      This platform bed frame is pretty cool, it folds up when moving not bulky at all. It says you don't need a box springs under you mattress, and that is probably true, but you have to buy a good mattress.

      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.

      Verified Purchase

      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.

      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

      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

      I purchased this frame for a guest bedroom. The frame comes in a box where the 2 halves easily unfold and link together to fit a king size mattress. I was able to do this by myself very easily. The quality of the frame is very thick, high gauge steel...much better than what I was expecting. Once setup, the height of the bed is perfect, not low at all and the frame is easily hidden by a regular bed skirt. I would highly recommend this for anyone looking for a solid bed frame for less than half the cost of buying box springs from the store. Great value! Great item.

    • I just bought the Sleep Sync Posture Support Eastern King 14-inch Platform Bed Frame...what is the headboard bracket's item number and where can I buy it?

      • I bought mine from overstock. Item 14018901. I haven't used them yet though. $**

    • This frame says it is 14 inches high. So does that mean if you put a mattress on top it will sit very low?

      • I used this frame for three of our King beds. I used the box spring and the mattress so it is very high which I like with the frame. My son uses this frame with just his mattress and he loves it. It ends up being just a little lower than the regular bed and box springs. Hope this helps.

      • @OstkUser46822 Thank you it does! We are getting the 14"memory foam mattress and when I held up a tape measure for 28" total next to our current bed which has frame, box spring, and pillow-top mattress it is only 27.5" so we will gain a half inch. It will work perfectly!

    • 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.
