“These underlays are the best Ive tried. Definitely need someone to help put them down properly when theyre larger, especially placing the rug on top. Theyre tacky to touch but dont leave any residue on your hands or the floor. Ive put them under all the rugs in my house and they make such a difference. Worth the money as Ive nearly slipped in my nursery a few times before investing. Dont stand on them when putting down as theyll stick to your foot”
