Smart Companies Cater to Your Needs
You are right to ask this question. Key to getting what you want is to look. Good companies ask the related question - "What makes our workers productive and comfortable?"
Smart companies cater to not just the needs you mentioned, but perhaps also after hours and weekend meals. Some like Google, all day every day.
In his book "Smart and Gets Things Done", Joel Spolsky recommends companies get developers a top of the line chair (like the $800 Aeron chair). Benefits like durability, comfort, making top talent feel welcome, could result in your sitting in that chair a few more hours a month (which quickly pays for the cost of the chair, monitor, etc.).

Companies should resource to win, and good tools are important and cost effective.
Caution - Don't Ask too Early, Don't Get Carried Away
Let's talk about your first date (interview) with your prospective company.
Don't initiate a discussion of what you want before they have offered you a job. Get in their head and see yourself through their eyes. Many companies are having a rough time, but they may have a best fit job for you (except for the seat, monitor, mouse). Until you have some offers, take a wait and see attitude about whether you are hot or not (at least in the eyes of hiring managers). Take away every perk at Google and it might still be a top place to start and grow your career.
I was involved with an interview where the candidate's first question was a suggestion that he should get his own office. We had no cubicles, but most people shared an office with one other person. If you were CTO, CEO, chief software engineer, or needed to quiet to call on customers all day, you had your own office. The owner/CEO showed a lot of grace about this guy's lack of awareness. But the candidate did not get an offer.
