Question: What is the frame made of?
Document: it does what it needs to dothe padding on the frame feels comfyand everything feels solidgreat buy
Seems well made and was easy to assemble.It is a bit compact for a larger guy, but overall does what it's supposed to.
It only took me about 15 minutes to put it together though. And there is no DVD since there seemed to be some confusion about this point.BUT...one of the screws was without the indent that you used to actually screw it (the groove that accepts the Phillips head) and one of the tapped holes in the metal frame was not tapped properly so the screw would not go in. I can't believe this level of crappy workmanship on such basic items.
I've seen the negative reviews about this product being made poorly and not coming with assembly screws; I was concerned at first but the roller did come in with screws and the metal and rubber parts are just fine. I gave it a four stars instead of 5 because there are no directions for assembly nor for doing exercises with this thing. (I previously owned a similar ab roller so knew how to put it together and how to use it - but for the novice, it might be a bit mysterious!)
that all i can said.i did not used it a lot but when i used it,i can feel it work............................
for the price and seeming durability this ab roller is going to do what I need but we'll see later if the thin tubing will hold
cant use it. bought it because it was adv as &#34;like new&#34;, when I received it all the hardware was missing along with the headrest. had to throw it away
Works Graat! Just had lower neck/upper back surgery on 11/07/13 & when my Doc let me off my leash to go back to the gym, sit-ups were KILLING ME! Nasty pain someone sugested one of these & it works great! Gives support where I need it & I'm still gettin the reps in now without the pain!
Wife was all excited to get this and when it came she couldn't put it together. The box was trashed and all the screws as well as the dvd are missing. She needed it for her trip tomorrow Tuesday 7/30.
What comes in the boxExercise DVDAb rollerHardware and screwdriverAssemblyAssembly was intuitive and it took 10-15" to get this together. Unfortunately, this item cannot be folded or disassembled easily for a more convenient storage, such as under a  bed.UseThe head/neck padding is comfortable. There are multiple hand stations for more flexibility. It helps eliminate neck strain when doing crunches. The construction is well designed and the setup is ergonomically sound.ConstructionThe padding is firm and is covered by vinyl.
