Simba September Sale 2026: What's Actually Worth Buying

Simba's autumn sale runs 22 September – 1 October, with up to 30% off. Here's what's genuinely worth your money, and what to skip

9/22/2026

Simba is running a sitewide sale this week, with mattresses cut by up to 30%, pillows up to 25% off, and 25% off duvets. Beds are discounted by 20%, and their other categories go up to 30% off too. Big sales like this can be more noise than signal, so we've dug through what's actually on offer and picked out the pieces worth your attention.

The one to actually consider: Hybrid Pro Mattress

Simba's Hybrid Pro is their flagship, and it's the one worth the closest look. It pairs two layers of their Aerocoil® microsprings with Simbatex® foam for cushioning, and the springs are also designed to reduce motion transfer if you sleep with a partner. On top sits a "cool-touch" Stratos® cover, a breathable wool layer, and graphite-infused foam aimed at hot sleepers. The cover zips off and is machine-washable, which is a genuinely practical touch ,most mattress covers aren't.

It's backed by a 200-night trial and a 10-year guarantee, and it now comes in a HeatRelease™ version (as an optional upgrade), which is also included in the 30% discount.

Why it's worth it: cooling technology plus a washable cover is a real point of difference against most mattress brands, who tend to offer one or the other, not both.

The honest downside: the Hybrid Pro is a medium-firm mattress, which won't suit everyone, side sleepers or anyone who prefers a plush, sink-in feel may find it firmer than expected. Worth checking Simba's firmness guide before buying, or leaning on the trial period if you're unsure.

Worth watching: the new HeatRelease™ mattresses

Simba has just launched HeatRelease™ technology, and all three versions are included in the sale:

  • Hybrid Pro with HeatRelease™ – 30% off

  • Hybrid Luxe with HeatRelease™ – 30% off

  • Hybrid Ultra with HeatRelease™ – 30% off (comes as standard on the Ultra, rather than an optional upgrade)

If overheating at night is your main complaint with your current mattress, this is the newest tech Simba has, and getting it at full sale discount from launch is a reasonable time to try it rather than waiting.

Worth bundling if you're already buying a mattress

Pillows (up to 25% off) and duvets (25% off) are a sensible add-on if you're replacing a mattress anyway, since matching a new mattress with an old, flattened pillow undercuts a lot of the benefit. On their own, they're a smaller saving and less worth rushing for.

Bottom line

If you've been putting off a mattress upgrade, the Hybrid Pro is the standout pick in this sale, proven design, a genuinely useful washable cover, and a 200 night trial that removes most of the risk. The new HeatRelease™ range is worth a look specifically if heat is what's been ruining your sleep. Everything else in the sale is fine to add to a mattress order, but not worth shopping for on its own.
