The single most horrible mattress ever made.

I bought this king sized mattress set originally in spring of 2007. It felt *great* in the showroom, and took a lot to convince me- as it was the most expensive one there. I believe in 'you get what you pay for', so I ponied up the $1500.00. It took 2 years for me to wake up in pain enough times to call the furniture store I purchased it from and complain. He acted as if he was doing us a favor, because he said Serta required there to be a 6" sag or impression for it to be covered under warranty. The mattress is only 9-10 inches thick to begin with.... Funny, but I just took the tags off to get the model # for this review, and Serta states 1 1/2" sag or impression..... If that is the case, we should be getting a new mattress every 6 months to a year from Serta, for the duration of the warranty, because it is well over a 1 1/2' hole I am/have been sleeping in. This time it has been 3 years, and waking up is a nightmare, and requires pain medicine to make it stop. Vera should have stuck to designing clothes, and Serta should have made a better mattress- Perfect Sleeper? More like a torture chamber with sheets.. This one is horrible. I would not recommend it to someone I hated.
