My LO is 7 mos now. I have it downstairs. I used the bassinet for the 1st months. The changing table only until he was 5 months. I'm 5'4 and had to hunch over a lot also baby got taller and he would hit his heels on the metal bar so we stopped using it. Now he's rolling so I took the bassinet and changing table off to use the top part. The "mattress" is a thin material, looking to buy a mattress. Mine doesn't lock so every time I move it the bottom center pops up so I have to undo the top portion to access the bottom to pop it back down. I don't know if mine is defective or 1 of the couple of flaws.
