The 8 Best Firm Mattress Toppers

Countless reviewers say this topper is amazing at addressing back and neck pain — and if you're not a fan of memory foam, it's the perfect alternative. It meets Global Organic Latex Standards, has passed Oeko-Tex Standard 100 requirements, and comes with a five-year warranty.

This topper has saved us hundreds of dollars because now we don't have to buy another mattress. We both sleep more soundly, and it provides the firmness that he needs without while it's still soft enough to be comfortable for me."

With a density of just under 4 pounds per cubic foot, this hard topper is one of the densest memory foam mattress toppers on this list (remember, density equals firmness), and comes in a full range of bed sizes for every room. This 3-inch memory foam mattress topper strikes a great middle-of-the-road height that will give you plenty of support without making it hard to find sheets that fit.

Even better, it also solves one major dilemma a lot of people have when it comes to memory foam: Instead of retaining heat and making sweaty sleepers even hotter, this topper has a ventilated and gel-infused design that allows it to distribute body heat more easily and allows for better airflow. The topper comes with a removable, washable, hypoallergenic bamboo-rayon cover and four adjustable straps to keep it in place. It's no wonder after 8,000 Amazon reviews, this topper has earned a glowing, 4.5-star rating. It also comes with a three-year warranty for peace of mind.

Positive Amazon review: "The biggest problem I have with foam inserts on a mattress is the fact that I'm an incredibly hot sleeper - like two fans on me in the winter, personal AC unit next to me in the summer hot. This mattress topper is noticeably cool. In fact, when you climb in to bed you can feel how cool the pad is on your skin. [...] This topper is a great solution to getting more life out of a mattress, even if you're an incredibly hot sleeper."

It's a bit pricier, but this 3-inch memory foam mattress topper has a density of 4 pounds per cubic inch, making it a bit firmer than the pick above. While the pick above is still a better value for what it is (and has features like the built-in ventilation that make it a standout choice), this high-density memory foam topper might make sense as an upgrade if you're looking for the firmest memory foam option. It consists of 3 inches of Visco elastic memory foam, which feels springy and conforms to your body, but also cradles it in a firm, supportive way — you aren’t going to sink into this mattress topper. It’s backed by a three-year warranty.

Positive Amazon review: "If you like EXTREMELY FIRM mattresses... this will work for you."

A hard truth: The denser the mattress topper, the more expensive it tends to be to produce and to buy. But this high-density memory foam mattress topper is amongst the cheapest truly firm options out there. It has a density of 3.5 pounds per cubic inch, which is lower than the other picks above. But, it comes in a bunch of different thicknesses and designs so you can customize it. And, like others on this list, it is made with a gel-infused memory foam (which has ventilation built in) and a bamboo cover to help keep hot sleepers cool throughout the night. But perhaps the best feature on this firm mattress topper is it's 10-year warranty. It has earned more than 4,000 reviews.

Positive Amazon review: "The topper provides a firm support WITHOUT pressure on the hips, shoulders and neck. The 3.5 lb density foam offers less of the feeling of sinking into the topper, and does a nice job of controlling body heat. It also stays firmly in place on top of the mattress. Great product!"

When the other person moves , I do not feel it, the bed doesn’t move with this on it. [...] I'm also no longer waking up in pain.”
