Simmons Beautyrest Concord Plush,size, 167cm x 200 cm (65.7inches x 78.7 inches) is it king or queen? pls help

Question:Husband and I are in disagreement about the size, seeing as I always buy the wrong size sheets - checked web sites but no help, bought in USA, what do you guys think?

Answers:
It sounds like it's closest to the measurements of an "Olympic Queen" mattress. This is a new mattress size, 6" wider than a standard Queen, so it's not very common yet.

King Size Mattress 76" x 80"
Cal-King Size Mattress 72" x 84"
Olympic Queen Size Mattress 66" x 80"
Queen Size Mattress 60" x 80"

Your mattress is definitely not a standard queen, which may be why the sheets don't fit right. California King would be too long, King size would be too wide, and Queen would be too narrow. I don't believe I've ever seen sheets sold in this size in a department or discount store. Perhaps you can find them in a specialty linens store like Bed Bath & Beyond, as I found 5 items on their website. I did find lots of sites that sell them when I did a web search on "Olympic queen sheets."
