From Cathy -
Hello, I am looking for a cal-king mattress for my RV. the mattress size is 70×80. I could probably get by with a 72×80 or 72×78. as long as the mattress is not wider than 72 inches. the length is important due to the slide out in my Rv. the mattress cannot be longer than 80 if it were shorter by an inch or so that would be fine. i am looking for a a comfort range of 7.5 or 8 ish. i do like pillow top or europe top. i cannot have a box spring. the bed is designed for a mattress only. could u please give me some quotes on what a custom mattress would cost. if u have regular cal-king mattress like a 72x 82 that would be okay. i just have to watch the width on the mattress the length can give a little by a couple of inches. I live in Washington state. I would need it delivered. I hope i have given enough info for some prices or suggestions. the regular RV mattress are thin and horrible. We live in our 5th wheel RV full time so we could use a great mattress.
