One frame covers four jobs across the first two years: a bouncing saucer, an infant play mat, an activity table and a push walker for the wobbling stage. The saucer measures 32.5 by 32.5 inches and rises from 31.5 to 34.5 inches through three height levels, which keeps legs at the right angle instead of letting a baby stand on tiptoe. Three modes cover bouncing, fixed and sliding play. Around the rim sit a soft toy bar, a mirror, a monkey, a bird, a hippo, a telescope and a music box that runs on 2 AAA batteries, not included. Converted to a table the unit spans 40 by 23.5 inches, and the play mat lies out at 27.5 by 22 by 19 inches. Net weight is 14.5 lbs with a 25 lb limit under 30 inches tall.
