The ergonomic target is for the top third of your screen to be at or just below eye level when you're sitting in your normal working posture. The exact height depends on three variables: your chair height, your desk height, and your monitor size. Most standard desk setups (desk at 29–30 inches, chair adjusted for the person) benefit from 4–6 inches of lift.

Quick self-test: sit at your desk with your back straight, look straight ahead — where does your gaze land on your monitor? If it lands below the center of the screen, your monitor is too low and you need more lift. If it lands above center, your monitor is already high enough or too high. Most monitors sit too low by default, especially on IKEA-style desks where the monitor base barely elevates the screen. A 4-inch riser (the most common) fixes this for most people between 5'4" and 6'0". If you're taller than 6'0" or use a particularly low chair, look for a 5–6 inch riser.

Side-pressed bamboo laminate — the type used in quality risers like ROCDEER and SONGMICS — handles 30–50 lbs without sagging or warping. The side-pressing process binds the bamboo fibres horizontally under high pressure, producing a board that's significantly denser and stiffer than vertical-pressed bamboo or MDF. Real-world reports from users with heavy 32-inch monitors (which weigh 12–18 lbs) and ultrawide monitors (up to 22 lbs) consistently show no deformation after 2+ years of use with reputable brands.

Where bamboo fails is with cheap bamboo veneer over MDF core — these look identical to solid bamboo in product photos but the MDF core absorbs moisture and sags under sustained weight. The tell: check whether the product listing says "bamboo" or "bamboo veneer" — real bamboo risers list their weight capacity (30 lbs+). Metal risers are the safe choice if your monitor exceeds 22 lbs or you want zero long-term concern about material fatigue.

The drawer on a standard monitor riser is typically 1–2 inches deep and 12–16 inches wide. That rules out bulky items. The most useful things to keep there: USB sticks and SD cards (impossible to find in a bag, easy to lose on a desk), charging cables for items you use at the desk but don't leave plugged in (headphone cable, portable battery cable), sticky notes and a few pens, earbuds or earphones, a small notebook, and business cards. The drawer is also the ideal home for desk essentials you want within arm's reach but not visible — a small multi-tool, cable ties, spare batteries. The rule: if it's something you reach for 2–4 times a week at the desk and it's small enough to fit, put it in the drawer.

A dedicated dual monitor riser is better in almost every case. A proper dual riser (35–42 inches wide) provides a continuous, level surface across both monitors, keeping them at identical heights with no gap or step between them. Two separate single risers placed side by side introduce alignment problems — even 2–3mm of height difference between the two risers is noticeable and causes subtle eye strain as you track between screens. They can also shift independently over time.

The only case for two separate risers: if your monitors are significantly different sizes (say a 27" main and a 24" secondary used in portrait mode) and you want them at different heights intentionally. In that case, two independently positioned risers give you flexibility that a fixed dual riser can't.

Two things to check: the feet and the weight. Quality bamboo and wood risers use rubber or silicone non-slip feet that grip glass cleanly without scratching. Metal risers sometimes have plastic feet — check the listing for "rubber feet" or "non-slip pads" before buying. If your riser only has bare plastic or metal contact points, add self-adhesive felt or rubber pads underneath (a pack costs $3–$5 and is available on Amazon).

Sliding is less of an issue than scratching — a 30 lb monitor sitting on a riser generates enough downward force to keep most risers in place even on glass. The main risk is placing or removing the riser from a glass desk carelessly. Always lift, never drag. For maximum safety on a glass desk, a metal riser with confirmed rubber feet is the cleanest choice.

A monitor riser is right if: you're happy with your current monitor position and just need it higher, you want under-desk keyboard storage, you want a drawer, and you want to spend $25–$55. It's fixed-height, stable, requires no installation, and works on any desk.

A monitor arm makes sense if: you regularly adjust your monitor height throughout the day (sitting to standing desk transitions), you want to pull the monitor close or push it far back, your desk is very small and you need to reclaim the monitor base footprint entirely, or you have multiple monitors you want to position precisely. Monitor arms cost $35–$150+, require drilling or a desk clamp, and take 20–30 minutes to install. The ergonomic advantage is real but only if you actually use the adjustability. Most people don't — they set the arm once and never adjust it, making a riser the more practical choice.

It depends on the material and brand. Metal risers (like the gianotter) typically arrive fully assembled — open the box, place on desk, done. Bamboo and wood risers vary: some arrive assembled, some require attaching legs to the platform (usually 4–8 screws, takes 5–10 minutes). The product listing will say "no assembly required" if it's true. If it doesn't say that, assume some assembly. The gianotter metal riser and ROCDEER bamboo line are both specifically noted for arriving ready to use. SONGMICS and TINAMO risers typically require brief leg assembly but include all tools.
