We are replacing the carpet in our home. This includes steps and the kids rooms and playroom. We are looking for a carpet that is going to wear well on the steps (most important)and that will do well with stains. The stair case is very dated and will be replaced in the future (5-7 years) and want to make sure that we dont over buy on carpet since the staircase railing and treads will all be replaced with wood flooring once the kids are older (5-7 years). So with that in mind what would be the best product specs to look for in a carpet.... ptt vs nylon....frieze vs. short pile carpet and what density range would be appropriate for this application. We just want it too look nice for the 5-7 years so we are not having to rip up twice before we replace the steps permently. I think price wise we could go up to $25/syd Thanks for all your information!!!!
