Amazon Prime Day mattress deals 2024: 11 best sales
1. Linenspa 10" Queen Size Memory Foam and Spring Hybrid Mattress: was $279 now $197 @ Amazon
The Linenspa 10" hybrid is one of the best cheap mattresses we've tested, offering decent pressure relief along the hips, shoulders and knees. We'd therefore recommend it mainly to side sleepers, though the stomach sleepers on our review panel also found it comfortable. It's also excellent value for money at $197 (was $279.99) for a queen in today's Prime Day deals. A twin size is down to $137 (was $179.99) and would be our top choice for growing kids and teens too.
2. Siena Memory Foam Mattress king size: was $499 now $424 @ Amazon
If you're shopping for the best Prime Day deal on the 10" Siena Memory Foam Mattress, the cheapest price for the king and Cal king sizes is on Amazon – both are reduced to $424, beating Black Friday pricing. No other sizes are on sale at Amazon so you'll need to head to the Siena Sleep sale for discounts on twin through queen sizes, with a queen Siena Memory Foam Mattress reduced to $399 at Siena Sleep. We recommend this mattress for back and stomach sleepers due to its firmer foam feel. It's breathable too, with excellent edge support and motion isolation for a lower price.
3. Zinus 10” King SIze Fiberglass–Free Hybrid Mattress: was $379 now $254 @ Amazon
This is one of the cheapest hybrid mattresses from a well-known brand in today’s Prime Day deals event. The medium firm Zinus 10” Hybrid Mattress uses CertiPUR-US memory foam and individually wrapped coils to relieve pressure across the body and provide good spinal support. It only supports a combined weight of up to 500lbs, so look at the Nectar Memory Foam Mattress (above) if you need an affordable mattress with a higher weight capacity. A king size Zinus 10” Hybrid Mattress is on sale for $254 (was $379) today, with the previously cheapest price being $321 – so the mattress is over $60 cheaper today.
4. Zinus 10" Green Tea Memory Foam Mattress: king size was $379 now $303.20 at Amazon
The Zinus Green Tea Memory Foam Mattress is a top-rated budget bed for side sleepers and stomach sleepers. It's up to 20% off in Amazon's Prime Day sale, with the biggest saving on the king size at $303 (was $379). You'll get a 10-year warranty and a 100-day returns period on this mattress, but there is no mattress trial so consider the Siena Memory Foam Mattress instead if you want a clear-cut sleep trial.
5. Sweetnight 12” full size Memory Foam Mattress: was $279 now $233 @ Amazon
If you’re looking for a taller memory foam mattress and ideally want a queen size for under $300, then this is the best Prime Day deal for you. Sweetnight makes good cheap mattresses for all sleeping positions and this 12” Memory Foam Mattress offers a lot of pressure relief and contouring comfort for a lower price. A queen size Sweetnight 12” Memory Foam Mattress is on sale for $259 (was $319) at Amazon today, beating the previous sale price of $282 last October. Memory foam does retain heat, so if you’re a very hot sleeper we’d recommend the Nectar mattress above or the Zinus Hybrid below instead.
6. Kin by Tuft & Needle queen size Mattress: was $699 now $489 @ Amazon
Tuft & Needle is one of the original and best mattresses in a box for all sleepers, and the 10” Kin by Tuft & Needle is exclusive to Amazon. It’s made using Adaptive foam that absorbs then dissipates excess heat through the night to maintain a neutral bed temperature so that you don’t overheat. It has very high user reviews scores on Amazon, averaging 4.7 out of 5, with sleepers rating it for pressure relief and motion isolation in particular. A queen size is on sale for $489.30 (was $699) in this year’s Prime Day deals, which exactly matches the previously best price we spotted during Black Friday last year. You’ll get a 100-night trial on the Kin by Tuft & Needle, with free returns and a 10-year warranty.
7. Casper Sleep Element Queen size Mattress: was $595 now $416 @ Amazon
If you’re shopping Amazon’s Prime Day event for the cheapest Casper mattress, you just found it – the Casper Element is on sale for $416 (was $595) in a queen size, offering fantastic value for a top-rated memory foam bed. The 10” Casper Element uses the brand’s own perforated AirScape foam to boost airflow, dissipating heat so that it doesn’t pool in the mattress and cause you to overheat while sleeping. It’s on the softer side of medium firm, so we’d recommend it more for all side sleepers, plus lighter to average weight stomach sleepers. Looking for a comfy dorm room mattress? A twin XL Casper Element is also on sale for $311 (was $445) today.
8. 12” Amazon Basics Gel Memory Foam Full Hybrid Mattress: was $318 now $254 @ Amazon
It wouldn’t be Prime Day without a deal on Amazon Basic mattresses, and this is a good one for people shopping for a cheap hybrid mattress ($308 for a queen) – either to use on their main bed or for a guest room upgrade. Gel memory foam delivers two benefits: it relieves pressure and helps to regulate in-bed temperature to prevent overheating. The use of individually-encased coils will also boost airflow, creating a cooler sleep surface overall. The downside with the 12” Amazon Basics Gel Memory Foam Hybrid Mattress is that it takes up to 72 hours to fully expand and you can’t sleep on it during that time. So if you need a new bed urgently, want a hybrid and for a bargain price, pick the Zinus 10” Hybrid instead as that inflates faster.
9. Tuft & Needle Original Mattress: was $645 now $515 @ Amazon
The Tuft & Needle Original mattress in a box has been around for years and is still a popular choice among people who want a no-frills, reliable memory foam bed with great pressure relief to reduce aches and pains during sleep. The Tuft & Needle Original is a little slimmer than the average bed-in-a-box at 9.5” versus 10”, yet impressively it can accommodate up to 500lbs in weight per sleeper (Amazon’s listing is incorrect at 350lbs total weight capacity). There are only two layers of foam inside the Tuft & Needle Original Mattress but they work hard: Adaptive foam infused with graphite and cooling gel to wick away heat, plus a 6.5” slab of support foam to prevent sinking. A queen size is reduced to $626 (was $895) in today’s Prime Day deals, which is over $100 cheaper than previous sale prices.
10. Leesa Legend Hybrid Mattress: was $1,599 now $1,235 @ Amazon
Amazon might be better known as the place to buy a budget bed, but that doesn't mean you can't find a luxury mattress for less this Prime Day. The Leesa Legend is a 12" tall hybrid that combines targeted pressure relief with tall springs to create a highly supportive mattress. The meticulous finish adds a premium touch to the Leesa Legend, and with a cover crafted from organic cotton, Merino wool, and recycled fibers, this mattress is also better for the environment. Our favorite Prime Day deal is on the king size, with a 15% saving knocking it from $1,959.95 to a competitive $1,665.96. This mattress does go on sale semi-regularly (both on Amazon and direct from Leesa) but the current price is among the best we've seen.
11. Lucid 8" Gel Memory Foam Mattress: was $183 now $136 @ Amazon
Sorry, kids, but the school term will be starting up again soon – and now is an excellent time to start shopping for your dorm room. The Lucid 8" Gel Memory Foam Mattress is an affordable and comfortable bed that will best suit side sleepers with a lighter build. The 8" build is a little short for adults, but for anyone who still has some growing to do, this is a top choice. The queen is 25% off this Prime Day, reducing it to just $226.99 (was $303.35). If you don't have much room in your dorm, you can also save on the full sizes. A 10" full is just $223.64 (was $276.14) in a crowd-pleasing medium feel, and the taller build should provide support for longer.
