Hi dan87951,
If you only got 4 years out of a mattress then the most likely cause was lower quality materials in the comfort layers. While a one sided mattress that uses high quality materials in the comfort layers will normally last much longer than 4 years for the large majority of people whether you can flip it or not a two sided mattress will certainly increase durability no matter what materials are used.
I also agree with you that Buis Mattress is one of the good guys and makes great quality and value mattresses (which is why they are a manufacturing member of the site).
@ paisley …
If you do decide to look at Carolina Mattress Guild or step foot into Sleepys … I would make darn sure that you don’t buy anything on the same day you test mattresses no matter what you are offered and I would also make sure that you are able to find out the quality of every layer in a mattress before you buy it so you can make meaningful comparisons with other mattresses that have a similar design and materials. I personally wouldn’t walk through their front door. While a layer of latex is great … if its only a thin layer then the other materials are just as important and can be the weak link of the mattress. None of the links you posted have anywhere near the information you would need to make an informed buying decision.
I would also not pay much attention to reviews when it comes to evaluating a mattress (as you can see in post #13 here) because most people who write reviews have no idea of the quality of the mattress they purchased or what is in it (and the reviews certainly don’t include this information in almost every case).
You have many options for under $2000 and there are also many mattresses where the layers can be exchanged so if one layer no longer is suitable for you or if it softens or breaks down faster than the deeper layers in the mattress you can just replace a layer instead of a whole mattress (similar to the mattress topper idea except they are all inside a single cover)
When you are ready to buy a new mattress … post #1 here has all the basic information, steps, and guidelines you will need to make a great choice that is well inside your budget and also includes a link to some of the manufacturing members here that sell online and have some of the best quality and value in the country if you if you decide to go in that direction.
