Update 11/6: Price dropped to $340 from $350.
We bought our first one of these mattresses back in 2016. Prices back then were even lower (I think we paid $280 back then?). The foam had started to get softer over the years, and a couple of months ago we bought a second one to replace it. The price we paid on September 15 was something like $450.
Today I got notice that the price dropped down to $349.99 -- maybe this is the new low in recent times. I doubt this mattress price will go back to 2016 prices.
Love this mattress. It's firm enough, and the last one we had lasted over 5 years, and we probably could have made it another couple years but we had the extra budget. No regrets getting it at $450, so $350 would have been zero hesitation.
One thing about nearly all of these bed-in-a-box mattresses is that you should NEVER remove the outer cover (even though it has a zipper). To make these mattresses fireproof, they line the inside of that outer cover with a fiberglass like material (all mattresses at this price point do it). If you remove the outer cover, you'll get fiberglass shards all over and it will be a nightmare to clean up. Our mattress that was in service for over 5 years, the bottom side of it seemed to have some fiberglass-looking shiny fibers when shined with a flashlight. I looked when we hauled it to the curb for trash pickup. I didn't get any irritation, so I have no bad story to report. But if you do some research, you'll find lots of horror stories about fiberglass woes. Just wanted to make sure everyone knows about this. We're fine; we put a standard water proof mattress protector on top of the mattress and then put our regular sheet on top of that so we never had a reason to have to take their cover off to wash.

Queen version is same price as this Zinus. It's Costco, so easy returns. There's no fiberglass per the Manufacturer here:

I didn't know there was a lawsuit. Will join it even if I get nothing out of it.

Got a notification about the class-action lawsuit for people who opened the cover. Not going to join the lawsuit as I wasn't that dumb and don't want to punish a company I had a good experience with.
