Features CertiPUR® certified foams, ensuring no harmful chemicals.
Assessed from Simba's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This is a sensible pick if you sleep warm or share a bed. The Simbatex foam and wool layer are designed for airflow, and across verified owner reviews temperature regulation and minimal motion transfer come up consistently. The double layer of Aerocoil microsprings targets pressure points, which means side sleepers should feel relief at the shoulders and hips without sinking through to the base. Yes, it's a fair outlay at £899 upwards, but the 200-night trial and free returns take most of the risk out of the decision. The SupportCore sprung base gives firm edge-to-edge support with no roll-off, useful if you sit on the edge of the bed or sleep near it.

Who's it NOT for?
If you prefer a distinctly soft or a very firm mattress, the medium-firm feel here may not suit. Traditionalists after an all-natural build should look elsewhere, as this uses synthetic foams alongside the wool. And if your budget is tight, £899 upwards is a serious spend.

How firm is the simba hybrid pro?
Simba describes the Hybrid Pro as medium-firm. That suits most sleepers, particularly back and combination sleepers, although very lightweight side sleepers may find it slightly firmer than ideal.
Does the simba hybrid pro come with a trial?
Yes. Simba offers a 200-night trial with free returns during the trial period, so you can test it at home across the seasons before committing.
Is the simba hybrid pro good for hot sleepers?
It's built with heat in mind. The cover uses Stratos technology to prevent heat build-up, a wool layer adds breathability, and optional HeatRelease graphite strips can keep you up to 4.4°C cooler.
How many springs does the simba hybrid pro have?
It has 4,800 springs in total, combining two layers of Aerocoil titanium alloy microsprings with a SupportCore base of up to 1,000 pocketed, tempered steel barrel springs.
How long is the simba hybrid pro warranty?
Simba provides a 10-year guarantee on the Hybrid Pro, and retailer listings show a 10-year warranty as well. Free UK delivery is standard, with seven-day-a-week delivery if you pick a date at checkout.
