Rarely used queen mattress with pillow top. Was in a guest bedroom, but we rarely have guests. It has been in the garage in a mattress bag for the past year. In great/new condition. Originally cost about $600 when purchased in 2019. Probably would be about $850 new with current prices.
There is also a metal bedframe that is tall, so no box spring is required. The metal bed frame is tall enough to fit large plastic storage bins underneath, so it was really great when we lived in a smaller apartment with less storage. Bed frame currently lists for $156.00. https://www.amazon.com/dp/B017YETJFG?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_3&th=1
