There are so many factors in getting a good night’s sleep — your mindset, your overall health, your evening habits, your mattress. While each plays an important role, sometimes a new mattress is the quickest route to better ZZZs. Especially if it's been a while since you updated (and especially if your back hurts when you wake up in the AM: that's a red flag for a worn out mattress).

A mattress is definitely an investment, but as it turns out, there's no better time to buy one. Amazon's second Prime Day is going strong — a surprise bonus ahead of the holiday rush — and tons of bestselling, top-rated mattresses are majorly marked down. And believe it or not, Amazon is not the only place to shop. Because retailers are overstocked and looking to move merch, there are lots of great spots to score a top-quality mattress on sale today.

Not sure where to even begin? We've got you. To get the right specs, we talked to two doctors. Then, applying their criteria, we scoured the sales and pulled together a list of deals for you.

What did the docs have to say?

“A better mattress absolutely can help with sleep,” Christopher Winter, M.D., of Charlottesville Neurology and Sleep Medicine and author of the book The Sleep Solution: Why Your Sleep Is Broken and How to Fix It, tells Yahoo Life.

There are a few specific signs that it’s time for a mattress upgrade, according to Winter:

  • You’re moving around a lot at night. “A lot of times, pain or discomfort makes you move a lot to try to get comfortable,” Winter says. You might not even realize this is happening. Check out the status of your sheets in the morning—if they’re all bunched up or twisted, it’s a good sign you were tossing and turning. Or, if you sleep with a partner, Winter recommends asking if they’ve noticed you moving around at night.

  • You’re sore in the morning. The wrong mattress can put pressure on your hips, shoulders, and knees, causing stiffness and soreness in the morning, Winter says. “Soreness is a great way to find out if your mattress is supporting you the right way,” he says.

  • You’re overheating. If you’re getting hot and sweaty at night, your mattress could be to blame. “Some mattresses that offer more support can sometimes make you feel hot,” Winter says. “Sweating in bed is a big thing people often put up with, but they shouldn’t.”

Winter recommends making a list of what you need—more joint support, a softer feel, a cooling environment—and looking for options based on that. If you have a partner, Winter suggests sitting down with them and making a list of the factors that are important to each of you in a mattress. “If they widely diverge, you probably want to look for a mattress that you can customize for each side,” he says.

Not sure what you need? Opt for a medium-firm option, Harrison A. Linder, M.D., pain management specialist with The Center for Interventional Pain Medicine at Mercy Medical Center in Baltimore, MD, tells Yahoo Life. ”They tend to be firm enough to offer support for back and front sleepers, but still offer some cushion for those that prefer to sleep on their sides,” he says.

And, if you have back pain, Linder says it's important to make sure your mattress offers the right support for you. "Just like trying to maintain good posture while standing and sitting, it is important to keep the components of the back — vertebral bones, intervertebral disks, and all associated ligaments — in healthy positions while sleeping," he says.

It's also a good idea to see how the mattress feels, Linder says. "This is not a simple case of 'one size fits all,'" he adds. (Most online mattress retailers have fantastic return policies, so you really can do a trial run before you fully commit.)

Here are a few options to get you started. Bonus: They are all on sale right now and they all have great return policies.
