This thing is not a chair you can't sit on it comfortably. The product image and actual product is absolutely 2 different items. It is kind of impossible to sit on this and lean back since there is nothing to lean on. I carefully read the instructions rolled it over on the floor about 10 minutes and waited almost 2 weeks to see if it goes to full extend but it is just a big useless thing sitting on my 3 years old bedroom. I am not sure if I received a defective product or this is how it suppose to look like but definitely nothing like the product picture shown.
