We were like this too. Software company selling to banks. Office in the financial district, most people WFH 2-3 days a week.

During COVID my employer cancelled our lease and closed the office (about 50 people there), everybody permanent WFH. Most of the people I talk to were disappointed, the office was awesome and it was nice to have lunch together. I ended up moving out of the city and live out in the suburbs now. Since we no longer have an office I rarely speak to some of the folks I used to have lunch with. We work in different departments. Sad.

Google “mattress disposal near me” and you will probably find a few options. You may have to pay if you aren’t able to transport the old mattress somewhere yourself.

Also, if you are buying a new mattress, I suggest asking the seller if they can take the old one. Some will. I’m surprised this new regulation doesn’t also require them to begin doing that too. Some states already have that.

Edit to add that the local dump near me recycles them for free if you have a sticker.
