I feel I was pressured, & I was not given a choice but instead they ordered what they said I needed. I now have 2 twin mattresses Called to see about exchanging for king matteress.FRED was supposed to check on and call me back, he claims to but I never got any call back. After I called Fred back he said it would cost me another$700. (after spending$5,000.) SINCE I AM NOT HAPPY WITH WHAT THEY SOLD ME I HAVE NO CHOICE BUT TO PAY SO I CAN SLEEP IN COMFORT. FRED told me he would put in order for new mattress yet a full month and I have heard nothing. Fred has not returned my call.
