The Best Firm Mattress of 2025

“I loved that the Plank Firm Luxe is like having two firm mattresses in one. It’s a real bonus to be able to choose between firm and extra firm, and each side also offers excellent edge support and temperature regulation.” –Garen Glazier, Product Testing Team Member

If you’re in the market for a firm mattress, the Plank Firm Luxe from Brooklyn Bedding offers excellent bang for your buck. The reversible design features a firm (7) feel on one side and an extra firm (9) feel on the other, the latter being one of the most supportive surfaces our team has tested. When you want to change things up, simply flip over the Firm Luxe — the mattress is relatively lightweight and easy to lift with a partner.

Why We Like It

During hands-on tests, most of our back and stomach sleepers preferred the firm side of this mattress. Some testers who use these positions and weigh more than 230 pounds also felt comfortable on the extra firm side. If you’re a side sleeper, chances are you won’t receive enough cushioning from either surface, though some on our team gave the firm side favorable ratings.

The Firm Luxe’s perimeter feels quite stable, so the mattress earned high marks for edge support. Most of us encountered little to no resistance when moving across the surface. We also found that the mattress slept cool, though people who are “hot sleepers” may want to consider the cooling GlacioTex cover upgrade. Other notable qualities include below-average pricing and a wide size selection.

The firm side contains fibers quilted into the cover, followed by two dense foam layers. Light contouring ensures you’ll get some cushioning from the mattress without too much sink or hugging. On the extra firm side, a single foam layer keeps your body on an even plane and barely conforms at all. Pocketed coils located between the comfort systems serve as the support core for both sides of the mattress.

Standard Firm Luxe models come with knit polyester covers. For an extra fee, you can swap in a cover made of GlacioTex phase change fabric engineered to capture and release body heat. Brooklyn Bedding offers a dozen sizes for the mattress, including a split California king for couples who share adjustable beds and several RV-friendly options.

Standard ground shipping is free within the contiguous U.S. Each order is backed by a 120-night trial period and lifetime warranty.

“The firm version of this mattress has all the sturdiness I need while layering on some cushioning. For me, it was a great mix of firmness and comfort.” –David Rubin, Director of Product Testing

The firm Brooklyn Bedding Signature Hybrid feels remarkably sturdy thanks to dense, responsive foam layers in the comfort system and robust pocketed coils. Even if you opt for the additional pillow-top, this mattress delivers plenty of reinforcement and shouldn’t sink too much beneath your weight.

Why We Like It

Our testing team found that the firm Signature Hybrid is best suited to back and stomach sleepers who weigh at least 130 pounds, and side sleepers who weigh over 230 pounds. Latex-like VariFlex transitional foam paired with a strong coil system ensures plenty of support and a noticeable bounce when you get into bed. Those who use these positions and weigh less should consider the medium soft (4) or medium firm (6) designs instead. During tests, the firm model excelled at edge support and ease of movement. Temperature control was another strong point, though people who run exceptionally hot in bed may need the cooling pillow-top upgrade to sleep comfortably.

How Does It Feel?

The firm Signature Hybrid’s topmost layer is composed of TitanFlex polyfoam, a dense material that contours evenly to distribute your weight, align your spine, and alleviate pressure points without sinking too much. Responsive transitional foam reinforces the supportive surface. Pocketed coils and dense base foam in the support core provide excellent overall stability and protect the edges.

Standard Signature Hybrid models come with covers made of soft, breathable cotton. You can add an extra foam layer encased in GlacioTex fabric, which makes the mattress feel softer without affecting its overall firmness. GlacioTex is engineered to dissipate heat on contact and feel cool at all times. Note this upgrade will increase the cost of your order by roughly 30%.

Brooklyn Bedding’s Titan Plus combines above-average durability and edge support, making it a good choice for sleepers over 230 pounds. It also has an attractive price-point, so shoppers on a budget can still take advantage of its benefits.

Why We Like It

The cover contains gel-infused memory foam designed to provide subtle pressure relief while drawing heat away from the sleeper. During our temperature control tests, thermal mapping tools detected very little heat buildup on the surface.

The rest of the hybrid structure integrates foam comfort layers with a robust pocketed coil core. Our testers noted that the layer of TitanFlex polyfoam adapted to their bodies without conforming too closely.

How Does It Feel?

The Titan Plus has an 11-inch profile and a firm (8) feel. The stomach and back sleepers on our testing team found that the solid surface helped encourage proper spinal alignment, but those under 130 pounds and our side sleepers reported that it felt a little too firm.

The pocketed coils are designed to stabilize the top layers while encouraging a spinal alignment. Two inches of high-density polyfoam reinforce the base. The Titan Plus uses gel infusions and pocketed coils designed to help remove excess heat, and people who tend to sleep hot can opt for an additional cooling top panel.

“There’s no doubting the firmness of the Dawn Luxe, but it also managed to soften impact around my joints with a just-right level of cushioning. Another thing I liked was that it stayed firm around the perimeter, including when I was sitting on the edge of the bed.” –David Rubin, Director of Product Testing

Made with high-quality materials, the Helix Dawn Luxe has a firm (8) feel designed with stomach and back sleepers in mind. Not only is this one of the firmest mattresses we’ve tested, it also features three foam layers in the comfort system to alleviate pressure points.

Why We Like It

Testers felt they got a good balance of support and contouring from the zoned support core, which focused its support on the back and hips while contouring the shoulders and legs. Our tests also showed that the thicker gauge coils reinforced the perimeter and reduced sagging along the edges. The high-density polyfoam that forms the mattress’ base helps ensure that the upper layers function optimally.

We recommend the Helix Dawn Luxe for sleepers who want a higher-end firm mattress designed to provide good support. However, while back and stomach sleepers over 130 pounds are likely to enjoy this mattress, side sleepers may need something that provides a little more contouring.

How Does It Feel?

The Dawn Luxe features a breathable Tencel cover and a pillow-top cushioned with dense memory foam. Our testers reported that the foam interior gently contoured the body, and the cover kept the surface cool. Beneath the pillow-top, there’s also a layer of gel-infused memory foam that is engineered to alleviate pressure points and promote proper spinal alignment.

Two layers of polyfoam complete the comfort system. We found that the thicker top layer provided a good balance of adaptive support and subtle bounce. The transitional polyfoam layer provided even contouring while absorbing shock from the steel springs.

“In its firmer models, the WinkBed scored well in virtually all categories during my testing. Strong coils in the middle kept my spine in a neutral position while maintaining support for my lower back. The sturdy edge support ensured reliable firmness across the entire mattress surface.” –David Rubin, Director of Product Testing

A firm mattress sometimes comes at the expense of pressure relief, but the WinkBed manages to merge support with comfort. With four different firmness options — medium soft (4), medium (6), firm (7), and Plus (8) — this mattress can accommodate a range of sleep positions and body sizes.

Why We Like It

Our testers reported that the coils provide robust support. This quality was most evident with the firm and Plus models. Steady airflow through the coils and the moisture-wicking Tencel cover also helped the WinkBed perform well during our temperature control tests.

We also found that the mattress does a great job of providing pressure relief at a variety of firmness levels. This makes the WinkBed a good choice for sleepers who prefer a firmer mattress but still need solid support at pressure points. We recommend either of these models to anyone looking for a balance of firmness or pressure relief.

How Does It Feel?

The WinkBed integrates contouring and bounce by combining polyfoam comfort layers with different-sized coils. The comfort system for standard models consists of a Euro-top with a eucalyptus-derived Tencel cover designed to wick away heat while gently cushioning pressure points. This is followed by a layer of adaptive polyfoam. In the Plus model, the comfort layer is composed of latex for added support and responsiveness.

Zoned coils make up the support core. Thicker coils rest beneath your midsection to push back against extra weight in your torso and hips, while thinner coils cradle the head and legs. The perimeter is also reinforced to limit sinkage when you sleep near the edges or get in and out of bed.
