Are you still struggling to find a relaxing spot in your yard or lawn This swing set will definitely fulfill your imagination of a cozy and relaxing space In terms of structural design, it features a scientific A-shaped frame design with 3 side support rods firmly anchoring it, creating a secure "fortress" for the swing set. The thickened top pipe is even more powerful, significantly increasing its load-bearing capacity. This unique design concept fundamentally ensures the stability and long-term durability of the frame. (Please note: This is the swing set itself, not the swing itself.)Constructed of powder-coated steel, the swing set is not only rust-resistant but also incredibly durable. The top pipe is 1.58 in. thick, and the side pipes are 1.01 in. thick. This sturdy material allows the double hooks on both sides to withstand a static load of 550 lbs. Slight wobbling during use is normal, as we have conducted professional load-bearing tests to ensure it meets safety standards. The swing is thoughtfully designed with safety in mind, featuring 2 different mounting options: expansion bolts and ground stakes. Expansion bolts are an excellent choice for indoor installation, especially on concrete floors. For outdoor use, the 32 cm. ground stakes provide added stability, effectively protecting you and your family from all angles. Whether you're enjoying the afternoon sun in the garden or spending time with your family on the lawn, you can rest assured.
