I don't know much about sheets and stuff and I have always purchased the wrong sheets for my waterbed. Either they are too big or too small. I contacted this company and with a few questions they asked regarding my bed, they ordered for me some sheets. I was skeptical like when I always am when I buy sheets but when I got my stuff, I could not believe it. For the first time, I got the right sheets for my waterbed. I was always having such a hard time I considered getting rid of the thing. Well, I got my sheets and I was happy with the quality. Next time, I am going to try the higher thread counts. For waterbeds, they have these cool bands or something that keep the sheets in place. Pretty cool. I would recommend this company.
