    • Awesome
Color: 9 Inch Height Size: Queen
I ordered a metal box spring and I must say it is awesome it is quiet it was very easy to put together it comes with all the tools it took about good 20-30 minutes to assemble My son-in-law put it together I did not but it was it's of good quality and the first night on it I could sleeping on it I could tell the difference from the wooden box spring that originally came with my bed it was very quiet I did not hear the squeaking noise of the wooden box spring that loves used to hearing when I got off my bed and now I sleep so peacefully and I would recommend this project this box spring to anybody that wants a quiet night of sleep without noise or moving around in the bed with on that wooden box spring. Also it was very inexpensive so if you're looking to get a product of good quality I would recommend ordering this box spring I love it and yes I would order it again. The height of the box spring I thought maybe I had ordered the wrong height but it was perfect for my mattress it fits exactly perfect on my queen size bed I have no problems with it The labeling if the functionability of it is awesome and the metal is it's perfect it's there's nothing sticking out to poke you and there is a cover that comes with it that covers up the mattress so you don't see that it is actually metal it looks just like a mattress it has a mattress cover that goes over it and it also comes off so you can throw it in the washing machine and wash it and put it in the dryer and then put it back over the metal once it's dry. ... show more

This was a lifesaver as we could not get our box springs up our narrow steps. Easy to build. Not flimsy, stable!

    • Cuss free assembly!
Color: 9 Inch Height Size: Full
My family tends to leave the room whenever I am putting things together. At the first dropped screw or stripped bolt the profanity starts. Of course I am mad at myself but regrettably it doesn't always come across that way. I will atone for this sad trait in me for the rest of my life. So when I opened the box of this product and found no instructions the menace inside me was rising like a Balrog from the darkness. I composed myself. I laid out the pieces and realized it was pretty self explanatory. There were 3 types of screws that clearly would only go in their respective screw holes and the frame can only be put together in one position. I managed to put this together in about 20 minutes and had the mattress on top and bed made within 30 minutes. All without a bawdy sailors retort. That was until that cat threw up on the newly made bed. You can't have it all. ... show more

Easy to build. Seems sturdy so far. Some parts were not labeled, but figured it out. The only reason I am giving it three stars is because it came damaged.
