I got the 6 foot tree and fit perfect for an apartment. Be away 6 foot means including the stand and the long top piece that the angel or star sits on. It fluffed out well but will need to vacuum before and after assembly.

Ex Output:
positive

Ex Input:
I am a senior and don't get the exercise I know I need. This has helped me so much with the circulation in my legs and given me muscle that I haven't had in years. I love it because I can sit in front of the tv or while on my computer. I usually use about 30 min every time and I love it.

Ex Output:
positive

Ex Input:
Product covers were too difficult to take off. The 1st cover took to long and dust was able to settle on the sticky side and the clean screen. The second cover took off the screen protector. I had the wrestle with it and some dirt got under the protector. Edges are peeling up after a few hours. Works fine for touch but not an easy install.

Ex Output:
negative
