I got this bassinet for my wife and she extremely loves it. She's doing breastfeeding and always feel tired, especially has to feed my daughter every 2-3 hours. This bassinet is extremely useful and easy to assemble, took me about 20 minutes. It comes with the mattress. It has big pocket to store diapers, wipes and clothes. The height can be adjustable. Besides that, the front panel can be zipped down so that my wife can easily feed my daughter and sleep next to her but still ensure my daughter has her own space to sleep. 
With its modern design, the bassinet doesn't take a lot of space, but helps to save time and energy for a new mom.
