A 55cm massage yoga ball (also called a stability, gym, or sensory ball) is a versatile fitness and therapy tool covered with tiny particles or spiked textures.

Key Features & Benefits

Size: 55cm in diameter, best suited for individuals with a height of roughly 150 cm to 160 cm (4'11" to 5'3").
Textured / Spiked Surface: Provides tactile sensory stimulation and a light massage effect to help relieve muscle tension, improve blood circulation, and ease lower back or shoulder aches.
Anti-Burst Material: Made from durable, non-toxic PVC designed to deflate slowly if punctured rather than popping suddenly.
Multi-Functional Use: Great for yoga, Pilates, core strengthening, physical therapy, balance training, and pregnancy or birthing exercises.
