This is one half of a split California king mattress. It's a Serta iComfort TemTouch Blue Touch 100 Gentle Firm mattress and it's in great condition. Selling because my wife needed something even firmer. I would call this medium firm while she needs extra-firm. I find it very comfortable which is why only she changed mattresses and I didn't.
No stains or anything, from a pet-free home. I think it's about 7 years old and hasn't been slept on in the last couple years. Includes the mattress protector which completely encloses the mattress. This is a memory foam mattress with a gel-infused top layer to help keep cool.
You will need to have a way to pick it up because we do not have a way to deliver it.
