Is a bed frame even needed if I have an adjustable base?

This is an old post so I imagine this has long since been resolved for the OP, but since I just saw it, figured I'd throw our experience in anyway for future searchers on this topic: We have an interesting case study in that the floors in our house and our neighbors' identical house were both redone about five years ago (before we were on the scene, so don't know specific products used). The floors are identical hundred-year-old white oak installed at the same time (same family built both). Both were sanded down, neither was stained, and ours was finished with a water-based finish, theirs with oil-based. Both still look fine five years out (if you ignore the scratches from our dog!) but the looks are different. As someone noted above, the oil finish is a bit warmer and much shinier. I think it's fair to say it looks newer as a result, though how much of that is the wear-and-tear we put on our house (significantly more than our neighbors!) is hard to say. Our water-based finish is more matte-looking and pulls out more browns and beiges than yellows and reds (if that makes sense). There are apparently some differences in how you can clean and touch up the two finishes as well. (We use Bona hardwood cleaner on ours, which seems to work fine.) Anyway, just food for thought on this!

For my adjustable bed, I'm using a flat style box skirt that doesn't have the typical fabric/sheet which is normally sandwiched between the box-springs & mattress. The one I have came from Amazon, and there was a couple dozen fabrics and price ranges to choose from. I attached mine with velcro to the bed base. You can actually use any skirt, just cut away the sheet style fabric from the middle, and use heavy duty velcro, or push pins, to attach it to your base. One tip before you purchase, measure the drop/length from the base to the floor. You'll need to know how long the skirt needs to be. And, Amazon offers many different lengths to fit lots of different heights.

They were super nice and accomodating when I sent in a request through their contact form with my questions. I didn't know they made 96" panels, had a corner seat, or bigger niche with a shelf until I asked. Also providing a "remodelers" trim that allows you to put the panels over existing tile is a huge bonus if you don't want to do a tile tearout. I think they thought of everything so wouldn't be surprised if they do your dual threshold. They sent me the following details on order fulfillment and shipping: "Once an order is placed, it will take 2-3 business days to fabricate and 2-3 business in transit from our Utah factory to get to Denver. The materials are fairly sizable, so they will be strapped to a large pallet and sent on a truck as an LTL shipment. The carrier will call you before making the delivery. They will arrange an appointment with you to make the delivery. You will need to be home to receive the delivery. They will drop the pallet at your front door or in your garage." Made in the USA is a huge plus so there is no delay. Also when I called to place the order we talked to the guy and asked about what aspects people had trouble with on installation and he walked us through his tips and suggestions. We had already watched all their on-line installation videos and read the instructions. Everything seemed doable and was well described.
