Happi jac upgraded mattress

We will be getting our first TH soon. The Happi jac system seems to have a large bed, but the mattress in the ones I have seen appears low end.
I have a buissiness nearby that custom makes mattresses.

My question is can a really thick mattress be put on the Happi jac system. Can the upper stop mechanisim be adjusted or modified to account for this? If so, how?

TIA

We fulltime and that's the fulltime beds for the kids. We built out the upper bed into a pair of twin size mattresses that run with the length of the trailer. We went to a mattress store and looked for the shortest decent twin size mattresses for the kids.

We didn't change anything with the Happijac system except for taking the lower benches out.

Yes, you can lower the upper stop, there are adjustments. We put a topper on our bottom bunk, helped a lot. The upper was a futon on ours, didn't get any complaints.
