I purchased the split king which is 2 twin xl bases to make the king bed. I would love these if the measurements shown were correct and the cheap plastic legs weren’t so flimsy!!!! 

It shows that the height from bottom of base to floor is almost 15” but with the legs extended to their full height the measurement from the bottom to the floor is only 11”. I bought these because I needed the height so I’m very disappointed and they are so heavy it would be impossible for me to return them now. 

The bases are on vinyl plank flooring and they move constantly, wobble and my husband said he feels like it’s constantly going to fall over. They creak and make noise every time we move as well. Now I’m going to have to spend more money trying to come up with a solution!!
