This Cover Has a Backstory:

In the fall of 2023, we started selling pocket coil units to DIYers building their own mattresses. Texas Pocket Springs has been selling coils to mattress makers for decades, but we were newbies to the DIY space.

Over the first year of engaging with the community on Reddit and talking to the DIYers buying our coils, we picked up on a clear theme: the zip-up mattress covers on the market had room for improvement. So in the fall of 2024, we developed our first DIY mattress cover. Our goal was to create a high-quality DIY cover with a built-in fire barrier layer—something other options were missing—while keeping the price point in line with other available covers.

The cover was a hit! We've heard from hundreds of customers who appreciated the FR layer and loved the quality. But as DIYers, we're always thinking about how we can make things better, right? So we did.

We took all the feedback and pain points frequently mentioned on Reddit and designed a premium DIY cover from the ground up—the best mattress cover you can buy for your build:

• Sturdy bottom layer: Helps keep your foam and coils from squeezing down into the slats. (We still recommend slat spacing of no more than 3 inches.)

• Sturdy side panel: We added stitched ridges to make the sides less stretchy while maintaining a premium feel. This reduces the bulging effect you’ll often see when using coils in other DIY covers.

• Mid-zipper: This one’s a big deal. Most zippered covers attach the zipper to the top or bottom panel because it's cheaper to manufacture. Placing the zipper in the middle of the side panel requires more cutting and stitching—but it makes assembling your mattress much easier. You'll also find a fabric flap behind the zipper, making it easy to zip up without snags.

• Stretchy cotton top: Adding a cover to your build will always firm it up slightly, but a stretchy top layer helps minimize that change. Our top panel has just the right amount of stretch, with enough body to mask the rubbery feel of a latex top layer. It also has a really nice texture you’ll enjoy through your sheets.

• Waterfall edges: Partly for style, partly for comfort—the top panel wraps around the corners so the seam between the top and side panels sits about 1 inch below the top of the mattress. That means no annoying seam rubbing through your sheets, and it gives your build a finished, store-bought look.

Note: To get the amount of stretch we wanted in the top panel, we had to eliminate the FR layer from it. If having a fire barrier layer is important to you, check out our original Organic Cotton Cover.

Pro tip: It’s never a bad idea to size up on height. For example, if your build is 12", it’s totally fine to order a 13" cover.
