This chair has been really helpful around the house. My daughter loved it for the first couple weeks of life, and then she went through a phase where she didn't want to be put down if she was awake. It was impossible to get anything done. BUT, this chair was still helpful then. This chair was the only way I could get a shower and get ready some days. Thankfully, she likes the chair again, she loves it on vibrate. And she always looks very comfortable in it. The chair was easy to put together, and is sturdy. The material is super soft, and I like how the piece she lays on is easily removable to clean if we have an accident. The vibrator in it has two settings, a low and high. My daughter loves the high. She screams and cries and the second I turn it on, she calms down and looks at me with a relaxed face. I am very happy with this chair. Update: My daughter is almost 2 years old now so I am not using this anymore. But when she was about 18 months, she liked sitting in it once in awhile. It held up well, I worried that she was too big and would break it, but that thing is sturdy. Versatility There's not much versatility for this. I mean, its a chair. My daughter just sat it in. I guess if she slept well in it, I would have put her in it for some naps, but she wasn't good with naps unless she was cuddled with me. Durability Holds up very well. My 23 pound, 18 month old would sit in it every once in awhile, and it held up well. So, I would say it is very durable. Ease of Use Buckled easy, the buttons worked well. Easy to use overall Safety As long as my little one was strapped in and buckled, it was very safe. As a newborn, I didn't bother buckling it most times, cause she didn't move and I was always right next to her. Features The vibrate worked well, the music was nice and not too loud. The seat adjusted up and down pretty easy. The fabric is soft and my daughter always seemed to enjoy sitting in it.
