Wayfair, my back and I thank you.  Even though set up is a two person operation, I managed to do it by myself with relative ease.  I decided on a firm mattress and have not been disappointed as I sleep pain-free through the night!  Had a couple of questions for customer service and they responded quickly with all the right answers.  Adjustable bed works great with all the adjustable settings very convenient.   Strongly suggest this model...right bed for me at the right price!
