i stumbled upon your post because im selling my twin XL foam mattress on Facebook. not sure if it's applicable, but i bought a Linenspa on Amazon and it was great. Im only selling mine because I chose the wrong firmness level. I went for a medium but should have gone for hard because of my back issues. otherwise it's a great mattress.
