At Seattle Mattress, we believe there is a “type” of mattress for everyone, and since there are so many people who still search for a double-sided mattress – we’ll still keep making them that way!

Our SMC brand mattresses are heavy-duty “workhorse” mattresses that often get more wear out of them than we originally give them credit for. It is a fairly common occurrence for us here at the store, to have previous customers come in with friends & family who are in the market for a new bed, and tell us that they are still on their original SMC mattress and that they still love it  – and the mattresses are often over 15-18 years old! Does a double-sided, flipable mattress give you more bang for your buck over time? It certainly can, especially if you are faithful and consistent in maintaining the mattress.

We suggest that you flip your double-sided SMC mattress once a month for the first 3 or 4 months that you have it – and then 4 times a year after that, making sure to rotate the mattress as well as flipping it every other time. This rotating and flipping of the mattress promotes more even wear in the comfort layers on the sleep surface.


The jury is still out regarding which type of mattress is better – the double-sided mattress you can flip or the single-sided one that you simply need to rotate.  All things being equal within a 10-year warranty mattress, both types are supposed to provide you with at least 10 years of a reliable sleep surface. And if they are properly maintained, either type of mattress can last as long as it should.

Generally speaking, double-sided mattresses have a top and bottom side that make either surface useable for sleeping on. The main benefit of a 2-sided mattress is to extend the life of the mattress. But people found them to be a hassle – they were a struggle for one person to flip, and most people ignored or forgot to follow the warranty directions – nullifying their warranties as the upholstery in the mattress would overly compress making the mattress uncomfortable and lumpy to sleep on.

By contrast, with regard to today’s single-sided mattresses - although the sleep surface is limited to one side, most mattress manufacturers are replacing “yesterday’s” cheaper foams and polyester fiber with more durable materials such as higher-quality open-celled foams, latex, and visco-elastic memory foam which do not tend to flatten or break down as quickly.

While these mattresses do not need to be flipped, they do need to be rotated on a regular basis – as often as once a month for a nice, cozy, thick pillowtop mattress. This is a very important step in maintaining a single-sided mattress that many salespeople neglect to inform their customers of when they purchase a bed. Foams need to be worn evenly in order to prevent “dips & valleys” from forming in the mattress since it is impossible to keep polyfoam from compressing. Another suggestion is to flip your single-sided mattress over when you go on vacation and let gravity help restore compacting foam while you're away.

It is very rare these days, that you will find a double-sided mattress manufactured by a corporate manufacturer such as Serta, Simmons or Sealy, etc. There is a story behind the reasons why…

Simmons Mattress Co. first introduced the one-sided, No-Flip Design around the year 2000 after deciding that they needed to get innovative again after having a semi-bad year in sales. (Simmons already had a reputation for being an innovative company after previously inventing the “King-size” bed and the “Individual Pocketed Coil” mattress).

Simmons claimed that their new mattress was not only an improvement, but was also a more maintenance free mattress compared to its 2-sided predecessors. Mattress manufacturers across the globe found the idea of a 1-sided mattress amusing, but doubted it would have much of an impact on consumers. As it turned out, Simmons ended up having an outstanding year in sales that year!

Suffice it to say, many other mattress manufacturers followed their lead with their own single-sided versions marketed with virtually maintenance free ad campaigns – and before long, almost every mattress manufacturer had single-sided mattress options available. As consumers continued to show more of an interest in single-sided mattresses, manufactures began to fade the double-sided ones out over time.

Though they had been consistently dwindling in availability, 2-sided mattresses were still fairly common up until 2007 when the Federal Government passed a safety law requiring all mattress sets built and imported into the United States to comply within a strict performance fire code standard.
