4 incredible mattress topper deals to buy before Prime Day ends at midnight

There are some outstanding mattress topper deals in the Prime Day sales – a number of our best mattress topper picks have come in for a price drop. We’re on day two of the Amazon dealathon, so you don’t have long to claim if you want to snap up one of these offers. 

A mattress topper can completely change the feel of your bed – firming or softening up the sleep surface, or introducing a soothing memory foam hug to an innerspring mattress, for instance. They’re great if you don’t quite have the right mattress for your sleep style or body type. They’re also the most budget-friendly way to upgrade a tired, old mattress. Many of our best mattress picks have a topper version that uses the same materials the full mattress, which can be a way to get some of that quality and sleep feel for a much lower price (a prime example is the Tempur-Adapt topper, currently on sale at Tempur, rather than via Amazon).

If you’re on the fence between buying a topper or hunting out a cheap mattress, you should know that while the Prime Day mattress deals are a little underwhelming (with the exception of a couple of excellent Casper sales), there are some strong Prime-alternative mattress sales going on at the big bed brands. 

This roundup is mostly Amazon deals, but some are from rival-Prime events. For the former, you will need to be a Prime subscriber to claim. However, it is possible to use the free trial and cancel if it doesn’t suit you.

What exactly is a mattress topper?

A mattress topper is a thick (usually 2-4 inches) layer that sits on top of your existing mattress, often secured by elasticated straps or a stretchy skirt. It differs from mattress protectors (a thin cover purely to provide a protective barrier) and mattress pads (these are thinner).
