Four Leg Standing Desk

The Four Leg Standing Desk is an adjustable sit-stand desk designed for home offices, workspaces, and commercial-grade use. Four hidden motors raise the desk in unison for seamless transitions between sitting and standing. Its familiar four-leg silhouette has rounded corners, a minimal steel frame, built-in cord management, and elegant edge detail. An intuitive LED control paddle offers three memory presets, while collision detection supports the 17-inch adjustment range from 27.3 to 44.6 inches. The desktop is made from plywood or melamine and MDF, with a powder-coated steel and cast aluminum base. It supports up to 225 pounds when lifting and 450 pounds statically. Available in 48 x 27-inch and 59 x 27-inch sizes, it requires assembly and is compatible with the optional Cable Organizer, with or without a power strip. Meets BIFMA standard and is backed by a 10-year warranty.

Frequently Asked Questions
If you can’t find what you’re looking for, please reach out to support@withflex.com.
1. At checkout, select "Flex | Pay with HSA/FSA." 2. Enter your HSA/FSA card details and complete your purchase. 3. If you don’t have your HSA/FSA card available, use a regular credit or debit card. Submit your purchase to your HSA/FSA administrator for reimbursement.
Health Savings Accounts (HSAs) let you set aside pre-tax dollars to pay for qualified health expenses. HSAs are linked to high-deductible health plans, and funds in these accounts roll over year after year. Flexible Spending Accounts (FSAs) allow you to use pre-tax dollars for eligible health expenses. Unlike HSAs, FSAs are not tied to a specific health plan and often require you to use the funds within the calendar year. FSAs are typically provided by employers.
At checkout, select "Flex | Pay with HSA/FSA." Some products require a Letter of Medical Necessity. Complete a brief chat-based telehealth consultation to confirm eligibility if required. Enter your HSA/FSA card details and complete your purchase. If you don’t have your HSA/FSA card available, use a regular credit or debit card. Submit your Letter of Medical Necessity and itemized receipt (provided by Flex) to your HSA/FSA administrator for reimbursement.
HSA and FSA cards are debit cards, and the most common reason for declines is insufficient funds. Reach out to your HSA/FSA administrator to confirm your balance.
If you don’t have your HSA or FSA card handy, still select “Flex - Pay with HSA/FSA” as your payment method. Enter your credit card information and Flex will email you an itemized receipt to submit for reimbursement.
A Letter of Medical Necessity is a document from a licensed healthcare provider that verifies the medical necessity of a product or service, making it eligible to purchase using your HSA or FSA. This might include items or treatments like supplements or physical therapy that aren’t automatically recognized as eligible expenses.
A licensed clinician will determine your eligibility during a chat-based telehealth consultation. According to IRS guidelines, you must have a medical condition that warrants the product or service you intend to purchase using your HSA/FSA. A range of conditions, such as cardiovascular, metabolic, musculoskeletal, autoimmune, neurological, or mental health conditions, could qualify.
Your Letter of Medical Necessity is valid for 12 months from the date of issue. It can be used for any eligible purchases made during this time. Be sure to keep and submit all related receipts when filing with your HSA/FSA administrator.
You should keep it on file for at least three years in the event of an IRS audit of your HSA or FSA account. Occasionally, FSAs may ask for the Letter to confirm the eligibility of your purchase.
All products shown in the Flex Marketplace are HSA/FSA eligible, some may require a Letter of Medical Necessity (LMN). Branch may also offer additional eligible items on their website. When shopping directly on Branch's site, look for HSA/FSA messaging on individual product pages. Flex accepts HSA/FSA cards, credit/debit cards, and split payments. Select Flex at checkout to pay for your purchase.
