Question: What is the height?
Document: I really like these tables ..They are cheap but I like the size and the height is wonderful...They will serve my purpose for just eating in front of the TV.
I've been looking for this type of TV tray for a while, but so many styles are heavy, or have a cross piece between the legs that restrict leg movement. As a senior citizen with back and knee problems, I find these trays to be very light and easy to move around. The top is very roomy and a good height for eating and working at my laptop, which are the main things I use them for.
My husband and I are very satisfied with the set of two, honey-colored TV trays that I ordered recently. They both sit level, are a comfortable height, and the tray top has a nice finish and is ample in size; plus it has a slight lip around the edge that keeps things from rolling off. It is lightweight, so easy to move about; but we haven't had a problem with tipping. Perfect for anyone looking for a simple, economical TV tray.
I want to be able to stretch my legs underneath the table so these tables allow you to stretch your legs. Its almost impossible to find these tables with out that cross piece at the bottom of the leg. I'm glad I found these. The table is nice in sturdy .They don't tell you the height of the table . The table is 24 inches from the floor to the top of the table. The table top is 21 inches wide by 15 inches depth.I would buy more of these tables.
was very disappointed in the quality of this table. It is very cheaply made with low quality materials. The "laminated" top consists of extremely thin Masonite with wood grain printed on the top.
tv trays were what we have looked for several years were a good  price and  received at our front door sooner than expected
they work just as you would imagine- light weight, easy to fold and lift and set up. because they are light and top heavy, they could be easily knocked over (by one's dogs, for instance). I don't put a wine glass on them. but the easy lightness was their main appeal.
there is not much you can say about a tv tray. These are just fine for our nightly tv watching. Shipment was quite fast, and I ordered more than I needed, but will put the extras away for later.
tables are very flimsy, therefore you don't want to trust it to let the kids eat off of them. feels like any little thing could knock it over.
loved this  .may me think of the old dayseating  meals  in front of the TV watching a big game
Answer: 23 1/2 inches
