Simba discount codes & offers

Simba is a Bristol mattress company built around the Aerocoil, a small titanium-alloy spring that it layers into foam in its Hybrid mattresses and into wool in its Natural Hybrid line.
Companies House lists Simba Sleep Limited as incorporated on 27 July 2015, with mattress manufacture as its business.
Simba became a certified B Corporation in 2023 with a score of 97.5, where 80 is the pass mark, as Furniture News reported at the time.
Its range splits into the foam-and-spring Hybrid line and the foam-free Natural Hybrid line of wool and springs, which Simba describes as “crafted and tufted in the UK”.

Simba mattresses by depth and spring count

Trial and guarantee

Simba’s 200-night trial applies to mattresses, beds and toppers, with free collection and a refund to the original payment method.
The guarantee page is less generous than the headline suggests.
Bought direct, a mattress is covered for 10 years; bought from a retailer such as Argos or John Lewis, it is covered for five unless you register it with Simba.
Cover also depends on using a suitable base and a protector, and on rotating the mattress monthly for the first three months and quarterly after that.

Choosing Simba

Simba suits sleepers who want a springy hybrid and a wide choice of depths.
The Hybrid Pro is third in best mattresses 2026 and second in our double and king size comparisons.
Among toppers, the Hybrid Essential Topper is second in double mattress toppers and the Hybrid Topper is third in our main topper ranking, while three Simba protectors take second to fourth place in mattress protectors.
It is a poorer match on a tight budget, since the four deepest models start above £1,000, or if you would rather not keep to a rotation schedule to protect the guarantee.
