Selling a Lucid 5 inch gel memory foam mattress, size full XL: https://www.amazon.com/gp/product/B00NX8G712/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1&fbclid=IwAR29DVP3skXJ44Ap1Eu07ygB75Soxfb3iet8g4Vqv9St2fHdmaBQlTu4thY

I've had it for about 6 months and only selling it because I'm moving to a unit with a queen size bed. It's very comfortable and can be used either on top of the Stanford mattress or on its own. Always used with a thick waterproof mattress protector.

Asking 80$ OBO
