What's the best mattress topper?

We think the best mattress protector for most people is the Tempur-Pedic Tempur Supreme.

Simple in construction, this mattress topper offers a lightweight solution for beds that are too firm, and can provide a good amount of extra comfort and support. Also, users claim that it lasts well, so you should get a good few years of service from this great-value mattress topper.

How thick should my mattress topper be?

Toppers can range in thickness greatly, from just an inch or two to eight inches or more. However, a happy medium for most is around four inches, and those under two inches should probably be avoided.

A thin topper is unlikely to actually provide much extra support or cushioning, and in use you're likely to 'bottom out', meaning your pressure points won't really be feeling any difference compared to your mattress alone.

Those that are too thick, however (especially standard memory foam toppers), will have you sinking deeply into the topper. While some might enjoy this, it can prove problematic when it comes to moving around in bed. You might find yourself feeling a little trapped, and if it doesn't spring back into shape immediately you could also struggle to get comfy when you change position.

While it all depends on your preference and what material you've chosen, we think between two to four inches is the best for a mattress topper.

How do I choose the best mattress topper?

When choosing the best mattress topper, you should consider exactly why you need one. If your current mattress is too soft, you should look for a firm topper that will help give you support and alleviate any sinking you currently experience. For example, the Amerisleep Lift Support is great for this, providing extra support while not being rock-hard. Firm topper are usually preferred by back and front sleepers.

If your mattress is too firm, your options are quite varied, ranging from traditional memory foams to feather down and down alternatives. These will help retain the support your firm mattress provides while adding some plush comfort. This will help you get comfortable easily, and will alleviate hip and shoulder stress if you're a side sleeper.

You might also be looking for a topper to help you stay cool at night. There are a number of options here, but a although many companies claim their toppers help dissipate heat, it's worth reading user reviews to make sure this is true.

Are mattress toppers good for back and hip pain?

They certainly can be. If you're a side sleeper you might find your back and shoulders ache when sleeping on a firm mattress. This may be because your spine isn't properly aligned in bed. A topper can help with this by providing extra depth and support while also taking stress away from your pressure points.

A firm topper can so the same for soft mattresses, and help you stop sinking too deeply into your bed.

What's the best way to care for my mattress topper?

As with most products, it's always best to see what the manufacturer suggests in terms of care. Some are entirely machine-washable, while other can't even be dry cleaned and can only be stop cleaned.

To help prolong the life of any topper, though, we'd recommend using a mattress protector as well. This will stop any soiling or stains damaging your topper, and as a bonus they can help stop the topper sliding off the bed through use.

Which is better: a gel or memory foam topper?

Memory foam toppers dominate the market, and can provide affordable, effective ways or both firming up or softening your current mattress. However, cheaper versions do often suffer from heat retention, which can make some overheat at night.

Gel and gel-infused foams perform much the same as memory foam toppers, but have technologies baked in that help dissipate heat. This is great if you tend to run hot, but many premium foams without gel have other ways of dissipating heat.
