Very disappointing

If you are in search of a new king size mattress this is NOT the place to go. I spend over $800 thinking I would be sleeping in a comfortable king size mattress that would at least last me 6 yrs instead it lasted me 6 months. Every morning my husband & i wake up with low back pain due to the BIG DENTS on the mattress. I called to explain the issue and I a got was excuses to not have mattress exchange. This is the reason why they say all sales are final and no exchange. I urge you to shop else where!!!!!
