Overview
39 inch rebounder trampoline built for JumpSport models 220, 230 and 250, with a steel frame, 30 low-impact EnduroLast bungee cords and a padded lay-flat mat, backed by a lifetime frame warranty.
Bungee cords rather than metal springs give this rebounder its stated low-impact, quiet bounce, an intentional design choice for joints over a harsher spring-based mat. The arched-leg base is patented for stability, and the purchase includes 60 days of access to JumpSport's streamed workout classes. The listing text elsewhere mentions a 33 inch skirt option, which is a separate size variant from the 39 inch model specified in the title.
- 39 inch steel frame with arched legs
- 30 EnduroLast bungee cords
- Lay-flat padded petal mat design
- Lifetime frame warranty plus 60 days of streamed classes
Who it's for
Suits home users wanting low-impact cardio in a compact footprint, especially those sensitive to joint impact from running or jumping on harder surfaces. Less suited to anyone wanting a large outdoor trampoline for higher jumps, since this is a compact indoor-scale rebounder.
Strengths and trade-offs
Drawn from this product's published specifications.
- Bungee-cord EnduroLast cords for a quieter, cushioned bounce
- Reinforced lay-flat padded mat extends usable space
- Steel frame backed by a lifetime warranty
- 60 days of included JumpSport Fitness TV classes
- Compact 39 inch size limits jump height compared to larger trampolines

Performance notes
EnduroLast elastic bungee cords replace metal springs to cushion each landing and keep the bounce quiet, while the reinforced lay-flat mat extends usable jumping space beyond the frame edge. Patented arched legs are the stated source of stability when stepping on and off the platform.
