answer:I was mattress shopping before ********* last year. Here’s what I learned. 1) the cheap come-ons (mattress and sprint for $199) are total crap. Cheaply made and they fall apart. Anything to get you into the store, and then they try and upsell you. 2) Once you get up to the $400+ (per piece) you get into pretty high quality. That means – thicker, more springs, more padding, the works. But there’s not a huge difference between a $400 per piece and an $800 per piece. So don’t buy the expensive one just because. 3) More springs usually means a better mattress which will last longer. But the other factors are how springy they are (personal taste) an how they are attached to the frame. I do not remember all the details, but one way has a tendency to come out more quickly. 4) There is an actual technique to carrying a mattress. Have them deliver it – they know how to not stress the frame of the box spring (which makes it weaker) 5) Even though they say “30 days or money back” practically no one does this because of the hassle and inconvenience. 6) (Personal taste): Pillow tops are great. But it really depends on YOU and how high you want the mattress to be, and how hard it should be,
