Beautiful Twin Mattress

I am blown away by the size, quality, the feel, cute look, and comfort. I also appreciate the sale price. It definitely is not the twin size mattresses I grew up with 1957. It is so thick and cushy but thesheetsIboughtaren'tbigenough but that'sokayIwillbuytherightones. My Sister liked it so much too so I bought her one. The only downside is it didn't arrive as scheduled.
