I like Kettler swing sets, especially the deluxe collection. I wonder if they named it Deluxe due to it’s fine quality. For example, Strong, powder coated steel frame finished in primary vibrant colors. KETTLER® utilizes the highest carbon steel that will not bow with use. Special double coated polyester power coat finish that is warranted for 3 years against fading. Our number selling metal swing set by Kettler is built for safe play without compromise. The KETTLER® Swing set is recognized for its uncompromising quality & safety by the leading German Testing Institute. Four ground anchors firmly secure the swing into place. High impact resin seats with adjustable ropes ensure a perfect swing every time.
