📦 Estimated Delivery Time
Orders typically ship within 3–4 business days once processed. You'll receive tracking details as soon as your order leaves the warehouse.

⏱ Order Processing
In-stock items are processed and dispatched within 1–2 business days. You'll receive two emails: one confirming your order, and one with your tracking number once it ships.

📸 Photo Proof of Delivery
Every shipment includes Photo Proof of Delivery as standard, giving you an added layer of confidence that your order has arrived safely. If you'd prefer this removed from your order, reach out to us before your shipment goes out and we'll review your options. Please note that removing this protection means we're unable to file a claim with the carrier on your behalf, so we recommend keeping it in place.

Note: Some orders may ship in multiple packages. If your order has more than one item, don't be surprised if they arrive separately — a second tracking number usually follows within 1–2 business days.

M/Flex · M2 Pro

Two screens, aligned around your work.

Bring two displays together without filling your desk with monitor stands. This M/Flex configuration combines M2 Pro arms with sliding screen adjustment, so you can refine the space between your monitors and position each display independently.

M/Flex M2 Pro — dual monitor arms with sliders

“Best monitor arm w/ built-in dock.” — PCWorld

Press comments refer to monitor-arm and docking configurations. Charging, USB data and docking functions depend on the technology package selected.

Screen spacing, made easier.

Screen spacing, made easier.

Slide the monitors side to side to bring their edges into alignment or make room for a different task. The sliders provide another way to fine-tune the layout without repeatedly moving the entire arm. This is a side-by-side, two-monitor configuration; it is not the stacked or triple-screen version.

A separate position for each screen.

A separate position for each screen.

Set the height and distance of each display to suit the work in front of you, whether you are comparing documents, keeping reference material nearby or sharing a screen with a colleague. This slider configuration supports monitors weighing 3–12.5 lb (1.4–5.7 kg) each. Check the weight of each screen without its original stand, its VESA mounting pattern and the available clearance before ordering.

A modular base for a changing workspace.

A modular base for a changing workspace.

M/Flex is built around interchangeable components that can support later changes to a workstation. The configuration sold here holds two screens on M2 Pro arms with sliders and a desk clamp. Future additions require the appropriate compatible parts; extra screens, extension posts and conversion components are not included.

Assembly with connections that click into place.

Assembly with connections that click into place.

Quick Release joints help simplify installation and later adjustments to the setup. Secure the mount to a suitable desktop, assemble the links and attach the screens according to the installation instructions. Balance each arm for its own monitor load before using the full range of movement.

Movement with the right limits.

Movement with the right limits.

The supplier lists 360° arm rotation with optional 90° or 180° stops, 32° left/right monitor pan, 30° upward tilt and 15° downward tilt for this slider model. These values differ from the standard single-monitor M2 Pro. Maximum listed monitor width is 36 in (914 mm); screen shape and desk clearance also affect whether a setup will fit.

A clearer route for your cables.

A clearer route for your cables.

Integrated cable management keeps cords close to the system as the displays move. Allow enough slack at the joints, then check every cable across the intended working range. Keeping the surface below the monitors open leaves useful space for a keyboard, notebook or the tools you use throughout the day.

Finish, VESA colour and connections—chosen separately.

Choose Black, Silver or Polished Aluminum for the arms, then choose a Black, Gray or White 100 × 100 mm VESA plate. No M/Connect supplies the monitor-arm configuration on its own. The M/Connect 3 Charging Hub, USB Data Hub and Pro Dock are separate technology choices with different functions. Check the selected package and your laptop’s requirements before ordering; the SKU, images and price follow your choice.

Materials and a longer useful life.

Materials and a longer useful life.

Die-cast aluminium forms the structural components, with powder-coated surfaces on applicable finishes. The modular design supports maintenance and compatible changes over time. The supplier lists product declarations, indoor air quality testing and sustainability certifications for M/Flex; find the details in Trust & Care. The arm has a listed 15-year warranty, while optional M/Connect 3 electronics have a 3-year limited warranty, subject to the manufacturer’s terms.

Who it’s for.

Customer Reviews

Have a question?

We're Here to Help!

What warranty comes with standing desks?

Warranty coverage varies by product category. Many of our seating and desk-base products carry warranties of up to 15 years, with shorter coverage on select components such as fabric, cushions, and arm pads. All warranties apply to the original purchaser only and are non-transferable. Full warranty terms for a specific item are listed on that product's page.

What does the warranty cover?

Our warranty covers defects in materials and workmanship. At the time you receive your product, it will be in good working order and free from such defects for the duration of the warranty term listed on that product's page. If a covered defect is confirmed, we will repair or replace the product or part with the same or a comparable item — repair or replacement does not restart or extend the original warranty period.

What is NOT covered by the warranty?

What the warranty does not cover:

  • Normal wear and tear
  • Damage from accidents, neglect, misuse, or failure to follow the included installation or usage instructions
  • Damage from service, maintenance, modifications, or tampering performed by anyone other than an authorized representative
  • Damage occurring during carrier transportation, or alterations made by the owner
  • Acts of God, electrical power issues, or failure to perform routine preventative maintenance
  • Parts, components, or peripherals not supplied by us
  • On leather-upholstered items: natural characteristics such as growth marks, scars, veins, or grain variation, which are typical of genuine leather and not considered defects
  • On electric height-adjustable table bases: modifying or tampering with any part of the base voids the warranty

Warranties apply only to the original end-user purchaser, are non-transferable, and require proof of purchase through us. Full terms specific to each product are listed on that product's page.

Do I pay shipping for a warranty replacement?

If your item arrives damaged, shows shortages, or has a delivery issue, note it on the delivery receipt at the time of delivery if possible, then contact us within 24 hours with your order number and photos. We handle the freight claim directly and will review it to determine next steps, including replacement or credit where appropriate.

How do I file a warranty claim?

Contact us at support@apexstand.ca with your order number and photos or a short video showing the issue. We'll open the case and manage the entire process for you.

What height range and weight capacity do your desks and chairs support?

Height range and weight capacity vary by model and configuration. Exact figures — including specific load and surface requirements for electric desk bases — are listed in the specifications section of each product page.

What desktop materials are available?

Depending on the model, worksurfaces are available in the following materials:

  • Powder-Coated MDF — a durable, formaldehyde-free core with a smooth, wear-resistant finish
  • Laminate — a scratch-resistant, high-pressure surface bonded to a formaldehyde-free MDF core
  • Solid Wood — natural grain construction that can be refinished over time

Available materials vary by product and are shown on each product page.

Do I need to assemble my furniture?

Some products require light assembly, while others arrive ready to use. Assembly instructions are included where applicable. Professional installation isn't included with online orders but may be requested for an additional fee (minimum 315 CAD, subject to availability and region).

How do I place, track, or change my order?

  • Place an order: Add to cart and check out at apexstand.ca. Need help choosing? Call (514) 447-7026 or email support@apexstand.ca.
  • Track your order: Once your order ships, you'll receive tracking information. All parcel shipments include photo proof of delivery and require a signature upon receipt.
  • Change or cancel your order: Orders may be modified or cancelled within 24 hours of placement — contact us as soon as possible, since we begin processing orders quickly. Changes requested after 24 hours may not be possible once the order has entered fulfillment.

What is the return policy?

We offer a 30-day satisfaction guarantee. If a return is requested within 30 days of receiving your product, we provide a prepaid return label, provided the item is in resaleable condition and proof of purchase is included. Returns requested between 30 and 90 days may be considered at our discretion and are subject to a 15% restocking fee. All returns require prior authorization — email returns@apexstand.ca to begin the process.

How long do refunds take to process?
