Do NOT purchase Airloom does not stand behind there product

purchased Airloom bed in 2011 for 5K from Sit n' Sleep. 2015 it's sagging on one side. Went into Sit n' Sleep store and sales rep said we purchased a "spare bedroom bed". We were replacing our previous bed due to sagging, Sit n' Sleep honered the warranty and gave us a prorated credit. The sales person knew when we purchased the Airloom we were replacing a bed we were going to be sleeping in every night. We called Sit n' Sleep customer service and they sent a thrill party company out to inspect the Airloom. It was sagging 11/4" Sit n' Sleep would not honor the warranty, it had to be sagging 11/2" to fall u dear warranty. Jan. I asked to speak to a manager that I wanted to appeal and I am still waiting for a call back. Jan. I called and talked to Airloom and told them about our horrible experience with Sit n' Sleep and ansked if they would stand behind there product and honor credit. They said they would research my case with Sit n' Sleep and third party inspection and get back to me. It is Feb. and I have NOT heard back from Sit n' Sleep or Airloom.
