I was shopping for bed risers, but got confused-- help!
The plastic ones are really cups which you set your bed frame in to. The problem with these is the bed tends to fall over when moved when making the bed. The safety factor here is questionable, especially if you tend to be active in bed.
There are also metal ones that can lift your bed 12" to 15" high, but assembly is cumbersome and the air gets thin sleeping that high. Should you assemble it improperly, safety may be of some concern.
Another type tends to be the easiest and strongest all steel bed riser. Take off your wheel or glide and slide this cylindrical bed riser on. Replace the wheel or glide into the bottom of the riser. Repeat on all of the legs of your bed frame. You must insure that you have the round type leg that will fit into this bed riser; the flared end of the riser accepts bed frame legs that are round and about 1/2" to 3/4" in diameter. Check the specifications; some come for glides, some for use with wheels or casters.
The last type is made by Leggett & Platt for use with their bed frames, it has the durable polypropylene riser along with a steel shank and adapter that fits into the bed frame leg itself. This insures accurate and safe fitting each time; these Pro Glides are made for some of their better bed frames and can be purchased together.
