Zinus 9 Inch High Profile BiFold Box Spring / Folding Mattress Foundation / Strong Steel structure / No assembly required, Split Queen
Ordered it from Amazon in 2016: https://www.amazon.com/gp/product/B0077UCFXG/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
We rented an 1800s home with tiny doorways and could not fit our Queen box spring in the doors. These worked wonderfully! They were used for about a year, and have a few small tears, but are still usable.
