Worst Mattress I Have Ever Owned!

This mattress was literallt the WORST mattress that I have ever purchased. When I initially layed on it in the store, it felt comfortable; however, it took only one night of sleeping in it to prove otherwise. After 20 minutes or so, the entire memory foam/memory gel, top half of the mattress simply sagged beneath you leaving you with no support whatsoever. After several trips to the chiropractor in the first week I even went so far as to have a friend lay on it. She concurred with my opinion...she thought it was awful. I went back to the store which, thankfully, had an exchange policy and replaced it. My new mattress was going to take several days for delivery...the Valencia was so bad that I actually opted to sleep on a very old mattress in my guest room rather than to sleep on it during the wait time for the new bed! I was really upset because this was hardly an inexpensive purchase. I am now writing this review as I lay happily in my new Tempurpedic. I will NEVER buy another mattress from Kingsdown. Save your money.
