Not any experience with it, but I wouldn't trust any Amazon mattress brand. They are all dropshipping companies that use the same low-quality supplier.

If you are looking for something high-quality and budget-friendly you may check out GhostBed. They have a special discount right now where you can get a full-size latex & gel memory foam + 2 free pillows for $907. They have 101-day sleep trial and free returns if things don't work out. I sleep on the Classic for the last 6 months and am really satisfied, it easily antagonizes the more expensive premium brands. Very good motion isolation, edge support and durability. Also very breathable and doesn't overheat at night.

The Puffy is another good alternative (more plush) for someone with musculoskeletal issues and designed for all sleeping positions.

All above options are hypoallergenic, fiberglass-free, don't smell, sleep cool, etc.
