We were missold the bed despite our stated requirements. The cocky salesman managed to convince me that black was white. The delivery men knocked down our wall with the van and tramped mud up our pale stair carpet. Never did get resoution on that. Four years later, both of us are in agony. The mattress has unwarranted dips which Benson's claim are allowed to be 60mm. Their tame inspector from Homeserve completely misquoted the issues in his report and completely ignored the fact that the stitching was also coming apart underneath. Customer service rating is zero, the option below doesn't work for that.
