Midmark · Dental Equipment · $7,000 – $15,000
A chair with under 12,000 cumulative recline cycles and full service records from the past 18 months hits $12,500–$15,000; gaps in maintenance history or visible hydraulic fluid seepage drop you to $8,000–$10,000 fast.
Check the foot control pump for hissing or lag - replacement runs $1,200–$1,600 and buyers will dock you for it upfront. Look under the seat base for hydraulic drips or staining; even small weeps signal a $800 rebuild. Run 10 full recline cycles and listen for grinding - smooth is $14k territory, rough is $9k.
California and Texas markets favor UltraComfort because large DSO chains (Heartland Dental, Sage Dental) standardize on Midmark in those regions and need inventory rotation. A chair in working condition moves in San Diego or Dallas inside 10 days; rural markets add 3–4 weeks.

Yes. Standard 4-hole ASME mount pattern on the backrest. Most arms bolt straight on. Some older arm models need a $150 adapter bracket - call it out in your listing if you know the history.
12,000–18,000 recline cycles before hydraulics need attention. If your chair was used 8 hours a day for 5 years, that's roughly 10,000 cycles - you're in the solid middle of the range. Clinics typically replace chairs at 20,000 cycles or when repair costs exceed $2,000 in a year.
Buyers find out the foot control doesn't hold pressure or the backrest sticks at 45 degrees. Both are fixable but cost $1,500–$2,000 combined, and most walk instead of negotiating. Get it tested before you list.

I place UltraComfort units for clinics doing equipment refresh - I handle transport ($800–$1,200 depending on distance), document condition, and match you with a buyer in 2–3 weeks instead of you listing it yourself for 8 weeks. Saves you time and uncertainty.
