Question: Does this require a box spring?
Document: We ordered this as an inexpensive bedframe for a spare bedroom. I don't know who measured this, but the frame is a full 3&#34; shorter than either our twin size mattress or box spring. We measured, because we couldn't believe it. Mattress and box spring are both basic Sealy models. I'd love to know who the people are who liked this frame; I can only assume they reviewed it before actually putting a mattress on it.
Very cute and girlie
Still felt flimsy and the base didn't fit onto the head- and foot-boards well. The slats didn't fit well together and the head board was tilted backwards even without anything on it. Overall a piece of junk. Needless to say I have already put in the refund. Why is there not a 0 star rating option?
My youngest loves how it has the design and not so high up, she loves it and so do I.
My husband put this together in eight minutes, including uncrating it. It comes in 6 pieces:  headboard, foot board, 2 halves of the horizontal frame, and two posts. You need a hammer or mallot to secure the head and foot boards to the horizontal frames, via dropping them into slots. The only other assembly needed is to secure the four provided screws with the 4 provided nuts. The completed frame is sturdy; no squeaks, rattles, or movement.
My daughters had used bunk beds since the time they were both out of cribs, and when we were finally able to give them their own rooms, we separated the bunk beds, giving each child their own portion. After a bunch of wear and tear on the old (separated) bunk beds, they broke. I allowed my 10 year old daughter to pick out her new bed, and this was the frame that she chose.
I wanted to purchase a relatively temporary bed for my 5 year old daughter. Something that would last about 2-3 years. I figured I would get something of low to mid quality. My expectations were realized.Keep in mind that I bought another twin bed (DHP Bali Metal Bed) for my son at the same time for about the same price. The DHP bed is of far better quality.
I ordered two of these for my girls and they love them. They were easy to assemble, and are very stable. Great space underneath for under bed storage.
I ordered this bed frame for my 7 years old boy. I had no big expectations, but after assembling the bed, it looks really nice. The bed is sturdy, since it lays on four legs and two posts in the middle. I am sure it will last many years. In overall, as a quality and price, this was the best bed for me.
I bought this bed for my five year old and it's perfect for her. Was easy to built and sturdy!! !
Answer: Not necessarily,.. if the person sleeping on it is not very heavy.  I bought a good quality mattress and it seems fine for my daughter who is 5 years old. A bigger person/heavier might need a box spring.  Hope this helps.
