I bought Zinus Sleep Master Ultima Comfort Memory Foam 12 Inch Mattress, Twin size on Amazon for $191. Bought it on July 6 2017 and barely used it for about 2 months. Reason for selling: Bought a queen bed.

The memory pillow (worth $29 and bought on July 6) was used only a couple times: https://www.amazon.com/gp/product/B01J0Q6N50/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

The IKEA bed is a year old: http://www.ikea.com/us/en/catalog/products/S59009824/. Currently dismantled, making it easier to move.

Should be picked up in person from Dana Street, Mountain View. Payment by cash/Venmo/Paypal only. CHEQUES will not be accepted. Price is negotiable!
