Simba’s Bank Holiday sale has up to 30% off mattresses and sleep essentials

Simba’s August Bank Holiday sale brings discounts across its entire range, with savings on mattresses, beds, pillows, duvets and bedding.

The biggest reductions are on mattresses. Shoppers can save up to 30% on the Hybrid Pro, Hybrid Luxe, Hybrid Ultra, Natural Escape and Natural Apex, including selected models with Simba’s new HeatRelease technology.

That “up to” matters, of course. Not every product gets the full 30% discount, so check the individual offer before mentally spending the saving on new pillows.

What’s included in the Simba Bank Holiday sale?

The discounts vary depending on what you’re buying:

• Up to 30% off mattresses

• Up to 25% off pillows and duvets

• 20% off beds

• 15% off mattress toppers

• 25% off mattress protectors and bedding

• 15% off slippers

It covers most of the bedroom, basically. Handy if your mattress has developed a suspicious dip, your pillows are flatter than pancakes or your duvet has been around long enough to qualify as a family heirloom.

Is the Simba Hybrid Pro worth buying in the sale?

The Hybrid Pro is the mattress we’d look at first. It’s currently Mumsnet’s best mattress overall and scored 86 out of 100 after six months of testing.

Our tester Natasha found it comfortable from the first night. It gave her excellent whole-body support, kept movement from her partner to a minimum and didn’t leave her overheating. It also helped with her lower-back niggles and held its shape throughout the test.

There are a few catches. It’s heavy, rotating it takes two people and the usual price is firmly in premium territory. A 30% discount makes that price considerably less painful. Read our full Simba Hybrid Pro mattress review for the good, the bad and the awkward-to-rotate.

Simba’s new HeatRelease mattresses are included too

Simba’s new HeatRelease mattresses will also be reduced by 30%. HeatRelease is available as an upgrade on the Hybrid Pro and Hybrid Luxe, while the Hybrid Ultra now comes with it as standard.

The technology uses heat-absorbing graphite strips to draw excess warmth away from the body. Simba says the strips begin working within 20 minutes and can help the sleeper stay up to 4.4°C cooler for as long as eight hours.

Those figures come from Simba’s own testing, and Mumsnet hasn’t tested the HeatRelease upgrade yet. We have tested the standard Hybrid Pro, which stayed comfortably temperature-neutral through warmer nights. It didn’t feel cold, but our tester didn’t wake up sweaty either.

The upgrade sounds promising for anyone who regularly overheats. It won’t turn a stuffy bedroom into an air-conditioned hotel suite, but anything that reduces the 3am search for the cool side of the bed has our attention.

When does the Simba Bank Holiday sale end?

The Simba sale runs from 22nd August 2026 until 31st August 2026. Discounts should appear automatically, but check the final price before paying. It’s also worth reading the offer terms if you’re buying several products or adding the HeatRelease upgrade.

Thirty per cent off something you didn’t need is still money spent. But if you’ve already decided on a Simba mattress, buying it in the sale makes far more sense than paying full price a week later IMO.
