Detachable legs mean this keyboard works two ways: bolted to its stand with the stool in front for an older child, or lifted off and set flat on the floor for a toddler who cannot reach a seat yet. The 16-by-6.5-inch keyboard carries 37 keys, 22 demo songs, 4 instrument tones and 4 accompaniments, plus playing and recording functions and 15 volume steps. An adjustable microphone bends to whatever height a child is sitting at, and a detachable music stand of 7.5 by 4.5 inches holds a page open. Legroom under the keyboard measures 11.5 inches and the stool seat is 8 inches across, rated to 110 pounds. The whole set stands 17.9 inches tall and weighs 3.3 pounds.
