Why should you choose this mattress?
The Simba Hybrid is designed to do a bit of everything well. Its microsprings compress individually, which means a partner's movement stays on their side of the bed, while the graphite infused Simbatex layer draws heat away: a pairing that suits couples and warm sleepers in particular. A nine zoned base adds firmer support where hips and shoulders need it. The 200 night trial and 10 year guarantee leave time to be sure.

Best suited for?
Couples
The microsprings compress individually, which means a partner's movement stays on their side of the bed.
Warm sleepers
The graphite-infused Simbatex layer is built to draw heat away as you sleep.
Back sleepers
A medium-firm feel over a nine-zone base gives firmer support where the hips and shoulders press in.
Combination sleepers
Springy, responsive microsprings make changing position easy.
Lighter weight sleepers, who Tom's Guide noted may find it a little too firm, and committed front sleepers, whose position the same reviewers found less well supported.

FAQ's
How does the 200 night trial work?
You get 200 nights from delivery to decide. If it is not right, Simba collects it free of charge and refunds you, and the trial applies however you pay, including on finance.
Is the Simba Hybrid good for hot sleepers?
It is built with them in mind: the Simbatex layer is infused with graphite and designed for more airflow than standard memory foam, and owner reviews regularly mention temperature regulation as a strength.
How firm is the Simba Hybrid?
Simba rates all its mattresses medium-firm, with a cradled feel in the top layers over a firmer base. Owner reviews broadly agree, with some noting it feels firmer than expected at first.
What is the guarantee, and is there any small print?
A 10 year guarantee covers manufacturing faults. One thing to check before you buy: Simba requires a mattress protector to be used for the guarantee to stay valid.
What sizes does it come in?
From a UK single up to a super king, with EU single, double and king sizes for European bed frames. Every size carries the same trial and guarantee.
