Installation instruction is easy but, for me, executing it was a tad bit difficult. Because of the two wooden frames... You have to work hard to fit it in...I had to take out one side of the house again and put it back...Hope that in the next phase, they make the wood fit a bit nicely and smoothly. But that's a little flaw.
The house itself is surely very beautiful! The felt top is just luxurious and wonderful. I got the cream one...My cat slid right into it and other other cat is jealous and she now wants it :)
