A 36 in spring converter with no height range published
FLEXISPOT two-tier spring converter, 36 inch walnut
A 36 in two-tier converter on a steel spring lift with thickened square tubing, rated 33 lb and 4.4 lb — and the only converter here with no height range on its listing.
FLEXISPOT two-tier spring converter, 36 inch walnut
A 36 in surface, which FLEXISPOT sizes for two monitors with room beside them
Mechanical steel-wire spring rather than a gas cylinder, with no pressure to lose
No height range published anywhere on the listing, where every other converter here states both ends of its travel
Best for: A dual-monitor desk where a spring lift is wanted and the height can be checked on delivery.
This is a 36 in two-tier converter on a mechanical lift: a wound steel-wire spring rather than a gas cylinder, which FLEXISPOT presents as immune to the air leakage and gradual loss of force a gas spring can develop. The frame is reinforced steel with thickened square tubes, stated stable at any height, and the two tiers are rated separately — 33 lb on the top surface, 4.4 lb on the keyboard tray. It arrives almost fully assembled; only the tray goes on.
FLEXISPOT sizes the 36 in width for two monitors with room for accessories, and it is finished in walnut. What the listing leaves out is the geometry a converter is bought on: there is no lowest or highest position anywhere on the page, and no depth for either tier. Every other converter on this shelf states its travel — the SANODESK, a different brand on the same spring principle and the same ratings, gives 4.7 to 19.6 in — so here the height is something to confirm with the seller or measure on arrival.
The 4.4 lb tray limit is worth reading too: a keyboard and a mouse fit inside it, a heavy mechanical keyboard with a trackpad may not. It reads about $125 on Amazon.com, against about $110 for the 32 in SANODESK. FLEXISPOT also sells the M57 in 32 in and 42 in widths under the same reference, with the same bullets and the same gap.
What holds up, and what does not
Best for: A dual-monitor desk where a spring lift is wanted and the height can be checked on delivery.
Strengths
A 36 in surface, which FLEXISPOT sizes for two monitors with room beside them
Mechanical steel-wire spring rather than a gas cylinder, with no pressure to lose
Rates the two tiers separately — 33 lb on top, 4.4 lb on the tray
Reinforced steel frame with thickened square tubes, stated stable at any height
Arrives almost assembled — only the keyboard tray is fitted
Compromises
No height range published anywhere on the listing, where every other converter here states both ends of its travel
No depth published for either tier, only the 36 in width
A 4.4 lb keyboard tray rating is low if a mechanical keyboard and a trackpad share it
About $125, against $110 for the 32 in SANODESK spring converter that publishes its full geometry

What buyers ask us first
What height does it reach?
The listing does not say — no lowest or highest position anywhere in the five bullets. The SANODESK in this hub, a different brand with the same spring principle and the same 33 lb and 4.4 lb ratings, publishes 4.7 to 19.6 in, but that is another product, not a figure for this one. Ask the seller or measure on arrival before relying on it for a standing height.
Is a spring lift better than a gas cylinder?
Different rather than better. FLEXISPOT argues that its steel-wire spring avoids the air leakage and loss of force a gas spring can develop over time; a gas cylinder tends to be smoother. Neither claim comes with a cycle figure on this listing.
Does it come in other widths?
Yes. FLEXISPOT lists the M57 in 32 in and 42 in widths as well, under the same reference, with the same bullets and the same 33 lb and 4.4 lb ratings — and none of the three publishes a height range. When we checked, the 36 in sat between the other two in size but was the cheapest of the three; prices on Amazon move, so compare all three before ordering.

A mechanical steel-wire spring rather than a gas cylinder, so there is no pressure to lose over years
Publishes both surfaces — 31.5 by 16.3 in on top, 28.3 by 12.2 in on the tray
The manufacturer reference on the listing is simply "1"
Best for: A standard desk where the lift mechanism should have nothing in it that can leak.
A pneumatic squeeze-handle converter on an aluminum frame, rated to 33 lb — and the only listing on this shelf that names the material of its own work surface.

A pneumatic lift worked by squeezing a handle, rather than by lifting against a spring
Particle board is the cheapest work surface material and the one most easily damaged by moisture
Best for: A converter adjusted several times a day, where a squeeze handle beats a spring you fight.
