Pure Opulence Mattress. We bought the same mattress as Wayne Green six months ago. and agrees with everything he has said in his review. The salesman in Oxford listened to what we wanted and assured us that the 'Opulence' mattress would be perfect and would give us a good nights sleep for 'several years'. After a few days the mattress was also sinking where we had slept. Six months later it is even worse and looks much older than the 10 year old mattress that we gave away before buying this one. My husband said we should contact Bensons to complain but have decided we would get nowhere on doing so after I spoke to an old friend who has also had the same problem and has got nowhere with Bensons customer service apart them sending a so called expert to examine the mattress, again the verdict was blamed on misuse of mattress! My advice to anyone thinking a mattress from Bensons Bedss is DON'T. It seems you will not get anywhere if you complain. Maybe all unsatisfied customers should get together and seek legal advice!
