The Duro-Meds toilet seat cushions you manufacture are of very poor quality and seems like you have no intentions of fixing it. I have bought over 20 of these cushions and they are all the same. The foam you use is so cheap it breaks down loosing its thickness in no time at all. A 2 inch cushion becomes a 1 inch cushion and the 4 inch becomes less then 2 inches thick. Then the Center stitch starts to seperate and come apart. I have seen so many reviews who complain about the samething yet you do nothing about it because it sells more cushions. So I figure I've spent over $500.00 in cushions. The easiest thing for me to would be to have Amazon replace it once a month because that's about all they last. You would think a company of your caliber would sell a better product then this. User's recommendation: Memory foam would easily solve the problem and not use a cotton thread.
