I tried desperately to use this for 2 weeks before it finally hit the trash.  The plastic (CHEAP plastic, might I add) "stabilizers" do no such thing and fall off ALL THE TIME, terrifying my cats.  The "installation" is done with cheap velcro, so doesn't do the product any favors, and the platform fell down ALL THE TIME, further terrifying my cats.  Also, the perch and the plastic slats are 2 different colors (the shearling is off-white while the "stabilizers" are cream) so it's really an eye sore.  Go for the more expensive products, fully install, and DON'T buy this.
