a big hit with all my cats . . first cat tree we ever had in which all levels would be occupied at the same time .  the larger sizes of the middle and top levels are great and easy to stretch out on.  Also the height and weight are perfect for one not so strong person to move; yet feels very solid and not wobbly; I liked that it comes in one piece!  Would recommend.  Arrived in perfect condition, packed just right and delivered on time
