Simba Kingsize Hybrid Mattress Review: Is It Worth It? | Northern Life
by Karen Shaw
When the Simba Kingsize Hybrid Mattress arrived, it didn’t immediately fill me with confidence. The box was so compact I wondered if a second delivery was on the way. I even held off tossing my old mattress, just in case. But once opened and released from its vacuum seal, the Simba Hybrid expanded over the recommended six hours into a full, substantial kingsize mattress — far more impressive than its modest arrival suggested.
This was my first real indication that Simba knows precisely what it’s doing.
What Is the Simba Hybrid Mattress?

The Simba Hybrid Kingsize Mattress is designed to offer the best of both worlds — the comfort of foam and the structure of springs. But unlike many hybrids on the market, Simba’s version feels engineered with precision rather than simply layered together.
Key Features:
- Aerocoil® titanium alloy microsprings
- Simbatex® graphite-infused cooling foam
- Nine-zoned support base
- 25cm depth
- Removable, washable cover
- Medium-firm feel
These aren’t just technical details; each element plays a role in how the mattress performs night after night.
Design & Construction: A Smarter Hybrid
Right at the top of the mattress are Simba’s Aerocoil® microsprings — up to 1,900 of them in a single layer. They respond individually to movement, offering precise support and minimising motion transfer. If you share a bed, this is a major advantage.
Underneath sits Simbatex® cooling foam, infused with graphite to pull heat away from the body. Unlike traditional memory foam, which can trap heat, this layer maintains airflow while still gently contouring to your shape.
Beneath it all, the nine-zoned base provides targeted support to the shoulders, hips and lumbar region. It aligns the body without the rigidity found in older-style spring mattresses.
Cooling Performance: Does the Simba Mattress Sleep Cool?
Temperature regulation is one of Simba’s most significant claims, and frankly, it delivers. The graphite-infused Simbatex® layer and the airflow generated by the Aerocoil® springs work together to keep the mattress consistently cool.
Across multiple nights, I didn’t overheat once — no duvet kicking, no tossing and turning, no ventilation leg hanging off the side. The temperature remained steady and comfortable, making it one of the best hybrid mattresses for hot sleepers.

Comfort & Support: How Does It Feel to Sleep On?
The Simba Hybrid offers a medium-firm feel, which will suit a wide range of sleepers. It has enough softness on top to feel inviting, but plenty of support underneath to keep your spine aligned.
What stood out:
- I settled into a comfortable position quickly
- No sinking sensation — just balanced, stable comfort
- Excellent pressure relief on shoulders and hips
- Minimal partner disturbance
After several nights, I woke up free of the usual shoulder and lower-back tension — a sign that the zoned base and microspring system are doing exactly what they claim.
If you’re searching for a mattress that supports without smothering, this one sits in that sweet spot.
Practical Features: Everyday Usability
The Simba Hybrid includes several thoughtful touches that make it appealing for long-term use:
- Zip-off, washable cover → ideal for keeping things fresh
- 25cm depth → gives a premium feel and suits most bed frames
- Excellent durability → the materials feel built to last
- 200-night home trial → try it across seasons
- 10-year guarantee → long-term peace of mind
It’s the kind of mattress built to stay comfortable and supportive for years, not months.
Is the Simba Kingsize Hybrid Mattress Worth Buying?
Once settled on the bed, the Simba Kingsize Hybrid quickly proves itself to be a well-crafted, thoughtfully engineered mattress. It’s cool, supportive, and quietly luxurious without ever feeling showy. The combination of Aerocoil® microsprings, cooling foam and zoned support works together with impressive consistency, delivering a genuinely restorative night’s sleep.
With comfort, stability, and innovative design on its side, it’s a mattress that instantly feels like the right decision—and stays that way.
