Me and my husband have a spring air mattress that is 17 years old and we need a new one. I don't sleep well during the night and have so many aches and pains. The problem is that we have been looking for 3 weeks and are so confused. We like the Simmons Beauty Rest but heard bad things about it. We looked at Sealy and it was like eeee. We looked at Serta, the Orginial Mattress Factory. We can't make up our mind. Guess after spending a lot of money on one we want it to last and be comfortable. Can anyone steer us to what we should buy? Since we had the spring air should we look at that? We are so confused! HELP!!!
