"I have a 4 year old Serta split king Motion Perfect adjustable foundation with massage. The massage units are held against the underside of the adjustable deck with 4" square rubber gaskets. Three of the 4 have extensive cracks and one completely failed leaving the massage unit useless and hanging from its wire. I contacted Serta and they sent me to Ergomotion instead of handling the warranty themselves - Serta is on the documentation and warranty information, no where does it say Ergomotion. Ergomotion were ready to send me the 4 "free" replacement parts but told me I had to pay shipping & handling. They quoted me an "authorization charge" of $76.00. Their policy is to charge an excessive amount for shipping & handling then get 3 quotes and charge you the cheapest without consulting you. So it may be any charge up to $76.00 for something they could put in a USPS Priority Mail Envelope for $5.95. Odd how they can get a quote for $76.00 while I'm on the phone but can't get the other two quotes. Obviously, I decided not to be ripped off by a company that uses low quality parts and then profits from their warranty "service" with exorbitant shipping & handling. Serta should be handling my warranty, send my parts for free and deal with your suppliers yourself."
