Did you test it? A lot of people have issues with a lounge seat, the jets shoot them out of the longer.
People forget they become buoyant when in water and having 10 to 30 jets under you will be pushing you out of the lounger. What is a core fabric cover? Typically spas have a foam filled vinyl/PVC? cover, some are tapered 4 inches to 2 inches and some are tapered 6 inches to 4 inches. Biomagnet therapy? Ecopur mineral ... probably a mineral stick the "you don't need chlorine". Back in my first days of tub ownership there was Nature 2 and I think Bullfrog (not made by the spa company Bullfrog) or something like this. Stay away from these.
20 years ago Master was considered low end that charged a lot. Some dealers were excellent at taking care of their customers but Master did a lot of Spa shows and the dealers were getting screwed. Things may have changed over the years. I saw a few Master tubs back then that were very nice looking but the advice from people in the business on hot tub forums basically said stay away. I paid $6,200 for my spa back then so a spa 2x more in today's dollars could be a good value. I think a Sundance tub was like $2,500 more and Hot Springs was about $3,500. I don't know how much "better" brands are these days but there's more to owning a tub then therapy. Electricity is a major concern. Durability is another. Parts availabilty still another.
I'm not trying to sell you out of getting a spa but they are not all created equal.
