Blue color- We offer this popular base for customers that prefer blue to our standard black rebounder. Contrasting edge banding-To aid in centering on the rebounder, Needak utilizes a space between the jump mat and spring cover. This visual cue tells you when you are near the edge of the jump mat. We have added a platinum band to make this more obvious when doing vigorous exercise. Improved jump mat-all of the Needak rebounders use our new mat cleat and newly upgraded sewing pattern to produce the best jump mat you will find anywhere. (optional frame skirt not included)
