There are two kinds of people: those who treat sleep like a non-negotiable and those who treat it like a hobby. If you’re reading a mattress review, you already know which camp you’re in—and Simba is aiming squarely at anyone fed up of waking up stiff, sweaty, or yanked awake by a partner who treats the duvet like an opponent in the final round at the Rugby World Cup.
The headline number is blunt. The Simba Hybrid Mattress in a double comes in at £799, which is enough money to make you briefly consider sleeping upright like a well-behaved horse. But Simba also knows the mental hurdle, so it puts the comfort blanket around the purchase: 200-night trial, 10-year guarantee, free next-day delivery, old mattress removal, and finance “from £21.12 per month over 48 months.” In short: premium price, but with every possible nudge to stop you flinching at checkout.
What you’re really buying: hybrid, done the modern way
A hybrid mattress is supposed to be a peace treaty between foam and springs. Foam can feel wonderfully cradling… until it turns your bed into a slow-cooker. Springs can keep you cooler and feel supportive… until they start bouncing you around like you’ve booked a budget trampoline.
Simba’s calling card is how it positions its Aerocoil® microsprings: closer to the top of the mattress, where you actually feel the engineering doing the work, rather than hiding the clever bits deep down where only your bed base can applaud. In a double, Simba says you get up to 1,900 microsprings in that layer—designed to compress independently for more targeted support and improved airflow.
If you like your specs practical rather than poetic, that “independent compression” detail matters. It’s the difference between a mattress that reacts to you and one that reacts to gravity and regret.
Medium-firm: the mattress equivalent of “just right”
Simba labels the feel as medium-firm, and that choice is as strategic as it is sensible. Most people flirt with extremes—too soft and you sink, too firm and you feel like you’re sleeping on a well-polished pavement slab—then end up right back in the middle.
Simba also builds around a nine-zoned support system, aimed at keeping you aligned, especially around hips and shoulders. The promise (and the point) is a top that feels “hugged” with firmer structure underneath—comfort first, support second, and zoning to stop your hips staging a solo expedition at 3 am.
This is where Simba’s design reads as coherent rather than flashy: if you’re going to claim “supportive,” you need a build that actually behaves like it when real bodies, real heat, and real tossing-and-turning get involved.
Cooling: where mattresses win or lose the room
If you’re a hot sleeper, you don’t need a lecture—you need relief. Overheating turns “eight hours in bed” into “eight hours of negotiations.” Simba’s answer is Simbatex® foam, described as having over 5x more airflow than memory foam, and it’s graphite-infused to help move warmth away from the body.
This is the battleground for modern mattresses: “comfort” that doesn’t punish you later. Simba is clearly chasing that memory-foam-style cushioning without the heat hangover. Add the breathable cover plus a zip-off, machine-washable top section, and you’ve got a setup designed for lived-in bedrooms, not showroom lighting.
Motion transfer: the feature couples quietly pay for
One of the most practical claims Simba makes is that the Aerocoil microsprings respond separately to movement—so your partner’s toss-and-turns stay on their side. For couples, that’s not an indulgence; it’s basic night-time diplomacy.
In plain terms: fewer ripple effects, fewer surprise wake-ups, and fewer moments where you stare at the ceiling reconsidering every life choice that led you to share a bed with a human hurricane.
Specs people actually use when comparing tabs at midnight
Here’s the Simba Hybrid® Mattress (Double) stripped back to what matters:
- Price: £799 (Double)
- Feel: Medium-firm
- Construction: 5 layers, 25cm depth
- Support: 9 support zones
- Comfort layer: Aerocoil® microsprings (up to 1,900)
- Cooling layer: graphite-infused Simbatex® foam
- Cover: breathable, zip-off, washable top
- Trial & aftercare: 200-night trial, 10-year guarantee

- Extras: complimentary Hybrid™ Pillow(s) “worth £218”
- Add-on: mattress protector (+£129)
- Sustainability signals: B Corp, CertiPUR® foam, some recycled materials, UK-made, recycling/refurb options
That checklist is the real reason Simba stays in the conversation: it’s not one shiny feature, it’s a stack of sensible decisions aimed at the everyday problems people actually complain about.
The sustainability angle: sensible, not preachy
Simba positions itself as a “force for good” with B Corp status, CertiPUR® foam, and efforts to use recycled materials where possible. It also leans into being made in the UK by experienced craftspeople, which doubles as a quality cue and a supply-chain reassurance.
It’s not claiming to save the planet with your duvet—good. But it does give modern buyers enough confidence that they’re not paying premium money for something disposable.
Verdict: who the Simba Hybrid Mattress suits best
The Simba Hybrid® is built for people who want three things at once: support, comfort, and a bed that doesn’t behave like a radiator. If you’re shopping because you wake up achy, sleep hot, or share a bed with someone who moves like they’re escaping a haunted house, the design choices here are rational—not gimmicky.
The honest truth is that comfort is personal. But the 200-night trial makes this less of a blind leap, and the spec sheet—especially that up-to-1,900 microspring comfort layer and the graphite-infused foam—has enough substance to justify a shortlist place.
If you’re going to spend £799 on a double mattress, you want it to change your sleep, not just your bank balance. This Simba is built to do exactly that—provided medium-firm is your happy place and you value cooler, steadier nights over sink-in softness.
