We've had this ramp about a month now. It was easy to open and use , as you only have to install the side rails. This ramp has been perfect for a 27" high bed. Our 5 month old dachshund took to it very quickly. Even at 63" long, the angle is pretty steep at the tallest setting of 28". We were able to adjust it down to a few inches lower than the mattress and our puppy handles it great getting on and off the bed. No more worries of him jumping off the bed. We only use one side for the rails and I added a panel at the top to make sure he didn't try to go to far.but have since removed it after he learned how to go up and down. The ramp hasn't been moved since, so can't speak to how it would hold up with regular folding and moving around, but it seems to be built pretty good. Thanks Vevor for a great product.
