I got married last October. One of the first purchases we made as a couple was a bed.
Believe me when I tell you I researched everything there was to know about our possible choices. In the end I found that each maker and model had just as many complaints as compliments. Even the beds that were 'perfect' and lasted forever like the most expensive $4k Tempurpedic was met with complaints about being too pricey.
We tried out several beds, and decided we wanted the $3,000 Tempurpedic but we couldn't afford it at this time. We planned on buying a Restonic bed (Ashley furniture) but we were met with mixed reviews from different salesmen at different locations (sometimes the same location). Bottom line, every salesman had a pitch - and they were all different. Every mattress was on sale, and every mattress was in limited quantity. This went on for a couple months.
Our heads were spinning and about to explode, so we finally went shopping on Black Friday with the intention of buying a bed. We went to Comfort King where the guy told us that the mattresses were made on location and fed us a speel for 30 minutes; we went to Furniture Mart, Discount Beds, Ashley, Sears, Karl's, etc etc etc. We finally ended up back where we started at Ashley's and got a sleazeball salesman (not the guy we dealt with before). We asked him to leave us alone but he gave us one last opinion on what he would buy. We looked around and finally laid on a bed that we both liked. We jumped on it quick before we changed our minds. Of course it was the only one in stock (imagine that!). It was a good decision. All beds fail, all beds eventually wear out. People are going to complain no matter what, and people are going to praise no matter what.
So we ended up with the "top tier" Sealy PosturePedic pillowtop for $699. 'Normal' price was $1,599. WE enjoy it. The bed is comfy and hasn't developed any defects after almost a year of ownership. Trust me when I tell you that everyone's got an opinion and they're apt to share it with you. I took my parents' advice and went with this bed, we are not sorry.
In the end it's what works best for you. Lay on a bed and if it fits, buy it. Because if you go looking for reviews you will be discouraged out of that bed and encouraged to get a different bed, only to find out that bed 'sucks' too. And mattress salesmen are worse than car salesmen. Except with cars you know what model you're getting - with mattresses the models change names every 6 months. The model we got was called the 'Credo', but that doesn't matter because it goes under a different alias now. Like a criminal!
Fair warning!
