I initially bought a medium
"I initially bought a medium Queen size Spartan roughly 5 years ago. The mattress, be it the springs or the foam degraded to a degree that it began to give me back extreme pain. I contacted the warranty department and they sent me a completely new mattress. I switched to a firm this time. Great warranty and customer support. Brooklyn stand by their products. I recommend choosing a slightly firmer mattress, the base Spartan runs softer than typical mattresses IMHO."
