First Impressions
When I unboxed the STRAUSS Anti-Burst Rubber Stability Ball, I immediately noticed the premium, textured finish. It felt tough and resilient. Inflation took time (the included pump was small), but it held air perfectly for weeks.
The Boldfit Unisex PVC Stability Ball felt simpler but still solid. It was easier to inflate, lighter to carry, and less intimidating for a beginner. However, the surface felt slightly thinner.
Verdict: STRAUSS felt more professional; Boldfit was more beginner-friendly.
Durability & Build Quality
The STRAUSS ball survived repeated use—crunches, wall squats, backbends—without losing firmness. Its anti-burst rating felt reassuring, and the grippy texture prevented sliding.
The Boldfit ball did well for most moves, but over months, it softened slightly. On tiled floors, I noticed occasional slipping, though the anti-slip ridges helped a bit.
Verdict: STRAUSS wins for long-term durability and stability on varied surfaces.
