All of the tutorial information aside, PPP’s and such.
I have found Engineered Sleep to be transparent, patient engaging and an overall great experience to converse with. I have “tested” their chat site out, spoken with a representative there on multiple occasions and they have been nothing but accommodating, informative and cordial. Their variety of product available including Wyoming and other oversized mattresses systems to be quite convenient for those who need it. Their reviews are impressive as well of those who have purchased from their product line.
Beyond that, I suppose the only way to know for sure is to try them out.
