I want to talk a little bit about the VTech Sit-To-Stand Learning Walker because it's one of my grandson Jamie's favorite toys. The manufacturer says it's good for ages 9 months up to 3 years, and that does seem to be true. My grandson got his when he was 9 months old, and he's 21 months old now and he still plays with it at least once per day. There really aren't any other toys he's had for such a long time that he's still enjoying that much, so I'm definitely happy about that. And it isn't just him. Jamie has 2 cousins that are also in the 3 years and younger range, and when they come over to visit him, all of them want to play with the V-Tech Walker. What the kids really seem to like about it is all the different activities they can do besides just pushing it or pulling it around. This toy has a colorful activity panel that you can use on the walker, or take it off and put it on the floor so your kids can play with it separately. There are piano keys, spinning gears, sorting shapes, lighted buttons, a telephone, and recorded songs, sounds and sentences. The walker has 2 different modes that you can choose from so that it can grow with your child and give them new things to keep them interested. When Jamie was younger we set the walker to Music Mode and Jamie really loved hitting the piano keys and the buttons just to make noise. Now he still loves the piano, but we set it to Learning Mode so it can teach him numbers and colors and play animal sounds, not just piano notes. And he loves to spin the flowers for the sound effects and songs. His cousins also use the phone a lot, and there's more music, sounds and talking there for them to have fun with. The walker is very sturdy and you can adjust how easily the rear wheels spin so it won't skid out from under your child when they pull themselves up on it. There's also rubber on the rear tires to help prevent slipping. The walker does come disassembled, but the instructions are clear and I had no trouble putting it together myself. http://expressmobiledesign.com/walker
