I callec the store pricing a pillow top queen mattress. Spoke with a lady named Terry. She was pricing mr 7- 9 hundred at first. Asked her if they any cheaper ones. Right off the bat she was offended because I asked about cheaper ones. She said yes we have one for $259 and $459. Told her that was more around my price. Fixing to tell her I would be over today to purchase one and she Bluntly hung up on me! Then I called her back and told hdr I didn't appreciate being hung up on and treated that way!! Whats really odd is she tried to turn it around on me. They definitely lost a sale because or Terry's rudness!!!!

The sales gentleman wasnt pushy or anything, listened to what my husband and I both liked and our budget. I highly recommend them to anyone. I'll be telling everyone about them.
