My old bladder sprung a leak as did the liner as well, after about 31 years of use!!! I bought my waterbed back in Auckland in September 1985!! The liner and regular bladder are semi transparent bronze in colour and have lasted extremely well having been moved several times ovr that 31 years! So after checking out our local furniture store (water conditioner only) and then online I found a shop called Bedworld in Christchurch (New Zealand) who sold the waterbed accessories... IE the bladders and liners for various size waterbeds. Mine is a Queen size and the bladder was made to order (tested 27/9/2016) but I think they had the liners in stock. I am really pleased with the service from both Bedworld and AquaPlus who made these. Now my waterbed is back to giving my back a great nights sleep. Produced with CyberLink PowerDirector 14
