With the best mattress toppers you dramatically increase the lifespan of that bumpy old mattress that's losing you sleep at night. A topper is a thick layer that sits on top of your existing mattress, and is usually kept in place with elastic straps. They come in a variety of materials, from memory foam and even springs through to feathers and synthetic stuffing. Don't confuse these with the best mattress protectors, which are thinner layers that simply shield your mattress from spills and stains, and aren't designed to change the feel of the sleep surface.

If your old mattress simply isn't just right, choosing a suitable mattress protector can get it back into the Goldilocks zone. Whether you want to firm up an unpleasantly soft mattress or give the feel of the best memory foam mattresses to an old spring model, a mattress topper is the ideal solution, and can save you having to go out and spend a lot more on the best mattress.

There are plenty of mattress toppers on the market, and as their manufacturers really want your custom you'll find that there's almost always a deal to be had. To save you lots of looking around, we've reviewed the best mattress toppers in terms of both quality and value, in one handy post. The price widgets accompanying each entry will automatically pull in the cheapest options (including any Amazon Prime Day deals over 21-22 June). 

Finally. if you're on the fence about whether a new mattress entirely might be a better idea, head to our best cheap mattress deals – it might not cost as much as you'd thought.

Thickness: 5cm
Filling: Foam, polyester cover
Size: Single, Double, King, Super-King
Reasons to buy
+Very comfortable and supportive+Hypoallergenic+Isolates movement 
Reasons to avoid
-Will be too firm for some

The Eve mattress topper is designed to add a luxurious layer of comfort to your mattress. Beyond that, it also provides a generous helping of support. It’s made from 5cm of the same foam found in the company’s original mattress: there’s a 2cm open cell comfort layer, and a 3cm base foam layer for increased support. It also comes with a hypoallergenic, removable and machine-washable 100% polyester cover, which acts to increase its life.

This mattress topper comes with straps at both ends that hug your mattress, keeping it firmly in position as you sleep. The foam regulates your sleeping temperature, so you’ll stay cool throughout the night. It also serves to reduce motion transfer, which means you’ll notice less partner disturbance throughout the night. And its very breathable – in fact, Eve claims it’s around 30 times more breathable than traditional memory foam. This is an expensive option compared to other products on this list. But overall we think it's the best mattress topper you can buy – head to our Eve mattress topper review to find out more.

2. Simba Hybrid topper

The best hi-tech topper with springs and foam

Specifications
Thickness: 7cm
Filling: Foam, springs, latex
Size: Single, Small double, Double, King, Super king
Reasons to buy
+Supportive springs+Cooling open-cell foam+Anti-slip base
Reasons to avoid
-Pricey

The Simba Hybrid mattress topper is almost like a mini-mattress in itself. This complex model includes four separate layers: a breathable top cover, a layer of synthetic latex, a layer of mini 20mm conical springs (in a polyester pocket), and a layer of zoned foam (called 'Simba-Pure'). There's also an anti-slip base to keep it securely in place on your bed. It's on the chunky side but not ridiculously thick at 7cm. It's (understandably) pricey, there's always a chance you might be able to snag a Simba discount code to knock a bit off. Also note that this topper uses a lot of the same materials you'll find in Simba's mattresses (see our five-star Simba Hybrid Pro review for more on that) – so this could be a way of getting all that expertise for a much lower price than a whole new mattress.

It is extremely soft as well as supportive so it will help prolong the life of your mattress whilst bringing the added benefit of a bit of extra comfort. You can tighten or loosen this mattress topper with its adjustable buttons, meaning that you can have it nice and taught if you like a firmer mattress, or have it looser if you like a softer sleeping foundation. That's a great feature for anyone worried that adding a mattress topper to your bed might negate the benefits of your carefully selected mattress. As an added bonus, the top layer is easily removable and machine washable. When you first get this mattress, give it time to air out and plump it up, as the feathers can become compressed when packaged.

This filling is contained within a removable, washable and naturally hypoallergenic cover that’s made from bamboo, so it's good for allergy sufferers too. The foam is also punctuated with tiny capsules of cooling gel that should help prevent you overheating throughout the night (in practice, it still traps heat a little).

Add it onto a spring mattress and this topper will mould to your shape to relieve any pressure on the muscles and deliver a soothing night’s sleep.

This is cheaper than the other memory foam entries on our list, and some reviewers have had issues with it not lying quite flat. Also note that while it's listed as machine washable, this refers to the top cover that stretches over the foam layer.

How to find the best mattress topper

What do you need to consider when choosing a mattress topper? First look at what's inside it. As with pillows, mattress toppers come with a range of fillings. Memory foam toppers work well if you want something to mould to your body and provide custom support and pressure-relief. Synthetic fillings such as polyester, polyurethane and latex can be a great option if you suffer from allergies (although almost all of the best mattress toppers will offer a hypoallergenic certification).  

It's also about the level of comfort you're looking for. How firm your mattress should be depends partly on how you like to sleep – if you're lying on your back sleeper, you might want something firmer to support you under your hips and shoulders, while if you lie on your side, you might want a softer surface to avoid achy shoulders – but it's also a matter of personal preference. 

Finally, think about how thick you want your topper to be. To cover up rogue springs, the best mattress topper will be nice and thick – but go too deep and you might need to buy new sheets to fit. Now read on to discover the best mattress toppers to help you upgrade your sleep.
