Hi dneal,
Welcome to the Mattress Forum! 
The specifications for both the Love & Sleep Mattress and the Best Mattress Ever are listed here in the Simplified Choice Thread. Both of these mattress use more durable materials than the Leesa. Both Brooklyn Bedding and SleepEZ are site members here, which does mean that I think highly of them.
While I can’t tell what mattress might be the “best fit” for you, you should always make sure that you find out the information listed here so you can compare the quality of the materials and components 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.
