Easy to assemble but it is so creaky! I tried tightening it every time it would creak again but the logistics behind that are just a pain in the butt. Investing in the foundation from the place I purchased my mattress instead. My friend recommended this to me and she has no issues with noise so maybe I got a defect?

Whoever made this is a genius. We both drive small cars and box springs were SO expensive before even finding a way to get it home. This showed up in a nice little box, it was easy to assemble and our king size mattress is sitting comfortably! Plus, for the future it will be super easy to move. Freaking love this thing and will never buy a wooden box spring again

Product wasn't bad. Missing some end caps which helps with stability/durability. There was no customer service number to contact them for possible replace parts.

I recently purchased the Zinus 7 Inch Metal Smart Box Spring for my queen size bed and I must say, I am quite impressed with this product. The assembly was quick and easy - I was able to set it up in just a matter of minutes, without any tools. The metal frame is sturdy and strong, and it provides excellent support for my mattress. I also appreciate the fact that this box spring is only 7 inches high, which makes it the perfect height for my bed. It's not too high, nor too low - just the right height for comfortable sleeping. The design of this box spring is quite smart, too. The metal frame is well-crafted and the corners are reinforced to prevent any wobbling or shaking. The overall build quality of this product is top-notch and I am confident that it will last me for many years to come. The only reason I am not giving this product a perfect 5-star rating is that it does make a slight creaking sound when I move around in bed. However, this is not a major issue and it does not affect the overall performance of the box spring. Overall, I would highly recommend the Zinus 7 Inch Metal Smart Box Spring to anyone who is looking for a reliable and easy-to-assemble mattress foundation. It's a great value for the price, and it has exceeded my expectations in terms of quality and durability.
