Selecting the material is the most critical decision for B2B buyers. EVA Foam is the most common choice for budget-friendly or beginner markets due to its lightweight nature and low cost, but you must ensure a high density (at least 45-50 Shore C hardness) to prevent deformation. Cork blocks are ideal for premium, eco-conscious brands as they offer superior grip, antimicrobial properties, and sustainability, though they are heavier. Wooden blocks (Bamboo or Pine) provide the highest durability and aesthetic appeal for professional studios but require smooth, rounded edges to ensure user safety.
