We replaced our 20 year old wall to wall carpet with the Plush Removable Carpet Planks. Under the older carpet was OSB subflooring. Planks were easy to lay out and easy to cut - for a wall to wall result. While not entirely seamless, the seams are disappearing a little over time and with vacuuming. We are very happy with the results. Also applied over tile flooring in the bathroom (not sure this is an "approved" use). Were able to cut a curved line around the toilet to fit exactly. Best part was we could do it ourselves (60 yrs old & 73 years old). Didn't have to remove furniture from the room, just moved it around the work area. We have a 15 year old female dog that leaks occasionally; happy we have the choice to clean and/or replace planks! Love the feel against my bare feet and once installed no shedding.
