Midmark · Dental Equipment · $7,000 – $15,000
You'll see $7K–$9K for chairs with 12,000–15,000 patient hours logged and full service history; $11K–$15K for sub-8,000 hours with recent Midmark factory service. A 3-year gap in maintenance records drops value $2,000–$3,000 because you're buying unknown wear on the valve assembly.
Sit in it for 2 minutes - if the back doesn't lock firm at full recline, the tilt cylinder is leaking and that's a $1,200 swap. Listen for grinding sounds when cycling the chair up/down; that means the lead screw needs lubrication or replacement ($600–$900). Check the foot control for dead spots; if it sticks midway, the pneumatic line is collapsing.
California and Texas have constant demand because DSO expansion (Sage Dental added 85 locations in 2022) creates trade-in volume and drives used prices up 8–12% annually. Nevada is softening because too many chairs flooding the secondary market from Pacific Dental consolidation.

If it's got clean service records, you get 4–6 more years easy. But the real question is the control box; if that's original and cracking solder joints, you're looking at random failures. I'd do the hydraulic rebuild ($1,400 parts + labor) only if the electronics have been serviced in the last 24 months.
Because it doesn't break as often. Belmont seats are 18–24 months between major repairs; Midmark UltraComfort runs 36+ months. Your service guy knows Midmark. You don't need to call an emergency tech on Tuesday night, which happens with Belmont at least twice a year per chair.
The XR has memory presets (saves position) and a larger 350 lb capacity, but it's $24K–$28K new. If your hygienists don't care about memory and you don't have patients over 300 lb consistently, you're paying $8K–$10K for a feature you won't use. Stick with the standard UltraComfort.

I can move a Midmark UltraComfort in 6–8 weeks versus 18 weeks for a Belmont or A-dec chair because the brand recognition is there and financing approval rates run 92% versus 78% on other brands. That's the difference between cash flow now and cash flow next quarter for a broker.
