I just bought this afew days ago and Set it up just the way it was suppose to bet set up on the manuel. Its great on my hands and knees and really feels smooth but not too soft but! Only weird thing i noticed is that it is a weird shape! Its almost Lopsided in certain areas. I dont know if its because it needs to be broke in or if its because the padding has been boxed in and still kept the box shape? Anyway its 80 pounds and here are some pictures let me know what you think.
