Crafted with little hands in mind, PlayStar's gym rings boast a larger grip area for a comfortable and secure hold, encouraging kids to soar to new heights of imagination and adventure. Built to withstand the most spirited play, these rings are constructed from high-density polyethylene (HDPE), guaranteeing they'll never crack, break, or fade over time. Safety and durability are top priorities, which is why each set includes not one, but two gym rings, paired with two heavy-duty welded link chains, all thoughtfully coated with a soft rubber finish for added protection and peace of mind. Please note, swing hangers are sold separately. Backed by a solid 10-year warranty.
