In celebration of World Sleep Day (yes, that really is a thing) on March 14, Simba is discounting mattresses, bedding and even beds by up to 20%. The flash sale, which is only running for one week, has discounted mattresses by 20%, bedding including pillows and duvets by 15% and select beds by 15%. But the limited-time offer won’t be around for long, with the sale ending on Sunday, March 16, 2025.
Upgrading your mattress, in particular, can be costly – so when a sale like this comes around, it’s worth thinking about that purchase you might be putting off. According to the National Sleep Foundation, you should consider doing this around every eight years – though many of us probably leave it slightly longer than that. And given you spend around a third of your life in bed (that is if you manage to get your full eight hours a night), it’s an investment worth thinking about.
I’ve done some digging and found the most significant savings on the website. Yes, it’s a splurge, but it might just be worth it—and it’s certainly not as big of a spend as if the mattress wasn’t on sale.
As part of the deal, the Superking Hybrid Ultra Mattress, which usually retails for £3,299, is discounted to £2,573.22. That’s a saving of £726. It’s a mattress that promises a supportive night’s sleep – I should know because I’ve been sleeping on one of Simba’s Hybrid Ultra Mattresses for almost two years. When I reviewed the Simba mattress, I gave it a top score of five stars.
Along with mattress and bedding discounts, the Simba sale has slashed the price of bedtime bundles. These include mattress bundles, which come complete with duvet and pillows, bed bundles, which include frames and mattresses, and complete sets, which include a bed frame, mattress, duvet and pillows. When buying a bundle, you’ll save even more money than if you purchased each item separately – so it’s worth considering if you’re revamping your entire sleep set-up.
I’ve rounded up some top discounts from the Simba sale below.
