As far as folding tray tables go, these are beyond stunning. Most folding tray tables are made out of cheap plastic tops  thin metal tubes for the legs and this set has neither of those materials.

Yes, theyre a but pricey, but the chrome legs and the thick acrylic table top look incredibly luxe. The trays are also quite sturdy and even though we use them on a plush rug, Im never really concerned about tip-over. 

We use these trays when were eating dinner on the couch, since our coffee table is really low. When not in use, they fold easily and go in our pantry for storage (though they are so pretty that we sometimes just leave them out and they build in beautifully with our mid century modern decor).

My only gripe is that these can scratch easily and leave fingerprints too, so we make sure to always use placement when we use these trays. Its a minor inconvenience but expected with anything acrylic if you want to keep it looking pristine.
