FlexiSpot M7 vs Branch Desk Riser: Which Converter Should You Buy?

$99.99 against $249. That gap looks like the whole story, and it isn’t. These two converters are built to different architectures — the M7 stacks a monitor deck above a keyboard tray, the Branch raises one flat platform — and almost every spec that separates them, including the one that should decide your purchase, follows from that single design choice.

The Short Answer

For most people, the FlexiSpot M7 is the one to buy. It’s our best overall converter: $99.99 for the 28″ model, a one-handed gas-spring lift, 33 lbs of desktop capacity with a separate 4.4 lb keyboard tray, and 20.1″ of travel — the more generous standing range of the two by a clear margin.

The Branch Desk Riser wins in one specific case, and it’s an important one: you sit for most of your workday. Its single-platform design collapses to 2.5″ against the M7’s 4.7″, which keeps your seated typing height close to your desk’s own. Over six or seven seated hours, those 2.2 inches are the difference between a mild ergonomic compromise and a real one.

What you give up for it is more than the $150: no separate keyboard tray, 7 lbs less on the working surface, and a ceiling 4.3″ lower. So the deciding question isn’t budget. It’s two questions — how much of your day are you actually seated, and how tall are you when you stand?

The Full Spec Comparison

Both are manual converters that sit on the desk you already own, and neither has a motor or memory presets. Everything below flows from one difference: two tiers versus one.

What’s Actually Different — and What Isn’t

Two tiers versus one platform

The M7 is a conventional two-tier converter: a monitor deck on top, a keyboard tray hanging below it. Your screen and your hands sit at properly different heights, and neither has to move when you raise or lower the unit.

The Branch is a single flat platform. Monitor and keyboard share one surface unless you buy the $99 Desk Shelf, which lifts the monitor above the platform. That’s the trade: the Branch gets its slim collapsed profile precisely because it doesn’t carry a second tier, and it loses the keyboard tray for exactly the same reason. Neither architecture is better in the abstract. One suits a sitter, one suits a stander.

The 2.2 inches that decide it

At its lowest setting the M7 still adds 4.7″ to your desk. The Branch adds 2.5″. On a standard 29″ desk, that’s a seated typing surface at 33.7″ versus 31.5″.

Whether that matters depends entirely on your split. If you’re seated for six or seven hours a day, the M7’s extra height raises your keyboard above a neutral typing position for most of those hours — shoulders creep up, wrists bend back. That’s the case for the Branch, and it’s a real one. If you stand frequently, or you bought a converter specifically to break up long sitting stretches, you’re not parked at the lowered position long enough for 4.7″ to cause trouble, and you’ve saved $150.

The ceiling nobody mentions

Here’s the spec that runs the other way, and almost no comparison covers it. The M7 reaches 20.1″ above your desk. The Branch platform reaches 15.8″.

On that same 29″ desk: the M7 puts your keyboard at 49.1″ standing, the Branch at 44.8″. If your standing elbow height is above roughly 45″, the Branch alone won’t get you to a neutral standing posture — you’d be reaching down all day, which defeats the point. The Desk Shelf raises the monitor to 20.8″, which fixes your screen height but not your hands.

Measure your own standing elbow height before you choose. It’s the single check that rules one of these two out for some readers, and it takes thirty seconds.

Capacity: 33 lbs versus 26 lbs — and why the tray is a separate number

FlexiSpot rates the M7’s desktop at 33 lbs and its keyboard tray at 4.4 lbs. Those are two limits, not one pool — you can’t put 37 lbs on the deck because the tray is rated for the balance. The Branch has a single surface rated at 26 lbs, the lowest of any converter we recommend.

So the M7’s real advantage on the working surface is 7 lbs, not the double-digit gap a summed figure would suggest. A 27″ monitor typically runs 10–15 lbs; add a laptop and you’re past 20 lbs before a second screen enters the picture. That puts the Branch out for dual monitors and makes the M7 tight rather than comfortable. Weigh your gear on a bathroom scale if you’re anywhere near either line.

Where the Branch earns its $150

Materials, mostly, and they’re not cosmetic. The Branch is 9-ply laminated plywood with an HPL top and bottom, rounded corners, a curved comfort edge, and an aluminium base in four finishes. It meets BIFMA’s commercial-grade durability standard. Its footprint is 31″ × 24″ at every height — collapsed, extended, or with the shelf — so it never creeps forward as it rises. At 22.5 lbs it locks flat and lifts off the desk entirely, genuinely useful on a shared desk, in a small apartment, or anywhere the riser shouldn’t be a permanent fixture. The M7 is black, stays put, and looks like office equipment. If your converter lives in a room where looks count, that’s a real difference.

What’s effectively the same

Both are manual, so you lift your own gear at every switch. Neither has memory presets or a motor. Both need a desk deep enough to take them — measure front to back, not just width. Both are one-person setups. And both add height when lowered; the question is only how much.
