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.
The main draws here are depth and feel. At 32cm, the Apex is a substantial mattress, and that extra height usually translates to a more supportive, less 'close to the slats' feel than slimmer models. The medium firm rating makes it a sensible middle ground: enough give for side sleeping, enough push-back for backs and fronts. It carries a feed rating of 4.7 via Mattress Online, which is reassuring, and one retailer listing mentions a 10 Year Guarantee, though you should confirm guarantee terms with whichever retailer you buy from. £1,499 as a starting price is a lot. If the depth and hybrid build matter to you, it may justify itself.

Who's it NOT for?
Skip this one if you're on a tighter budget: the £1,499 starting price puts it out of reach for many. Lightweight sleepers who prefer a soft, cradling surface may find medium firm slightly too solid. And at 32cm deep, it may sit taller than some fitted sheets and bed frames comfortably allow, so measure first.

How firm is the Simba Natural Hybrid Apex?
It's listed as medium firm, which sits in the middle of the scale with a slight lean towards support. That tends to suit back and front sleepers well, and most side sleepers too, although lighter side sleepers may find it a little firm through the shoulders.
How deep is the Simba Natural Hybrid Apex mattress?
Simba's own site lists it at 32cm deep, which is taller than many mattresses. It's worth checking your fitted sheets, as standard ones can struggle with deeper mattresses.
What sizes does the Simba Natural Hybrid Apex come in?
Four UK sizes: Single, Double, King and Super King. Prices range from £1,499 to £2,699 depending on the size you choose.
Does the Simba Natural Hybrid Apex come with a guarantee?
A retailer listing shows a 10 Year Guarantee, but Simba's own product page doesn't currently state guarantee terms. Confirm the exact cover with the retailer you buy from before ordering, as terms can differ between sellers.
