I've been sleeping on a 12 year old mattress and waking up every morning with a stiff back. Just one night on this Serta Perfect Sleeper Luminous Euro Top Queen Mattress and I had the best restful sleep in years. I don't think I even snored once. I woke up refreshed and pain free. It's just firm enough for me and the Euro Top adds to the comfort. As far as the White Glove Delivery. Top Notch. They called 30 minutes prior to delivery to let me know they were on their way. When they arrived one gentleman came to the door and greeted me while the other two gentlemen took my mattress and box spring off the truck. It was a drizzly day and the men asked if they should remove their shoes. WHO DOES THAT NOWADAYS?!? It was a pretty easy delivery for them as I just wanted them to drop the items off, there was no set up. They offered to remove the plastic and help me move furniture to get the mattress into the bedroom. I told them it wasn't necessary as I was going to build a new bed frame and was just storing the mattress until then. They thanked me and left. Excellent service.
