Not too unlike wolves moving in a pack, the WIRED Reviews team often bands together to help one another out with product reviews. I’ve tested hundreds of beds and brands over the years, so I get pretty jazzed when something I haven't tried is on the prowl, but I'm a singular tester with only so many nighttime hours a week. Thankfully, my teammate Molly Higgins stepped in to test Wolf's 12-Inch Memory Foam Hybrid Essential Medium-Firm Mattress. Not to spoil anything, but it made our list of the best mattresses of 2025 for a reason—and we test a lot of beds, so that’s saying something. I had to know for myself and see this mattress in the wild (my guest room) to determine how well it performed. Here’s what I can tell you: Watch out, other mattress brands. This one’s the “Big Bad Wolf,” and I was blown away. Wolves’ Den Photograph: Julia Forbes I thought long and hard about which mattress would be a good introduction to all things Wolf, a brand that's been around since 1873, and landed on a slightly different model than the one Molly tested: the 13-inch Memory Foam Hybrid Premium Firm. I wish the name were just “Wolf Hybrid” to keep things succinct, but the construction let me know what I was getting into. I wanted something that would serve as a baseline, so to speak. This would include key performance indicators like temperature control, responsiveness, edge support, and motion isolation—all key terms for mattress testing. What’s cool is that each mattress is made to order at Wolf’s Texas-based factory. Also cool? The cooling cover, which felt cool to the touch right away and did a pretty stellar job of maintaining that feel all night long. It’s the first mechanism within the bed’s quilted topper meant for temperature control. Under the quilted surface is a rayon fire barrier (safety first, after all), plus a gel memory foam to supply both cushioning and cooling. To round everything out, a firm-feeling quilted foam layer is stacked at the bottom. Within the bed is a firm comfort layer that’s one inch thick, plus an additional inch and a half of gel memory foam, which serves the dual purpose of providing pressure relief and temperature control. Another inch of support foam is nestled atop the 8-inch pocketed coils. This coil type is intrinsic for targeted support, as individual coils will adapt to support the specific weight of the sleeper on the top of the bed. This is all placed atop a foam base layer, which is meant to help the coils support the sleeper, as opposed to overt pressure from the base underneath. If you're keeping score, that's nine layers in all. Now, that’s a lot of technical information. What does it mean for you? First, I’m always an advocate for a hybrid mattress like this one, as you can partake in all the cushioning and pressure relief the top layers of memory foam have to offer. Wolf’s memory foam is also CertiPur-US certified, so it’s passed safety tests to verify there are no hazardous chemicals. The coil unit underneath helps to keep air circulating so that you don’t experience the heat retention that foam can usually garner by itself.

This is pretty standard for mattresses in a box, but something about Wolf’s felt extra buttoned-up. Once the mattress was set up on the frame and 24 hours had elapsed to give the mattress some breathing room (which you should always do with mattresses in a box), it was go time.
