This circular trampoline is approximately 100cm in diameter and is durable, with a steel frame and mesh material. - Color: Black - Shape: Circular - Diameter: Approximately 100cm - Materials: Steel frame and mesh material - Weight Capacity: 110 kg It's quite sturdy. It can be used not only for children's play but also for adult exercise. Please note that a cover and mat are recommended for use. They are sold separately. I do have a mat, and I can include it, but it's quite worn, so please don't expect too much. Please let me know if you'd like it. Thank you for looking.
