It is laid close to the ground and mainly plays the role of moisture-proof, protecting the floor, increasing elasticity and leveling the ground.

Too thick floor underlayment  have a lot of room for manoeuvre. Too much elasticity will crack the floor joints and even cause the tenons to break. If the floor mat is too thin, the effect of moisture-proof and cushioning is relatively weakened, the elasticity is poor, it cannot play the due leveling effect, and the foot feels bad.
