Thanks for your enquiry about the latex topper. I really can't comment on the specifics of other products on the market but normally the cheaper the latex topper the more likely it is to have less pure latex and more filling agent (synthetic latex, clay or other material). Our latex overlays and pillows contain approximately 94-5% pure latex and the balance being synthetic latex which gives the overlay a consistent feel (stops lumpiness), gives product a better life span and a more comfortable feel.
