Integrating rounded corners into a table design can be challenging for several reasons:
Complexity of Design and Manufacturing: Traditional furniture manufacturing often involves straight edges, making the process for creating rounded corners more complex. Crafting rounded edges may require specialized tools and skills, which can increase production time and cost.
Material Limitations: Certain materials are more difficult to manipulate into curved shapes. For example, wood needs to be carefully bent or cut using specialized techniques, while metals might need specific machinery to achieve a clean and uniform curve.
Stability and Joint Construction: The junctions where the legs meet the tabletop can present structural challenges. Ensuring stability with rounded corners often requires meticulous engineering to maintain the strength and integrity of the table, especially since the natural run of grain or metal might be interrupted.
Aesthetic and Functional Balance: Designers must ensure that the rounded corners do not compromise the table’s usability. The curvature should enhance aesthetics while keeping practical considerations like space usage and stability in mind.
Customization and Consistency: When producing tables at scale, maintaining consistency in the curvature across multiple units can be demanding. Customizing designs for each unit might be necessary to meet quality and aesthetic standards, complicating mass production.

Overall, while the rounded corners might offer an appealing aesthetic and added safety by reducing sharp edges, their integration into a table’s design and construction requires careful consideration and additional resources.
