I'd had my last sofas from Dfs and had no problems, they must have been around 15 yrs old. I decided to buy new ones and was so pleased with the Marlo sofa and chair when they arrived. Love the colour and style. I began to notice though that they just weren't comfy to sit on. It seemed that the back of the seat was overstuffed and I just kept sliding forward leaving a gap at my back. I tried a cushion at my back but still kept sliding forward. One friend placed a cushion under her legs behind her knees to keep her from sliding forward! I now have a back ache which I'm convinced has been caused by the sofa. I contacted Dfs who sent an upholsterer to check it out. He told me there's nothing he can do and it's just the design. I will contact them again but don't hold out much hope after reading reviews on here. I'm thinking of now buying a footstool of the same height as sofa to see if that solves the problem any.
