Hi droidx.
You can read a recent unbiased expert opionon and snapshot of Tulo mattress written by one of our of our Trusted Member experts ~ Jeff from Mattress to Go, and keep in mind that a mattress is only as good as the quality of the materials inside it and only as good as how suitable in terms of comfort/support that particular mattress is to you.
The weakest link in the Tulo mattress you are considering would be the memory foam in uppermost layer with a density of 3.25lb … which would undergo the most mechanical stress and would be the first one to break down. Generally, for each mattress, you are considering make sure to compare the exact specifications (such as foam density) information listed here to the durability guidelines here to make sure there are no lower quality materials or weak links in a mattress that would be a cause for concern relative to the durability and useful life of a mattress before making any purchase.
As far as the price goes, you are the only one to assess the worth and the tradeoffs between quality and price and all the other parts of your personal value equation that are most important to you (including the price of course and the options you have available after a purchase if your choice doesn’t turn out as well as you hoped for).
