Megan has arthritis in her knee (following an operation she had 2 years ago). While researching this we established that laminate floor (which we had in every room downstairs) was the worse thing for her. So, last week we had carpet fitted in the lounge and the difference in Megan was noticeable from the start. She seems a lot more confident on her feet and doesn't struggle to get up like she used to. Well worth it!
