Supra's Stackable Soft Foam Plyo Boxes combine a soft touch with rock-solid stability, making them the ideal tool for explosive workouts. Crafted from ultra-dense foam, they absorb impact to protect your shins and joints, while the added weight keeps the boxes remarkably tip-resistant—even during high-intensity exercises. Designed for durability, each box is wrapped in robust, heavy-duty vinyl so you can flip, drag, or push them around without worry.

Available in five sizes with a consistent 28x28-inch base, these plyo boxes offer versatile training options:

• 6" (9 lbs)
• 12" (16 lbs)
• 20" (28 lbs)
• 24" (36 lbs)

Stack them securely using the sturdy 10-inch Velcro flaps on all four sides. The wide base provides plenty of landing space, while the size is clearly printed on two sides for quick reference. Finished with cross-stitched handles in contrasting white and a neat, tuck-away zipper, Supra’s plyo boxes are as stylish as they are functional.
