Hi chrisw,
[quote]One would wish to buy a mattress that does it’s job consistently and be forgotten it is there altogether.
Guess I may have been overly impressed by their innovative design and commercials on durability test which was stated to be far more stringent than any other company. Have to assume that new products go through actual field test prior release to the consumer market.[/quote]
Unfortunately most field testing is more about whether a mattress will qualify for a warranty claim ( visible impressions that are deeper than the warranty exclusions and are regarded as “defects”) and not so much about the useful life of a mattress or how long it will take to lose its comfort and/or support and will need to be replaced (see post #174 here about mattress warranties). If there is an actual defect in the materials it will generally show up early in the life of a mattress which appears to be the case in your situation.
It’s always a good idea to make sure you know the quality/density of all the layers in a mattress before buying any mattress (see this article) and compare them to the guidelines here which will tell you much more about the durability and useful life of a mattress than the length of a mattress warranty.
You certainly chose a high quality and durable topper and you will have a much firmer and more resilient sleeping surface and “feel” than the memory foam in your Octaspring.
I hope you have the chance to share your feedback after you’ve received it and to let us know how it works out for you.
