Question: What material is the foam roller made of? Does it have a center core in the middle or just all foam? Thanks!
Document: This is not a quality product. The roller is not dense at all. This foam roller is made from two pieces of foam; a foam core and an outer layer. The problem with the roller I received is that there was a gap between the foam core and the outer layer of foam. What happened then is when you lay on the roller it immediately sort of flattens out making it more of an oval shape than a round roller.
Its an OK foam roller, middle is starting to give already and its been a month. It meets basic expectations but isn't what i would call &#34;premium&#34;.
The picture was too tiny to make out the material of this foam roller. I was hoping for density similar to disposable coolers or bike helmets but it turned out to be more porous and fluffy, definitely NOT &#34;extra firm&#34;.
I bought this foam roller back in May do to the cheap price and decent reviews. Unfortunately for me, by August it was starting to breakdown and by October the core actually became separated. It's now in two pieces and extremely broken down. I don't recommend buying this if you use a foam roller every day. Spend your money on something more high quality.
This foam roller is sturdy enough to support  my 210lb body yet not so firm to make the rolling uncomfortable. After less than 5min rolling out my back and legs, I feel like a bowl of jelly on the floor...such lovely relaxation. I will be incorporating the roller into core work in the future, but for now its sole purpose is to help roll the tension out of my wound up muscles.
This foam roller is very sturdy and well made. It is VERY firm. You an find youtube videos showing lots of different ways to use it to benefit practically your entire body. It is great for getting out the aches and pains, relieving tension and breaking up knots. Highly recommend this roller.
Low price and works great. I'm a big boy 240 lbs and supports me fairly well. It also has good length. Would recommend to anyone wanting a larger foam roller. Also I'm in CA, it got delivered very next day. Made my muscles happy.
Do not be mislead by the &#34;firm&#34; in product description. This is nothing more than a thicker &#34;noodle&#34; you would find in the pool. The foam is of extremely low quality. A small amount of finger pressure on the sides leaves permanent indentations in the material. Also, the roller arrived significantly bowed. I can't confirm if this was as a result of shipping or how it was shipped.
This roller works but it is not nearly firm enough. I am sure that after a few more months of use it will be worn out. The material is just poorly packed and has lots of air space.
This is not the hard one from class! It is slightly better than the white one from class but it breaks down fast and can no longer use it really. it's mushy in the middle now. Don't buy this if you want the hard roller. Its not hard and is soft in the middle after less than a dozen uses. I'm bummed but didn't pay much for it so it was good while it lasted, just wished it lasted longer.
Answer: yes
