If you need a little extra desk space then this is your savior. - It's very easy to install (and presumably remove though I haven't had to yet). Assembly is not tricky at all, even with the folding mechanism. And it seems sturdy enough. I think it's great. If anyone at school makes fun of you for having this instead of simply a larger desk then you go and show them this review. That'll fix `em. Review: Back Pain Gone! Fixed My Posture & Note-Taking Struggles. **Read for tips on installation** - 💡Installation tip: The Anker clamp is adjustable. If it doesn't fit under your desk lip at first, just loosen and reposition the screws to lower the anchor arm (anchor clamp)—I’ve included a photo of the area I mean. Once I did that, it fit perfectly. I truly don’t understand why this has a high return rate—this desk extender is awesome once you know how to install it correctly. I mainly use it as a dedicated spot for my notepad, and it has completely changed my work setup for the better. Before this, I had to move my mouse or awkwardly bend over the far side of my desk just to jot something down. That constant twisting and hunching was wrecking my back. Now, I can take notes comfortably without shifting anything—and my posture has noticeably improved. 🎯 A few more reasons I love it: ✅ The surface is durable and waterproof — no peeling, no bubbling, no chipping ✅ No damage to your desk — attaches with sturdy C-clamps, no drilling ✅ Spacious and strong — easily holds my notepad, mouse, or tablet ✅ Folds away neatly when not in use ✅ Huge ergonomic relief — no more back pain from bad angles I actually bought a small side table before this one, and it bubbled up after a single water spill—so frustrating! This desk tray, on the other hand, wipes clean easily and shows no signs of wear, even after everyday use. Bottom line: This is one of the best ergonomic upgrades I’ve made to my desk. If you’re thinking of returning it because the clamp doesn’t fit—don’t! Adjust the screws and give it a real chance. It's affordable, durable, and way more useful than I expected. ## Features - 𝐔𝐩𝐠𝐫𝐚𝐝𝐞𝐝 𝐒𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞: Our upgraded small desk arm rest is equipped with adjustable double C-clamp, compatible for desks with thickness up to 4.7 inch.

My desk (which is old and I’m looking to replace) is on the smaller side but fits the two monitors just fine. The laptop, however, spends its time on the crafting (un-job-related) bookshelf next to the desk. However, we need to be able to maintain a visual of all 3 screens and the laptop has to be either center or to the right of the other two monitors. Up until now, this has involved me semi-precariously balancing the laptop slightly off the edge of the bookshelf and turned toward me so I can maintain a visual of it. It’s a solid bookshelf and the bulk of the laptop’s weight was supported by the bookshelf, so it wasn’t dangerously placed, but still a hazard. Accidents happen. I have ADHD, and do not sit still, so I shift around A Lot. My dog tends to join me for work and makes himself at home under my desk. Heck, New Jersey (where I live) had a couple earthquakes the other day. All of this lead up to this purchase. All I needed was something to make the top of the bookcase stick out a little longer so the laptop was properly supported. This was it! Exactly what I needed. Easy to assemble. It’s just 4 screws. The shelf is collapsable, in an intentional way—to prevent accidental collapse. It’s sturdy. It’s got some weight to it, but it’s not heavy and won’t topple the bookshelf (plus the bookshelf is also weighted down by the crafting supplies on it). I gave it a good few wiggle tests just to make sure everything was secure and didn’t need tightening. The screws are kind of short and you just screw them through the holes as instructed, so I wasn’t sure how good their hold would be, at first. It’s solid. It does its job and fulfills the exact need I had for it. I’m positively pleased with this purchase and take comfort in knowing my work laptop is secure now. ## Frequently Bought Together - BONTEC Small Desk Extender Tray, 20x9.5 Inch Table Mounted Desk Extender Shelf, 90° Foldable Platform, Clamp on Computer Desk Extender, Suitable for Office Desks, White - BONTEC Ergonomics Desk Extender Tray White, 9.5"x9.1" Table Mount Arm Wrist Rest Shelf, 90° Foldable Elbow Arm Support, Clamp on Computer Arm Rest for Desk, Suitable for Office Home - KDD 4 in 1 Desk Cup Holder - Clamp on Under Desk Headphone Hanger - Rotating Headphone Holder Detachable Pen Cup Holder Desk Storage for Cup, Phone and Pen(White) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/636695397-bontec-small-ergonomics-desk-extender-tray-20x9-5-inch-table](https://www.desertcart.gr/products/636695397-bontec-small-ergonomics-desk-extender-tray-20x9-5-inch-table) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-06-02*
