Love that they were ready to use when they arrived all assembled. We have a doberman and a mastiff. Bought these to section off an area in house to keep them from running though when they come in from outside as well as separate them from grandkids. They work great, look great and the height is perfect for our tall dogs and they are not tipsy at all. Also love how easy they fold up for storage and the fact they don't have to attach to a wall to use. I bought two set and may buy 2more for basement. Very pleased with them!
