Do not buy Nectar ever! The mattress sunk on the sides by 3 inches, only 2 years after buying it and after multiple rotations of the mattress. Upon sending them an email as proof of my mattress, and a request to have my existing mattress exchanged with a Nectar hybrid, and not foam, I was told that this was not policy and that it would not be possible to exchange the mattress for another model even though I offered to pay the difference. Poor quality control on your end and obnoxious exchange policy should not affect customers with severe sciatica issues. I am one very unhappy and dissatisfied customer! How do you expect me to buy the same mattress that has sunk only in 2 years, AGAIN?! How ridiculous if that don't you think? I will never buy from Nectar again and I will spread the word in the community as well.
