What weight is this VEVOR king blanket?

The listing does not state a fill weight. Weighted blankets are usually chosen at about 10 percent of body weight, so confirm the weight with the seller before buying.

Does 80 by 87 inches fit a king bed?

Yes. A standard king mattress is 76 by 80 inches, so 80 by 87 inches drapes over the sides and foot with a little overhang.

Yes, the material is listed as cotton in gray. Cotton breathes better than polyester but stains more easily, so a duvet cover helps.

Can it be machine washed?

Cotton weighted blankets with glass or plastic fill are usually spot cleaned or washed cold on a gentle cycle and air dried. Check the care label, since heavy wet fill can damage the shell.

Is $59.90 a good price?

It is the only new price listed, at Best Buy as of November 7, 2026. King-size weighted blankets often cost more, so it is low for the size, but there is no second store to compare against.
