Some common mistakes to avoid include: 1. Prioritizing cost over quality: While it's essential to stay within your budget, investing in a high-quality table can provide long-term benefits in terms of durability, client satisfaction, and safety. 2. Overlooking adjustability and functionality: Choose a table with versatile features to cater to various treatments and client preferences. 3. Ignoring weight capacity and stability: Opt for a table with a higher weight capacity to ensure stability and safety during treatments. 4. Failing to consider available space: Select a table that fits comfortably within your treatment room, allowing for adequate maneuverability. 5. Neglecting care and maintenance: Proper maintenance is crucial for prolonging the lifespan of your spa table and maintaining a hygienic environment.
