We chose these stairs, since our new box spring with nearly one meter unfortunately is too high for our dog - when she fell from springing often from the back and jump down when she slipped while often arise from and towards much. So quickly had to be a staircase in order to avoid more serious accidents .. After this one had the best reviews and optics played a role, we decided for them. The staircase was delivered extremely fast (only 2 days from DE to AT) and was set up in under. It is actually very stable (even I can use it with my 55kg loose;)) and makes visually what her. It stands very straight, does not wobble and makes a high quality impression. Unfortunately, it is in our box spring (as I said 1 meter) to good 20 to 30 cm too low and a bit too narrow (our dog weighs 10 kg, making it one actually still on the small dogs). The walk up is already working fine (they must be on the top step of holding even a leap into the bed making) but when leaving the bed used it not, because it is just too low and in the darkness that's a problem. Nevertheless, a great product, and for that our bed is extremely high, the stairs can not help;)
