This gate was perfect for what I needed. Keeps my dogs from going downstairs. The height is good at about a foot and a half; easy to step over. I bought the large gate as the opening I needed it for was 47" and it more than covered the opening. I found putting it together to be a little challenging but once I got the parts in the right place, everything went together well. 
Highly recommend this gate! The price on Wayfair is amazing. I saved about $40 getting it through Wayfair. Walmart wanted $132.00 and other pet stores and websites even more than that! Plus Wayfair has free shipping!!
