FlexiSpot Comhar 48" Electric Standing Desk: problems, parts and running costs
Checked: 2026-10-17
Summary
The Comhar 48 is a single-motor sit-stand desk with an embedded drawer and three USB charging ports, and the owner manual’s own troubleshooting table names its real failure modes: downward sliding, drifting out of position, rising in slow speed, moving in only one direction, and a power-supply module that needs a reset. USB charging pauses whenever the desk moves and laptop charging is explicitly unsupported, and the duty cycle is limited to 2 minutes on and 18 minutes off. Running cost is electricity only — no consumables are sold for it, and FlexiSpot’s US pages showed no live price at research time; the single indicative figure is $429.99 for the glass-top variant from FlexiSpot’s own editorial, undated.
Common problems and fixes
- Downward sliding and drifting out of position — the manual lists “downward sliding” and “frequently reposition” as named faults; the remedy is checking the load against the 110 lb maximum and repositioning. [3]
- Rising in slow speed — a distinct named fault in the manual’s troubleshooting table. [3]
- Only one direction works — the manual lists “only down but not up or only up but not down”, mapped to cable connection, overload and repositioning, and “press the down button and the desk goes down instead of up”, mapped to obstructions underneath or hanging wire harnesses. [3]
- Power supply module not working — the manual’s remedy is to reset first, or wait 1 second after a rise and fall before using it again. [3]
- Electronic functions not responding — the manual points to checking the cable connection; the reset procedure (hold “3” and “4” for three seconds, then hold down until the desk bottoms out and rebounds slightly) re-establishes the low end point, which the manual treats as a normal event rather than an exotic failure. [3]
- Overwork shutdown from the duty cycle — the desk stops if cycled too hard: maximum 2 minutes on and 18 minutes off, then a restart after 18 minutes suspended with power connected. [3]
- USB charging pauses while the desk moves, and laptops are unsupported — FlexiSpot states that USB ports may pause charging while adjusting height and that laptop charging is not supported; output ceases while the desk is in motion and resumes when it stops. [1][3]
- Warranty terms contradict across FlexiSpot’s own pages — the manual and the bamboo page state 5 years for the frame and 2 years for the controller, electronics and other mechanisms, while the wooden Q3 page and the glass page state 15 years for both; assume 5 years plus 2 years until FlexiSpot confirms which applies to a specific order. [3][1][2][5]
Parts and consumables
- Casters — sold separately and not included; moving the desk means buying them. [4]
- Anti-fatigue mat and other Comhar-compatible accessories — sold separately. [4]
- Monitor mounts, cable spine CMP017/tray CMP502, keyboard tray KT2B and foot hammock FH01 — FlexiSpot states these do not fit this desk, so those accessories must come from third parties. [1]
Yearly running cost
Not enough data. The only recurring cost is electricity for lifting and USB charging; the sources publish no wattage, no usage pattern and no consumables for this desk, and casters and mats are one-off purchases, so no yearly total can be computed.
When it is a good buy
- No verified current US price exists: all three FlexiSpot US Comhar 48 pages showed $0 with “SOLD OUT” or “Off Shelf” at research time. [1][2][5]
- The one indicative figure is $429.99 for the glass-top Comhar 48 on FlexiSpot, from the company’s own editorial with no date attached. [4]
- FlexiSpot’s Fall Refresh Sale (2026-10-15) priced the E7 Pro at $369.99, the 4-leg E7 Plus at $499.99 and the E7 at $299.99, with 12% off orders of $200 or more (code FAFSL2). [8]
- Around $300 or below, the Comhar 48 is a reasonable light-duty buy, mainly for the embedded drawer and the USB ports. [8]
- Between $301 and $430 it stays defensible if the drawer and compact footprint are specifically wanted. [8]
- At or above about $430 it is hard to justify: it would cost as much as a nominally premium FlexiSpot desk while carrying a single motor, a 110 lb capacity, a 2 minutes on / 18 minutes off duty cycle and USB charging that FlexiSpot itself says will not run a laptop. [8][1][3]
