I have the similar issue to Denise below-the divan base top (cheap thin hardboard) is starting to sag. In a reply to my complaint that could have come straight out of an episode of Minder Bensons suggest this may be due to self assembly (I actually paid them to do it) or the euphemistically phrased usage patterns !!! (If only, but those days are behind me now) and suggest I might like to cough up £100 to have it inspected. (They absentmindedly forget to mention that bit before you buy). So be forewarned give these Arthur Daly types a wide berth and try your local bed shop instead. Wish I had.
