Cannot recommend this duvet more highly. I have only ever had feather duvets until now and I am totally converted to a wool duvet. Our bedroom in the winter is so cold and I was continually waking in the night due to this. Since I purchased the All season deluxe wool duvet I have had brilliant sleep and not woken once from being cold. My husband feels the same. We also purchased the mattress protector and again it is cosy and our body temperatures seem to be better regulated. Just brilliant. Price wise too I really think this is a bargain. Have already been recommending to friends. I ordered both the duvet and protector and they came within 24 hours.
