Earth to Manufacturer: a person confined to bed does not need locking casters on a rolling table. Because they will not stay unlocked, I will be replacing them with non-locking casters. Casters that lock themselves make the table very difficult to move. The casters do not maneuver easily over carpet, anyway; I bought one of those heavy plastic office chair mats to cover the carpet. Assemble with EXTREME CAUTION. ALWAYS HOLD THE ENDS OF THE SPRING-LOADED COLUMN POINTED AWAY FROM YOUR FACE. The assembly instructions contain a brief warning about this hazard, but it should be printed on the front page, in 36-point Helvetica Bold. The spring-loaded column could release tension and knock out teeth or break bones. My son was not holding the piece when it released, but the violence of the release was still a rude shock. The part needs to have a long screw all the way through the column to keep it secure until assembly is complete. (If the little screw on one side of the column was supposed to perform that function, it completely failed: it was too short, it was loose in the hole, and the threads were full of plastic, presumably from the plastic liner of the column.) When first assembled, it does not seem that the height adjustment latch will function to keep the table top at the desired position, but when in use with a small amount of weight atop the table it works adequately. Perhaps weights could be added to the underside of the table top (in a couple of the many rectangular spaces there) to keep the height in a desired position when there is no load. The table rises high enough to be clear of the foot of a hospital bed that's been raised to its highest position. Otherwise, the table appears well made. The welds look good on the H-shaped platform, and the casters screw securely into their holes. The top is made of thick gray plastic with a slight countertop rim to it, and it should hold up better than a laminated, edge-banded particleboard top would. I'm not sure how beneficial the textured surface will be, but it's because of the texture that the surface is easily scratched, and the scratches are readily apparent. The assembly instructions also could stand some updating and revision for clarity, because they're used to describe more than one model of table. For best in-bed-use results, position the table on the side of the bed that corresponds to the dominant hand of the bed's occupant. Otherwise, position the table on the side of the bed opposite to the side from which the occupant will exit the bed: this is why the table does not extend all the way across a twin or hospital bed (if it did, it would obstruct the way to get out of the bed). This product is a decent value for the price, and it's not difficult to assemble, but it lost points for the injury risk, the need for a little extra weight to the table top, poor maneuverability due to casters that won't stay unlocked, and the ease with which the table top surface can be marred with scratches (if possible, I'd give it a 2 1/2 instead of a 3-star rating).
