Which is the worst mattress material? Our expert testers weigh in

When you're buying a bed, it's just as important to work out which mattress materials you don't like, as well as the ones you do. Now that I've sampled more than 40 mattresses, I know that I prefer the solid support of a hybrid mattress to the sinking feeling of memory foam, which is the worst mattress material for stomach sleepers like me. I know to steer clear of memory foam models in the mattress store and it's really streamlined my shopping experience.

Still, every sleeper is different, and the worst mattress material for me might sound like your dream bed. Memory foam isn't the most breathable or durable mattress material on the market, but it makes the best motion isolator, ideal for hot sleepers, and it provides near-perfect pressure relief for anyone who suffers with chronic pain.

As H&G's specialist sleep writer, I lead a team of expert testers in the search to find the world's best mattress. Together, we've tested some great beds, along with some real duds, and I've learned how subjective the concept of comfort can be. Take the Leesa Original Mattress: one of our expert testers loved the contouring comfort of the memory foam, while another hated how soft and squishy it felt beneath her body. One tester's dream bed is another sleeper's nightmare. All this to say that there's no such thing as the worst mattress material – only the material that feels worst for you.

Which is the worst mattress material?

I called on our team of expert testers to tell me what they think is the worst mattress material and why. You'll start to see how their likes and dislikes are informed by their sleep style, as well as the size of their budget. After each sleeper has had their say, I've identified some of our tried and tested beds that would solve whichever sleep problem they faced on their worst mattress material.

Which is the worst mattress material for hot sleepers?

Whether you suffer from night sweats and hot flushes, or you simply tend to run a little warm, you're what I call a 'hot sleeper'. In order to fall asleep and stay asleep, you need a mattress to dissipate heat and wick moisture, keeping you just the right side of cool and dry.

That's why your worst mattress material is memory foam. All that dense foam doesn't leave much room for air to flow, which means heat and moisture get trapped inside the mattress. It only gets worse in the summer, when all the air in and around the bed is already warm. The more the heat and moisture builds up inside the bed, the greater the chance that bacteria will start to breed, leading to a sweaty, unsanitary night's sleep.

One of our expert testers, Chiana, sleeps on a memory foam mattress. As a side sleeper who shares a bed, she appreciates the excellent motion isolation and contouring comfort of the memory foam, but she can't ignore the heat retention. She started testing the Emma Original Mattress last January, along with her partner, who's a hot sleeper. The heat retention of memory foam 'wasn't a problem for me, but it was for my partner, and it might be for you,' warns Chiana. 'If you're a seriously hot sleeper, I suggest you invest in the best cooling mattress, though you could always pair your Emma Original Mattress with a set of the best cooling sheets'.

If you're a hot sleeper, you need a breathable bed: these are a few of my favorites, from some of the best places to buy a mattress. Each of these beds is tried and tested by an H&G sleep expert and evaluated for comfort; support; motion isolation; and, most importantly, cooling.

Which is the worst mattress material for people with chronic pain?

If you suffer from aches and pains, then you'll know that the worst mattress material is a firm, inflexible innerspring. Those creaking coils barely compress beneath your body weight, so there's little to no cushioning for your joints. While the rigidity of an old-fashioned innerspring helps to keep your spine aligned, it comes at a cost to the rest of your body.

One of our expert testers, Casey, lives with fibromyalgia. It's a chronic pain condition that extends right the way across her body and often makes it impossible for her to fall asleep and stay asleep. For most of her life, Casey slept and suffered on old-fashioned innersprings and wondered if she'd ever find a mattress that met her sleep needs.

Then, she tested the Nectar Memory Foam Mattress, and it totally transformed her sleep experience. Casey needed a mattress with enough give to cushion her neck, shoulders, hips, and knees, yet sufficient support to bear her weight and stop her from sinking into the bed. In this medium-firm mattress, she found her perfect balance of comfort and support. 'I live with fibromyalgia,' reads the first line of Casey's mattress review. 'For a few hours each night, the Nectar Memory Foam Mattress helps me forget about it'.

Which is the worst mattress material for eco-conscious shoppers?

If you're an eco-conscious shopper, then your worst mattress material is memory foam. This synthetic substance is made to mold to the shape of your body, which means that it starts to incur indents and impressions. Within five or six years, your average memory foam mattress is starting to sag and losing support in the center. Soon enough, you'll have to replace it, and your memory foam mattress will end up in landfill, where it will take hundreds upon hundreds of years to decompose.

Camryn is one of our more prolific mattress testers. She's slept on all sorts of beds, from high-tech hybrids to plush memory foam models, and recently wrote a review for the Zinus Cooling Green Tea Mattress. She gave the gel mattress top marks for comfort, cooling, and cost, but she couldn't ignore its lack of durability. 'I'm wary that Zinus still uses fiberglass inside their mattresses and there are quite a few reviewers who claim that the mattress loses its shape after a year or so,' Camryn wrote towards the end of her review. 'If you're looking for the best organic mattress that's free from harmful substances and built to last, then you're looking in the wrong place'.

The best way to shop sustainably is to buy an organic mattress. Hear me out: a mattress is a major investment. When you're spending that much time and money to find your dream bed, you want something that will last: otherwise, you'll have to start the mattress shopping experience all over again.

Which is the worst mattress material for buyers on a budget?

If you're buying on a budget, then your worst mattress material is latex. Yes, latex is breathable, durable, and sustainable, but it's also incredibly expensive to source, froth, foam, and bake into beds. We're talking several thousand dollars for a Queen-sized bed, unless you're shopping with our affordable favorites, Earthfoam.

The Essentia Classic REM5 Mattress is the most expensive bed we've ever tested, and that's filled with natural latex. Our expert tester, Alex, said she 'couldn't review the Essentia Classic REM5 Mattress without mentioning the price. Retailing at $4,200 for an eight-inch Queen, this is by far the most expensive bed we've ever tested.' Although Alex argues that the performance matches the price, she acknowledges that the best luxury mattress is out of reach for the average American.

If you know you need a new bed, but you're working with a particularly tight budget, then I'd encourage you to narrow the search to the best affordable mattress. Most of these are memory foam models, which are cheap and easy to manufacture, but still offer excellent comfort and support. As a general rule, memory foam and innerspring mattresses are less expensive than hybrids or latex mattresses.

If you've got your eye on a more expensive mattress material, then I'd encourage you to shop the mattress sales. If you're smart about it, you could save hundreds of dollars on your dream mattress and get latex for less.
