Customer Reviews
Customer Review: “Many reviews mention the frame allows mattress slip. This may be in part because exactly one half of the bed slats have non slip tape on them (5 out of 10 of them). You can put all the non slip slats on the end you expect to slip most, or alternate between the two types. But there’s another cheap so”
Customer Review: “This is by far the best bed frame ive ever bought. Im a man of modest budget and income, so ive not purchased many bed frames. But this one is by far the best ive had. Super easy to assemble to 1 person, took 45 minutes with the help of my 6 month old pup. Its nice and tall, has plenty of room under”

Customer Review: “Can’t wait to use and so happy they sell these because once you move your bed these break off. My slates slip out all over so can’t wait to get these things attached again.”
