I'd like to start by addressing your second question, regarding the relationship between warranty and longevity, as this is something that many mattress shoppers miss. The most important thing to know is that the length of a mattress warranty has nothing to do with how long the mattress will last. Some products with 25-year warranties will lose their comfort or support in 5 years or less. Likewise, a product with a 5-year warranty might serve you well for 10 years or more.

A warranty only protects you against manufacturer defects. Defects, like springs popping out or fabric not being stitched properly, are most likely to appear in the first year -- so in most cases it wouldn't really matter whether the warranty is 1 year or 100 years. Things like loss of comfort or support are generally not covered by the warranty, unless they reach truly extreme levels, which are most commonly defined as a 1.5" sag that can be assessed without anyone lying on the bed by stretching a string across the mattress and measuring the distance from the bottom of the sag to the string. Naturally, a mattress with a sag bigger than this is in pretty dire straits, and thus its condition is considered to be the result of an unexpected defect in the manufacturing process. The reason that nothing below this standard is covered is to make it clear that the amount of sagging and/or body impressions that can be expected under normal wear and tear is not considered a defect and thus is not covered at all under the warranty.

So, in terms of how long you can expect this mattress to last, our data suggests that on average, Perfect Sleeper owners tend to keep their mattress a little over 10 years before it needs replacement due to it being old or worn out. This is a typical length of time that is consistent with the average product longevity for all mattress brands.

Now, to address your first question about the warranty length of this specific model. According to the website of JCPenney, which is the only retailer that carries this model under the "Woodlyn Hills" name, this model has a 10-year limited warranty. The warranty information they provide seems to indicate that this is a pro-rated warranty, meaning the replacement value would be pro-rated based on the amount of time the mattress was used prior to a warranty claim being made.

Of course, you have surely noticed that in this case, the warranty length and the average length of ownership line up exactly, but it is nonetheless important to understand that this is merely a coincidence, not a causal relationship.
