As a former dealer for Flexsteel, the quality has never been very good on them. At best they are a very average upholstery company. Cushion cores wear out over time and go soft. They actually are the second most costly component on any sofa after the cover. I'd opt for the $ 600 replacements, that is not out of line in todays' market and will refresh your sofa and give you another ten years out of it.

Only Hancock and Moore will unconditionally replace core cushions at no charge as a customer courtesy. All you have to do is pay the shipping which is fixed at around $ 100 for a sofa. That's a different category of sofa, however and will be double the cost of a new Flexsteel, but its the best upholstery maker in the marketplace.

Thank you for responding back. I appreciate the insight into Flexsteel.
