Deal hunters, it’s time to pay attention because it’s the final day of Amazon Prime Day. The sale delivers the crème de la crème of beauty bargains, home appliance savings, new tech discounts and much more, year after year.
True to form, we’ve brought you the best offers on products that have the IndyBest seal of approval, including stellar savings on mattresses that we’ve tried, tested and loved. We’ve spotted mattresses from premium brands such as Emma, Simba and Dormeo slashed in price during previous Prime Day sales, and 2024 is no different.
We’re also seeing some brilliant discounts across the likes of coffee machines, laptops, TVs and more, so it’s certainly a sale to stick around for. However, these deals are only available to Amazon Prime subscribers, so, you’ll need to sign up for a Prime account (more on that later) if you want to take advantage of the offers.

As for this mattress, it sounds similarly impressive. While we’re yet to test it, the brand says that it’s been designed for those who run hot at night, as it claims to offer 30 times the air flow of a standard memory foam mattress. Owing to the support and cushioning, Simba states it should provide relief to your pressure points.

Upon trying out the mattress, our tester said: “Sinkage is perfect, as is the balance of support and cloud-like cushioning. Its medium firmness is suited to those who sleep on their side, front or back, while its breathability makes the mattress a stellar option for those who tend to get hot during the night.” Already a great mid-range price, this mattress is now 30 per cent off.

Our tester added: “Whichever side your child is using, the mattress is ultra gentle – it’s been treated to be hypoallergenic and has a fibre core to help keep air flowing through the mattress, to prevent overheating.”
Nectar king mattress: Was £519.60, now £436.99, Amazon.co.uk
Comfort and support are among the top things we look for when testing mattresses, and our reviewer was blown away by this model’s capabilities on both fronts. "We were pleasantly surprised to find that when we lay down, it actually felt more like a hybrid (a foam mattress that also has pocket springs) than a pure foam mattress," they said. High praise, considering hybrids are considered more comfortable and much more expensive. They also found this mattress ticked all the boxes for breathability, hypoallergenic qualities, temperature control and, of course, the price tag.
Panda hybrid memory foam bamboo mattress: Was £1,550, now £1,377.99, Amazon.co.uk
This vegan, naturally hypoallergenic mattress was named the best for back sleepers in our tried and tested review. Courtesy of Amazon, you can now save a modest 11 per cent on the hybrid design – every little helps when it comes to buying investment items such as mattresses. During testing, our reviewer found this model to be on the firmer side of medium, and noticed a “very slight sinking-in feeling, with a subtle bounce, owing to a layer of springs”. With £80 off the price tag, you’ll have a little extra cash for some new bedding, too.

Even better, you can currently invest in the single mattress while it has 16 per cent off at Amazon. In their review, our tester noted they “benefitted from the cooling technology during balmy nights”, while, in terms of comfort and support, the design improved our reviewer’s pressure points within weeks.

Jay-Be natural fresh bamboo e-pocket children’s mattress: Was £300, now £249.99, Amazon.co.uk

It has more than £50 off for Amazon Prime and our tester found that it doesn’t feel like “it’s going to sag after six months of use, and [they] felt happy to have [their] child sleeping soundly on it”. They added that, while their little one runs hot, they didn’t sweat through the night on this mattress even with a higher tog duvet.

Reduced by 37 per cent, this medium-firm double mattress features multiple layers of foam and a pocketed coil support system that is designed to conform to your body’s every curve. This should evenly distribute pressure on your shoulders, back, spine, and hips for a comfortable night’s sleep. Individually pocketed springs absorb shock, as well as rebound and eliminate motion transfer, which could be a blessing to anyone whose partner tosses and turns in the night.
Coleman extra durable raised double air bed: Was £89.99, now £62.49, Amazon.co.uk
Just like Amazon, we are covering all bases with this sale, and so we had to include an option for the adventurers out there. One of our favourite air mattresses, which is perfect for summer camping trips, is now 30 per cent off. Our tester said: “It offers one or two campers or overnight guests excellent padding when fully inflated, and if you’re sharing, you’ll have plenty of space.” And at that price, they promise “it won’t dissapoint”.
Do you have to be a Prime member to access Prime Day deals?
The short answer is yes. Amazon Prime Day deals will be reserved for those who have a Prime Day subscription, but signing up couldn’t be easier. There’s also a 30-day-free Prime Day trial, but be wary that, once this lapses, there’s a monthly fee of £8.99 or £95 for a year. You can, of course, cancel at any time, though.
