Years ago I hacked off a euro top mattress topper of my son’s old twin bed and I kept it wrapped in an old sheet for an orthopaedic base for my aging border collie. I was looking for ratings of dog beds and came across the NYT Wirecutter review and saw Molly Beds. I loved idea of a new cover for old textiles and ordered the X-Large and large cover. The two covers fit the euro top perfectly and I am now the proud owner of two beautiful dog beds; one for my Border and one for my new pup. I am in Canada and the delivery was smooth and fast. Love you Molly Mutt!
