      This is a great bed frame. It does exactly what it's supposed to do, support a latex mattress. We're been using it for nearly a year with absolutely no problems.

      I have had this for almost a year and it still hold up. A little squeak but some spray knocks that out. It is not bulky and easy to move around.

      I knew my bed was not a California King but I didn't know there is an "E King " as is wider than my bed but costs way too much to return so we'll live with it. But beware there is a King, California King and an E king. Be sure you know what you need.

    • Platform Bed Frame

      We absolutely love this frame. It was very easy to set up and put into use. We added the brackets so the frame would mount directly to the bed. It only took about 10 minutes from start to finish.

    • Nice added support

      I bought a new king size mattress last year and it had already started to sag down the middle. I intended to contact the manufacturer. I bought the platform frame to replace the 2 low profile box springs. It works perfectly. It provides the support I was missing and my mattress sags no more. It also fit perfectly in my platform bed. Measurements were exact

    • king platforn bed frame

      is not a posture king but is made by Boyd <same as on humble abode, only they charge more, this really messed me up because i thought is was a different one and and larger, because a king mattress actually measures 75X79, luckliy it all worked out, solid frame, only prob is skirts tent to slide on it more than a box spring and it makes it harder to change sheets and get everything tight, but otherwise am very delighted with me new king, plenty of space under for those who want storage there, ended up ordering the praga brackets and they worked out well to attach headboard to frame

    • Arrived Damaged

      Not sure what happened here. Inside a perfect, undamaged box was a very damaged bed frame. It appeared as if a previous purchaser took the bed frame out, set it up and jumped on it - bending several cross members and most wire stretchers - then returned it to Overstock for a refund? Then, I got it? Whatever - photographed it and arranged a return to Overstock as damaged. Then - out-of-stock - only a more expensive replacement :-( Bought a new frame locally for the same price. PLEASE READ THIS PART - this frame has all legs recessed in from the perimeter. This is important as the replacement frame I purchased has the center legs to the outside. Can't tell you how many times I stubbed my toes on those stupid center legs. Get this frame for that benefit alone!

    • can you attach a head board to this frame

      • There's nothing built into it to support this... it could likely be done to many/most headboards using "U" bolts if you don't mind drilling some holes.

      • Yes there are places for screws to mount a headboard.

    • I don't see the brackets for this frame. Will more be coming in, and if not, will the DuraBed brackets work?
