I have this "narrow twin" mattress, which is 30 inches wide. I had to trim it in a couple of places to fit the back of my scion xb, which meant removing the cover. I got the version that is 6 inches deep, which is 5 inches of regular foam and an inch of memory foam. I ended up adding another layer of memory foam topper. I have always had my bed frame elevated a bit to allow air to circulate. At different times I have raised it as low as 2 inches (ie no under bed storage) and as high as 12 inches (too close to header). Currently about 7 inches I think, which is fine for me, and allows me to keep car tools and a few other things tucked under there. https://www.amazon.com/Zinus-Mattress-Fiberglass-Pressure-Certified/dp/B0CKYZRJXN?pd_rd_w=3qBIF&content-id=amzn1.sym.59fe5e4c-51b0-4912-8f07-69b7ad81293d&pf_rd_p=59fe5e4c-51b0-4912-8f07-69b7ad81293d&pf_rd_r=QEJPGPHFFEVD9RVTM2VC&pd_rd_wg=8tEu9&pd_rd_r=7feeb6be-d5eb-46ca-b373-7e835eb67e75&pd_rd_i=B0CKYZRJXN&psc=1&ref_=pd_basp_m_rpt_ba_s_3_sc
