I have one like that from Joanne's. Mine has the shelves also. I find it very sturdy as a cutting table but definitely NOT for sewing. It is not rock solid and does have some movement when shaken. I chose it because I have limited space and am very pleased with it. I usually keep one extension Open for cutting, but on occasion open both extensions for laying out a quilt. It is very easy to fold down both extensions and move the table--even into another room. It is very versatile and portable. If that is what you are looking for, you will probably be very pleased with it. I do think the price is high. I got mine on sale at Joanne.com for about $160 with FREE SHIPPING.
