Have a 6 months old Sealy Queen Sized Summer Grove mattress that I bought from mattress discounters in Menlo Park. Mattress is in almost new condition and has always been used with a mattress cover. Mattress is great for the back (beats any IKEA mattress) and comes with a 5 year warranty. Selling mattress because I'm leaving the country in 1 month.

Also have queen bed frame for sale at $70 if interested (also 6 months old) in great condition
