Compared to Sleep Number functionability, theirs are almost on an equal scale BUT the exceptionally strong rubber odor lingers for more than 3 weeks after assembly. Not sure if this is healthy breathing this while asleep for that duration and longer if you keep the 2 twin bed set.
A piece from the whole package was send wrongly but the waiting time for the correct one was quick.
It seemed that there were not more than 2 customer service persons who are not thoroughly knowledgeable when an isolated problem comes up.
When told that we want to return the bed sets, they ask that we continue to try them as the month's trial was not fulfilled. WHAT! We were breathing in rubber fumes, was that not enough reason!
The return was a painstaking process of waiting of more than a month, continual calling to ask about the possible paperwork was annoying. Unbelievable!
I liked: Affordability and functionability.
I didn't like: Strong rubber fumes lingers for more than 3 weeks after assembly.
