Don't buy from Serta!Serta is unethically advertising its Vera Wang "Sequins" mattress as being made with latex. Latex is the best quality material for mattresses and it usually comes in pads that are 2 inches to 3 inches thick. I would expect a lot of latex for a mattress that costs about 1400 dollars. However, the Serta Vera Wang "Sequins" mattress turns out to have less than half an inch of latex. They don't tell you that part when they sell it to you. The half-inch is there for legal reasons, but it serves no functional purpose. Besides being super thin, the latex is covered with several inches of artificial foam and quilting, so you can't feel the latex at all.
If you want a latex mattress, don't buy from Serta. Also make sure you get the specifics on every detail that you care about, because Serta as a company obviously doesn't have good ethics.
Additionally, the customer service person on the phone was the opposite of helpful, to the point of being unprofessional in arguing over the most inane points, and failing to email me a warranty packet that she twice promised she would send to me.
