ADJUSTABLE PET STAIR RAMP
An adjustable stair ramp includes a pair of risers, a series of treads, and an adjustable support leg. Cross members extend between the two risers. Each cross member has a pivotal brace with a top edge. The adjustable support leg has a main leg portion pivotally coupled to the risers. The main leg portion has an upper portion and a lower portion pivotally coupled to the upper portion. Each tread has bottom surface with a first receiving groove and a second receiving groove configured to receive the top edge of the respective brace. Each tread is pivotally coupled to the risers for pivotal movement between a high step position, a low step position, and a ramp position. The stair ramp is reconfigurable for use as a high stair, a low stair, a high ramp, and a low ramp through the positioning of the support leg and the treads.
