DO NOT PURCHASE YOUR BED HERE!! We purchased a king sized mattress which was rated a 4 in firmness, we tried the mattress in store on a hard base, however we were not advised the mattress would not be compatible with the type of bed frame which had slats. This was because we were not told by staff that the firmness rating would change(which was important for medical reasons). My wife described sleeping on the bed as sleeping on a slant with the support only down the centre of the bed due to the frame work, however this was not advised that this would happen in store. We believe that we have been miss-sold this bed, and judging from reading the comments this is not the first time a bed has been miss-sold. We are also now struggling to get a refund and staff seem unhelpful across the phone to resolve the matter. As a result my husband has had drive down to the store to deal with the matter because the staff were too incapable to deal with it over the phone.
