foam?

It’s included for gentle pressure relief and ventilation, so it’s not just there to add contouring.

Is the 22cm height likely to feel substantial?

At 22cm high, it should feel like a standard, properly “mattress-like” thickness rather than a thin topper style—though your exact feel will depend on your bedding and personal preference.
