Queen Serta Perfect Sleeper Mattress, Innerspring, Pillowtop (Sherman Oaks)

Giving away this Queen Serta Perfect Sleeper mattress (innerspring with pillowtop) since replacing it with a new mattress.
As far as I can tell, it's in good condition.
The pillowtop isn't as pillowy as it once was.
No stains as far as I can tell.
No holes or tears, just some barely noticeable fabric imperfections.
I can't precisely place its age but I would estimate that it's about 15 years old.
However, throughout the vast majority of it's life it hasn't been slept on by anyone weighing more than 140 lbs.
I think the comfort level is somewhere between medium and firm.
No other details available as I can't find any literature on it online.
Pick-up required.
