I'm a sleep writer and sales hunter – these are the best early Amazon Prime Day bedding deals

The Nectar Memory Foam Mattress is one of our top contenders for the title of 'best mattress', and it's currently listed for $200 less than its RRP. When our expert tester, Casey, sampled the Nectar Memory Foam Mattress, she found it significantly eased the aches and pains from her fibromyalgia – that'll be the pressure-relieving properties of memory foam.

The DreamCloud Luxury Hybrid Mattress marries the contouring comfort of memory foam with the airflow and support of an innerspring. Our expert tester, Camryn, particularly approves the edge support, which makes it so much easier to get into and out of bed. Best of all, for a self-described 'luxury mattress', it's not even that expensive, and you can bag it for half the price when you shop the Amazon Prime Big Deal Days sales.

This deal has gone up and down over the past few days, but now it's settled around the $300 mark. Ordinarily, that would raise alarm bells for me, but I know the Zinus Cooling Green Tea Mattress − our expert tester, Camryn, won't stop talking about it. You get all the plush comfort of memory foam with the airflow of an innerspring, thanks to a cooling gel infusion which dissipates heat and wicks moisture.

The best affordable bed sheets just got even more affordable. Made from microfiber and double-brushed for softness, these sheets are machine-washable and dryer-safe for quick and convenient cleaning. The Mellanni Queen Sheet Set gets a great write-up on Amazon, with more than 250,000 five-star reviews from verified customers.

Our expert tester, Lucy, can't get enough of this cotton percale sheet set. Breathable yet durable, the Martha Stewart 100% Cotton Sheet Set is up to the challenge of hot summer nights and and countless laundry cycles. Just bear in mind that the set only comes in sizes Twin, Full, Queen, and King.

If you're a hot sleeper, like I am, then you need a set of the best cooling sheets to keep the night sweats at bay. The Bedsure Queen Sheet Set is made from rayon, derived from bamboo, which is naturally thermoregulating and antimicrobial to bust the bacteria that breeds in warm, damp environments, such as beds.

This memory foam pillow is made to mold to the shape of your head, neck, and shoulders, taking the pressure off your joints for the feeling of weightless sleep. Unlike your average memory foam, which quickly incurs indents and impressions, TEMPUR material is designed to spring back into shape once your weight is removed.

This down alternative pillow is suitable for hot sleepers, vegan shoppers, and buyers on a budget. The whole thing is wrapped in cooling cotton percale to boost breathability, and the outer cover is machine-washable for easy cleaning. The only downside is that it lacks a little of the natural loft you get from real down.

If you suffer from night sweats or hot flashes, or you simply tend to run a little warm, then this is the best pillow to keep you cool. This pillow features two layers of TEMPUR-breeze cooling gel, one on either side of the pillow, to dissipate heat and wick moisture, whichever side you sleep.

Real down makes the best bedspreads. Each feather and fluffy cluster in the Wellos Goose Down Comforter meets the Responsible Down Standard, which indicates ethical practice at every stage from farm to factory. That's good news for eco-conscious shoppers and anybody who wants a nice, fluffy comforter.

This down alternative duvet insert might be a better option for vegan shoppers, though it lacks a little of the loft you get from real down. The Bedsure Comforter comes in every size from Twin to California King, with oversized Queen and King options to create a dramatic drape.

This is the sort of comforter that would go great in a college dorm or starter apartment. It's machine-washable, highly affordable, and comes in a range of shades to complement any color palette. Granted, it isn't the best duvet insert out there, but you won't find much better for this price.

I think this is the best mattress topper on the market, but I often hesitate to suggest it because it's so expensive. Now, with a 40% discount for Amazon Prime Big Deal Days, I feel a lot more confident. The motion isolation is unmatched, the edge support is excellent, and the whole thing is secured with no-slip corner straps for a snug fit.

This is just the thing to soften up a firm, inflexible bed for a fraction of the price of buying a new mattress. The Sleep Innovations Mattress Topper is filled with gel memory foam to dissipate heat and wick moisture. Still, if you're a seriously hot sleeper, I suggest you cover your topper with one of the best cooling mattress protectors.

The SameBed Mattress Topper is what you'd get if a mattress pad and a mattress protector had a baby. It comes with a stretchable knitted skirt for a snug, secure fit, all around the edges, and a box-quilted design to keep the microfiber fill firmly in place. That means no lumps and no bumps in your bed.

The SafeRest Mattress Protector boasts a 4.6 average star rating from more than 270,000 verified customer reviews. One particular review caught my attention: the customer claims to use this mattress protector in the vacation rental he operates. Whatever spills and stains his guests bring into his bed, the SafeRest Mattress Protector manages to keep the mattress itself clean and dry.

This six-sided mattress protector is made to safeguard against spills and stains from every angle. Covered with cotton terry cloth, the SureGuard Mattress Encasement is soft and silent, unlike those squeaky plastic mattress covers you get. In fact, the SureGuard Mattress Encasement is GREENGUARD Gold certified for low chemical emissions, so you can breathe cleaner, healthier air while you sleep.

This mattress protector comes in all the standard sizes, from Twin to California King, as well as a selection of non-standard sizes. There's the Short Queen for smaller bedrooms, the Super Queen for master suites, and the RV King for comfort on the road. One word of warning: the Utopia Bedding is not waterproof or spill-proof, but it is machine-washable for quick cleaning.
