I helped some friends move once and they had a set of these. Made moving mattresses and furniture too awkward/fragile for the hand truck much simpler. I’ve seen the same basic idea used by appliance delivery men (one or two long, wide webbing strap looped under something and lifted by someone on each side) but this is nicely finished and padded, for a lot less than I suspect it would cost to obtain similar materials.
