Let me start by saying this mat surprised me. At $30, I expected something basic, but the HEDUGO mat outperforms my old $50 yoga mat in cushioning and comfort. The 6mm thickness is perfect - it protects my knees during ab roller sessions without feeling too squishy for yoga poses.

The built-in guidelines are genius! They're subtle indentations (not annoying printed lines) that actually help keep my ab roller movements straight. No more wobbling side to side mid-rep. And unlike some mats, there's zero chemical smell right out of the package - big win for home workouts.

Now the anti-slip claim needs context: On my hardwood floors? Rock solid. But like one reviewer mentioned, it does slide slightly on carpet during intense ab roller pushes. The TPE material grips hard surfaces beautifully though - no adjusting mid-workout on tile or wood.

Cleaning is a breeze - just a quick wipe with a damp cloth after sweaty sessions. The waterproof surface hasn't stained despite regular use. At 72" long, it fits my tall frame better than standard yoga mats during full-body stretches.

Minor gripe? I wish it came in more colors. The plain black shows every lint and hair (my cat loves "helping" with workouts). But for joint protection during HIIT, Pilates, and especially ab roller routines, this mat delivers serious value. Just know your floor type matters for that anti-slip performance.
