I have owned a Select Comfort mattress since 2003 and am very pleased. Not “Junk” in my book.
I had a Select Comfort Sleep number mattress. It was OK as far a comfort went, but it was too light in terms of weight and it floated about on the bed and that was a pretty big negative for me. Sold it and bought one of those Tempur-pedic and have been thrilled by it ever since. Much more comfortable and it doesn’t float, and it takes regular King sheets. The Select Comfort had an odd size that was just under the standard King size bed and the sheets didn’t fit right either. Seemed like it was designed to fit into a waterbed frame.
