Having bought a merino wool sleep system in Spain a number of years ago I knew the benefits of sleeping under wool having now switched to twin beds I found a polyester and feather quilt both made me sweat our old wool blanket is a super king size so was not practical so that is now left to our visitors so without a trip to Spain to purchase a single size system which would be more expensive I decided to purchase from the wool room first class delivery service and the best night sleep for a very long time without waking up wet thankyou once again Terry H Calne Wiltshire
