Hi Elderblaze,
Just for the sake of clarity … SleepEZ has either a 9" mattress that has 8" of latex or a 10" mattress that has 9" of latex.
This would depend on the parts of each person’s personal value equation that are most important to them which may include delivery times, any bonuses that come with the mattress, the options that are available to customize the mattress after a purchase by either rearranging or exchanging layers and the costs involved for any layer exchange if that becomes necessary, the specifics of the return policy and the costs involved, and any of the other objective, subjective, or intangible factors that are involved with a mattress purchase that may be important to each person.
