Service and delivery were great.  Unfortunately,  the foot massage part of the bed does not work.  The bed was Very difficult to get into place so we will not be exchanging it for one that does work.  The rest of the functions work and I would have loved if all had worked.   We will see how long it lasts, hopefully other functions will  not go out..   It definitely does fit our California King sleep number bed so that's a Big Plus and we  were able to use our existing  sleigh bed frame which is another plus.
