If you’ve bought a mattress from Costco you may want to give it a good look over. Manufacturer FXI is recalling the popular Novaform ComfortGrande 14-inch and Novaform DreamAway 8-inch mattresses that have been sold this year. The problem is mold. There have been over 500 reports of mold and it’s believed the items were exposed to water for long periods of time… which means even more mold. Costco is reaching out to customers who bought the mattresses.
