    • Worth it! Highly recommend
Color: 14 Inch Size: King
Very sturdy! Hubby n I have a Combined weight of around 650lbs plus our new mattress and its holding up well. I was worried the metal would start creaking but so far not a squeak. Kind of a pain to put together so make sure you have plenty of working space but overall not terrible.

    • Well-made, but spend time before you put it together
Color: 20 Inch Size: King
Set up was a bit laborious. But the end result was very satisfying very solidly built. Make sure you follow the instructions. It says do not tighten bolts until you have it all together. Pay close attention to this or you will rue the day. It came with six plastic clips that hold the mattress in place it needs eight you can call the company, but I’ve had no luck. Six is not enough to hold the mattress in but 8 are.. ... show more

Color: 20 Inch Size: Full
Im really impressed with this frame. Set up took a while and I recruited my nephew to help. It seems quite sturdy. I have 4 of The black/yellow totes, and they fit perfectly. It was a bit of a shock to see exactly how high this setup is with my 14" mattress and I use a step stool to get into bed. I knew it would sit high but it still surprised me. I would recommend this frame ... show more

Good bed frame. Sturdy! The slats are not close enough so we had to order a bunkie board. But it's a string frame and works well for our new Big Fig mattress! πŸ‘πŸ»πŸ‘πŸ»

Love this frame. Set up took me about 30 minutes and it’s super sturdy. Between this frame and my mattress I was all in about $400 which isn’t bad at all for a queen size bed and frame.

    • Sturdy But Noisy
Color: 14 Inch Size: King
I have mixed feelings about the king bed frame I bought. On one side, the frame was relatively easy to put together. Although some of items had to be hit with a hammer to make them connect properly it all fit together nicely. It is really sturdy and stable with little to no wobble. There is ample storage underneath the bed frame which can be an issue if you have dogs that like to hide things under your bed. With that being said, at first the bed was silent and made no noise, however, after about a week of use it started making squeaky noises every-time I toss or turn in the bed. It was a little less noisy at the beginning but now the noise has become annoying. Trying to figure out why the noise and what can be done to reduce it. We are a bigger couple and this bold supports is with no problem, in addition to our big dogs. ... show more
