As a former employee of Restonic matress I can say that all your complaints are valid. I have witnessed the the short cuts.
Using soft foam as a substitute for firm foam due to the fact that we consistently ran out. As for the warranty...they never keep their word.
I once watched a 90 year old couple come in to place an order and see how things were made. The owner was laughing behind their back saying "watch I will give them a free lifetime warranty if they by because they will be dead soon anyway.
