Simba's Hybrid Pro is the choice for back-pain sufferers who run hot or carry more weight. At around 28cm deep it layers thousands of titanium Aerocoil micro-springs (Simba cites around 4,800) over a supportive base, topped with graphite-infused Simbatex foam and a natural wool layer that reviewers single out for temperature regulation. The result is a medium-firm feel with more cushioning than the OTTY, which reviewers report distributes weight well for heavier back and stomach sleepers. It comes with a 200-night trial, among the longest here. The trade-off is price and value: an indicative double sits around £899 even discounted, notably more than the OTTY, and the plush multi-layer feel gives up a little of the firm, direct support some bad backs prefer. Choose it over the Nectar below for its cooler sleep and springier support; choose the OTTY instead if value and firmness matter more than cooling.
The good & the bad
Pros
- Natural wool and graphite Simbatex top are rated highly by reviewers for cool sleep
- Layered micro-springs distribute weight well for heavier sleepers
- Long 200-night trial to judge back comfort over time
Cons
- More expensive than the OTTY and Emma for similar support
- Plush, cushioned feel is less firm than some bad backs want
