9 best memory foam mattress toppers for a supportive night's sleep

Score: 93/100

The one to choose if you want the benefits of bamboo, this premium Panda design combines 2,100 micro-springs with orthopaedic grade memory foam and to completely transform your bed – giving you the feel of a brand-new mattress, without the hassle or expense of replacing it.

It also boasts a layer of breathable BioCell foam, a ventilated mesh border and an anti-slip base to prevent it from shifting during the night. The washable cover is made from bamboo, which is naturally anti-bacterial, temperature regulating and hypoallergenic.

The medium-firm design was a huge hit with all types of sleepers, who said it was comfortable, supportive and “luxuriously soft” to snooze on. Just note, it’s on the heavier side and will add significant depth to your mattress.

We also trialled Panda's Bamboo Mattress Topper, a 5cm design with a bamboo cover, which scored 89/100 in our tests.

Like our winners, this Simba design is packed with foam and pocket springs for an airy, well-supported sleep. Again, this proved a panel-pleasing combination – testers loved bedding down on the firmer cushioning.

In the lab, our experts noted that its fit was less exact, coming up slightly oversized. While this explains the difference in scores, it’s not anything that would drastically impact your sleep – and indeed didn’t for our panel of testers.

You can wash the cover too, and it’s suitable for storage (even if its size may make this tricky). Another premium buy.

If you want to be sure you won't feel a single spring through your topper, this one from Emma is a good bet as it’s nine centimetres deep – the highest on our list. There aren’t any straps, but a fitted sheet kept it in place on test.

Everyone raved about sleeping on it thanks to the cushioning and comfortable support. They all said they’d recommend it to others as well.

Flip flopping is no bad thing with this mattress topper – you can alternate between different support levels on either side (one’s soft, one’s firm) until you decide which is just right.

Our panel also liked that you could remove foam if needed, making the design even more flexible. It impressed when it came to comfort, support and overall quality, too. It sits smoothly, but there aren’t any straps, so you’ll need a well-fitting sheet to keep it in place, especially if you’re a fidgeter.

This topper features cooling gel-infused beads and a washable Tencel cover to regulate your temperature overnight. The five centimetre thick memory foam has also been crafted to relieve pressure and provide “cloud-like support” for all sleeping positions.

It did an excellent job of keeping panel members cool while they snoozed, and they said it was ultra soft and comfortable to lie on, too. “I would 100% recommend this topper, it changed the comfort of my mattress straightaway,” said one satisfied tester.

It was a little tricky to fit and the straps are on the short side, but once in place, there’s an anti-slip backing to prevent it from moving around. It’s also a little awkward to roll up, but that didn’t put our testers off – in fact, everyone said they would continue using the topper.

Score: 83/100

A quick disclaimer: this isn't made with memory foam. Instead, it uses a polyester fibre filling that's designed to mimic memory foam's rebounding, supportive effect and keep you cool at the same time.

We've included it because it's notably cheaper than the rest of the products on our list, and our testers liked the product overall. While it was a smidge smaller than our double mattress, it's smooth to lie on and quiet at night. It lived up to its breathability claims too and all our testers said they'd recommend it.

Ultimately, it won't offer exactly the same cushioning as one of the genuine foam options above, but if you are on a budget, it's the next best thing.

Score: 83/100

Designed to regulate your temperature thanks to cooling gel in the foam and a moisture-wicking (and machine-washable) cover, this is another good pick if you get hot at night. In fact, most testers found it nice and breathable.

It scored highly for comfort too, and its overall design ticked our boxes, lying smoothly. While it fitted well, it moved a little for some, and because it’s thick, it may be trickier to store. But everyone said it improved the quality of their sleep, which is the most important criteria, after all.

Score: 82/100

Boost your mattress with this spring-blocking and breathable design from REM-Fit. Our testers praised how quiet it was to lie on, how comfortable it was (for everyone!) and its overall quality design.

The fit was a bit mixed, so we’d suggest checking that the measurements match up to your existing mattress before you buy. And while it has sturdy elastic straps, it moved for some fidgety panellists. But generally, it was a hit – so much so that one tester said it was like having “a high-quality mattress on its own”. That’s great value for money, if you ask us.
