  • Value priced bed frame, fairly easy to assemble.
Color: 14 Inch Size: Queen
Well made, assembly directions were "OK" and I completed the assembly by myself, approx. 2 hours. Tools provided - but a socket wrench makes it much easier to assemble! Sturdy, no squeaks, looks nice in the bedroom. I added a "bunky board" under my mattress to prevent sagging (about $80).

  • Great frame
Color: 20 Inch Size: King
Good value. Appears sturdy. Son uses it with king mattress. Last frame broke. Had two years. He's a big kid. 6' 3" weighs around 350. So far so good. Hope to get more than two years. Easy to assemble. No squeaks.

  • Solid and Quiet Frame
Color: 14 Inch Size: King
Great quality, solid, no sqeeks so far. Got 14" to go with 13" tempurpedic and height is good compromise for me at 6'2 & wife at 5'4. Slats about 5" apart seemed a little much so got mat for top.

  • Solid metal sturdy frame
Color: 14 Inch Size: Twin XL
Very solid frame, this is our second frame off Amazon the first wobbled and was not solid sturdy in anyway so it went back. This one was easy to build and came with extra parts just in case and the frame just feels solid no wobbles no noises just a solid base bed frame. Very happy with it and night and day vs the other one we returned from a different manufacturer. ... show more
