Amazon Prime Day is here, which means thousands of items are on sale and you could theoretically save hundreds of dollars - assuming you enjoy the specific thrill of buying a mattress with the same urgency as a hostage negotiation. Yes, the lowest prices we typically see come during Amazon's summer sale, Black Friday, and Cyber Monday, but you can still save on WIRED-tested mattresses, sheets, and bedding. Act soon, because Prime Big Deal Days end tonight, and the deals will vanish like your commitment to comparison shopping.

Take the organic mattress, which we love. It strikes a balance between plushness and pressure relief, with a little bounce that makes it a solid pick for back sleepers who need extra support - a group of people who have suffered enough, frankly.

There's also a plush organic mattress featuring organic cotton and wool. The coils help reduce motion transfer, while the latex hybrid design suits anyone who likes the structured feel of coils with a plusher finish. Basically, it's for people who want to sleep on a cloud that's also been to architecture school.

For side sleepers - including pregnant people, though it works for anyone - there's an adjustable pillow that's highly customizable. The microbead filler hugs the body and supports pressure points, which is a fancy way of saying it won't betray you at 3 a.m.

Then there are the cooling sheets, which are among the best you can buy. Reviewer Nena Farrell was actually chilly at night while testing them, which is the highest praise a sheet can receive. With a discount of more than half off, you really can't beat this deal - unless you count the fact that you're reading about it on the final day.

And if you can't decide between an air purifier and a sunrise alarm clock, congratulations: this nifty 2-in-1 gadget means you don't have to. It's the perfect solution for people who want to wake up gently while also breathing slightly cleaner air.

Finally, for the white noise enthusiasts: this machine uses a real fan instead of fan sounds, bringing you a more natural experience. Because nothing says "natural" like a mechanical device simulating the womb while you doomscroll.
