What a letter tray is actually for
A letter tray solves one problem: paper that needs to sit somewhere between ‘just arrived’ and ‘dealt with’ without turning into a pile on your keyboard. That’s it. It’s not a filing system — if you’re storing things long-term, you want a real cabinet, and I’ve written up what’s worth buying on Amazon over on the file cabinet guide. A letter tray is for the in-between: mail you haven’t opened, invoices you haven’t paid, forms someone needs to sign today.
Stacking trays vs sliding trays
You'll find most letter trays sold online fall into one of two basic styles. Stacking trays rest flat on top of each other — they're inexpensive, straightforward to use, and work fine if you seldom need to grab something from a lower tier without moving everything else. Sliding trays have interlocking edges so you can pull any single tray out without disturbing the ones stacked above, which turns out to be way more useful than you'd think when you're juggling multiple levels and hunting for something buried underneath. For a single tray going on your own desk, I'd go with the sliding design. For a bulk order you're distributing across a few people, plain stacking saves money and makes sense — nobody's usually hunting through multiple levels on someone else's workstation anyway.
Plastic mesh vs acrylic
The other real decision is material. Mesh and molded plastic trays are the cheapest and do the job invisibly — nobody’s judging your inbox tray. Acrylic costs a few dollars more but looks noticeably tidier, which matters if the tray sits somewhere clients see it, near a shared breakroom counter, or on a reception desk. Acrylic brochure holders sized for standard letter paper work just as well as trays marketed specifically as ‘letter trays’ — the physical shape is nearly identical, they’re just sold to a different audience. Don’t pay a premium for the word ‘letter tray’ in the title if a brochure holder does the same job for less.
Capacity and what happens when you outgrow it
Three tiers is enough for most single desks. If you’re the person who ends up sorting incoming mail, signed contracts, and outgoing invoices for a whole small office, go to four or five tiers rather than buying a second three-tier tray later — it’s cheaper and it keeps everything in one stack instead of two. If you’re regularly generating more paper than a five-tier tray can hold, that’s less a letter-tray problem and more a sign you need an actual desk organizer setup or a proper filing cabinet, and possibly a look at your printer and scanning workflow so less of it needs to exist on paper at all.
What to skip
Don’t buy a letter tray expecting it to lock or protect anything — if you’re storing something sensitive, that’s a job for a safe or a locking cabinet, not an open plastic tier. And don’t buy five-tier towers for a desk that gets three pieces of paper a week; a taller tray you don’t fill just becomes a place things pile up sideways instead of stacking properly. Match the tier count to your actual mail volume, not your ambitions for it.
How I picked these
I dug through the product pages and studied the review feedback for everything here, zeroing in on the patterns — whether people consistently mention things like trays not staying locked together or confusing assembly steps — rather than just looking at star ratings, since a 4.6 with a specific recurring complaint actually tells you more than a 4.7 where nothing gets mentioned twice. I haven't personally stacked and tested these myself or measured them under weight; I'm working from what the product information and customer reviews actually report, not from hands-on testing. Any listing that didn't have substantial reviews behind it got skipped rather than included based on assumptions.
For the rest of your desk setup, the desks hub and desk comfort guides cover what sits around the tray, and office utilities is worth a look once you’re generating enough paper to need a shredder alongside it.
