As a mattress topper tester, I know that the right bed topper can transform your sleep set-up. Luckily, there are plenty of high-quality mattress toppers on sale ahead of the 4th of July, so giving your mattress a reboot just got cheaper. One standout deal gives you the chance toget 40% off the Tempur-Adapt Topper at Tempur-Pedic, with a queen now $251.40 down from $419. 

Tempur-Pedic isn't the only brand behind some of this year's best mattresses to offer great savings on their bed toppers. Bed-in-a-box brand Casper has also knocked 10% off its Comfy topper, while ViscoSoft is slashing all their toppers by 25%. 

Here, I've rounded up the top five mattress toppers to buy in the 4th of July mattress sales. Each offer to boost the comfort of your mattress, plus they all appear in a our best mattress topper guide.

Do mattress toppers work?

Some people wonder if mattress toppers actually work. After all, shouldn't a mattress alone be enough for a comfortable sleep? However, mattress toppers can be great for fixing any issues that are affecting an otherwise good, supportive mattress. 

That said, there are some mattress toppers that can be a waste of money and can even exacerbate any problems you're having. For example, some mattress toppers are too thin to make any impact, while others are too tall to be supportive. If you want to know whether a mattress topper will actually work, look for one that is firm or soft enough for your sleep style and between two and four inches tall.
