I'm in a quandary. My wife and I plopped down a chunk of change early in 2015 for a new mattress that we both believed would deliver to us endless night of relaxing sleep. That has not worked out like we thought. We chose a Serta memory foam mattress from Ashley Furniture that was med-firm. She sleeps great but I, on the other hand, wake up about twice a week with headaches and backaches. I can honestly say that I've had less than 20 good nights of sleep since we bought it. I'm leaning hard on going back to a spring mattress but was curious: What kind of mattress do you like and what do you like about it?
