The 6 Best Firm Mattress Toppers Of 2023 To Perfect Your Sleep Setup

Saatva is a fan-favorite mattress company that uses sustainably sourced, organic materials in its beds and accessories. This mattress topper comes in three different materials: a graphite foam, a natural latex foam, and a high-density foam. For folks seeking a firmer topper, we recommend the latex model, as it's going to be more responsive and durable than the other options. 

There is only one firmness option for each of the models, and the latex version is a true medium-firm. It's on the slimmer side compared to others on this list, so if you're truly not a fan of your current mattress, this 1½-inch model might be too thin for you. However, that also means you won't sink too deeply into the topper, which is good news for stomach and back sleepers. Reviewers of all sleep styles seem to be pleased with the support and cush of the latex version.

The organic cotton cover isn't removable, so you'll have to stick to spot cleaning. But one great perk of this topper is that it comes with elastic straps to make sure it doesn't slide around on top of your existing mattress.

Alongside Avocado, PlushBeds is a leader in sustainably sourced mattresses and sleep accessories—and its 100% Natural Latex Topper is no exception. With certifications like ​​OEKO-TEX Standard 100 and GreenGuard Gold, this slab of organic Talalay latex wrapped in an organic cotton cover ticks a lot of green boxes.

Speaking of the cover, it is removable. If you want to wash it, PlushBeds recommends you hand wash and air dry the material. Several reviewers say the combination of the cotton cover and perforated latex makes for a cooler sleep surface than other foam toppers that they've tried. 

With five different firmness options and two different thickness options (2-inch or 3-inch heights), you can customize your PlushBeds topper to suit your existing setup.

Side sleepers could probably stand to get away with a medium or medium-firm version, while back and side sleepers wanting a firmer surface should stick to medium-firm or extra-firm. PlushBeds also recommends that anyone seeking a true extra-firm surface (especially folks weighing over 250 pounds) choose the extra-firm model.

This topper from Avocado uses GOLS-certified organic latex to create a luxurious, supportive feel. Unlike memory foam, latex is bouncier and more responsive. If you like the feeling of sleeping on top of your bed versus in your bed, the firm version of the Avocado Organic Latex Topper topper might help achieve the firmness you're looking for. 

It also gets rave reviews for maintaining a comfortable temperature during the night—that's thanks to the thick layer of organic, moisture-wicking wool at the top. Not into wool? They also have a vegan version of this mattress topper, which swaps cotton for wool (but is the same price). Speaking of price, this topper is on the higher end. However, if your priorities are temperature regulation, eco-friendly practices, and sustainable materials, the extra bucks might be worth it. 

A few considerations: There isn't a removable cover on this topper, so you'll need to spot-clean as you go. Reviews are also mixed as to whether this topper slides around on top of a mattress. A few folks suggest layering it on top of a grippy surface (like a rug grip) to avoid needing regular adjustments.

Although memory foam is definitely not as firm as latex foam, this topper from TEMPUR-Pedic still provides a thick, 3-inch slab of comfort to any mattress. Memory foam provides a cradling sensation, so this topper is a better pick for side sleepers than back or stomach sleepers—folks who move around often in the night are likely to feel stuck. Although it's definitely softer than the option on this list, plenty of reviewers still say the foam topper is on the dense side. 

The cover on the TEMPUR-Topper Supreme is removable for easy washing. And while memory foam is notoriously warm, not many reviewers complain about sleeping hot on this topper made of it. If sleep temperature is a concern for you, you can upgrade your topper's cover to a "cool-to-the-touch" material, which costs an additional $60. 

TEMPUR-Pedic has been a household name for decades thanks to its signature memory foam material (you might have witnessed a demo of someone walking on the foam with a glass of red wine at your local mall in the aughts?). However, the foam isn't made from sustainably sourced or recycled materials. On the upside, you're likely to find a TEMPUR-Topper to lie on at a mattress store near you to try before you buy, which is helpful as TEMPUR-Pedic doesn't offer trials or returns for toppers.

The thinner profile of the Silk & Snow mattress topper is great for shoppers who don't want to add too much height to their current mattress. Completely GOTS and GOLS-certified, the organic latex is sourced from Sri Lanka and then manufactured into a mattress topper in Canada or the U.S.  

One big perk of this latex topper is that it comes with a removable organic cotton cover that's also machine-washable (so there aren't any excuses when spring cleaning rolls around). You can even purchase additional covers separately if you so choose. 

Silk & Snow's topper comes in a medium or firm option. Since it's rather thin—we couldn't find an exact measurement, but it looks to be around 1½ inches—you should consider how much you're trying to firm your current mattress. If you're looking to make a big change to the overall feel of your bed, you're likely better off with the firm version. Side sleepers, on the other hand, might prefer the feel of the medium.

It's unclear how Sleep On Latex sells an organic latex foam topper for so much less than competitors like PlushBeds and Avocado, but we're glad they do. The brand even has many of the same credentials and business practices, such as using GOLS-certified organic, fair trade foam. 

The Pure Green Natural Latex topper comes in three different thickness options and three firmness options. Side sleepers might prefer the feel of the medium topper, while back and stomach sleepers are likely better off choosing the firm. There's also an option to add an organic cotton cover if you don't like the feel of perforated latex through your sheets—however, the perforation should help regulate temperatures nicely for hot sleepers. 

Like Silk & Snow, PureGreen also sources foam from Sri Lanka but manufactures all of its beds and accessories in Chicago. Plus, the toppers get rave reviews on Amazon—just note that the return policy and warranty might vary depending on where you make your purchase.
