Hi gundeep11,
Unfortunately no … there are too many unknowns, variables, and personal preferences involved for me or anyone else to give any recommendations for any specific mattress for someone else that can possibly be more knowledgeable or helpful than the people that make the mattresses who will know more than anyone about the mattresses they make. If you were buying the mattress for yourself then your own careful and objective testing would be the most reliable way to choose a mattress (see mattress firmness/comfort levels in post #2 here).
I do think highly of Rick and the mattresses they make and they compete well with the best in the industry so they would almost certainly have a good quality/value choice that was suitable for your guests. If you can tell them your criteria and the parts of your personal value equation that are most important to you (including your budget) they will be able to help you make the best possible choice.
While I would certainly include them in my research if I was in reasonable driving distance, some of the other options or possibilities in the Orlando area (assuming that’s where you are) are listed in post #2 here.
