The Underlay by Mellow Mat™ is an additional super soft memory foam layer designed to sit under your Mellow Mat to create an even more comfortable floor. It adds 20mm of thickness. When used with the Mellow Mat, the total thickness in the middle area is 50mm! If you love your Mellow Mat, you'll love it even more with this accessory. 

Our custom non slip fabric covers both the top and bottom so there's no sliding around. Created slightly smaller than your Mellow Mat so the edges will still touch the floor. (new Mellow Mats may need a few weeks of use for the edges to sag to the floor)

Light weight and easy to wash.

    Wasn't sure 20mm would make a noticeable difference but my knees definitely feel it after a long day standing at my desk. The memory foam layer squishes down just enough without bottoming out, and it stays put under the mat instead of sliding around.

    Alexander X. ★★★★★

    The extra 20mm under my mat turned it from comfortable into genuinely luxurious—my hips and knees don’t ache after floor stretches anymore. It’s soft but still gives enough support that I don’t sink all the way through. Worth it if you spend time sitting on hard floors.

    Hazel ★★★★★

    I was skeptical 20mm would make much difference, but the couch-like sink-in effect is real and my joints thank me after long floor sessions. The memory foam layer stays perfectly in place once it's under the mat, no shifting or bunching at the edges.
