We have had this mattress and box spring set for one week.  This mattress is very comfortable and suits our needs.  However, the box spring is considerably higher than we expected making it somewhat difficult for children to climb into the bed.  My hope was to exchange the box spring for the low profile box spring that comes as an option when ordering.  However, after speaking with a Wayfair customer service representative, I was informed that I couldn’t make a simple exchange (the regular box spring for the low profile box spring).  Instead, I’d have to return the full set (mattress and box spring) and then purchase the set again - this time, specifying that I want the low profile box spring.  As well, I’d  have to pay about $200.00 for the return of my recently purchased mattress and box spring.
