My apartment complex is replacing my carpeting with vinyl sheet flooring. This is fine with me, except for the fact that apparently I will have to replace all my rugs because they're either rubber-backed -- which can react with the vinyl and stain it -- or they have scratchy underside material that can scuff and dull the finish. That leaves vinyl-backed rugs or woven, reversible rugs -- but the woven rugs apparently have to be colorfast, a quality that NONE of the rugs I've found seems to list on the label.... (AND since I'm on a teeny-tiny budget my options are limited anyway. It's still worth it to have rugs, if only to prevent dirt from grinding into the flooring.) Also, do I need to put something under the casters on my furniture (several items have them) even if these items are going to stay put at all times? I welcome any advice from vinyl sheet flooring owners who can help me figure my way through this.
