    I am a single girl renting an apartment and I was trying to avoid the cumbersome box spring set up. I was a little worried that this would not be as good as box springs, but boy is that not the case! It comes in a box via regular carrier and I was able to slide it into my apartment myself and put it together myself (although it recommends you have a friend help you, but I like to be independent...except when it comes to auto repair and spiders). No tools needed! It is very sturdy and well made. I bought a regular mattress (queen) that fits perfectly on it. Best part is that when I need to move (inevitable) I can just fold this up and take it with me. I am THRILLED!

    Good quality, easy to set up. Provides good mattress support. The legs have an adjustable height which is nice. I went the with the regular height the legs show and have a nice look to them. I would recommend this product for anyone not wanting to spend a lot of money on a bed frame with superior quality. Who could ask for more!

    Excellent quality, quick to put together and in the future if we no longer want to use our bed as a queen size, we have the option of turning it into two twin size beds, that was a nice surprise. Very well worth the money.

    I purchased this bed frame about 3.5 years ago and have never regretted it. It's a strong bed frame that is easy to assemble and then disassemble when it's time to move. Gives good support for memory foam mattresses and is an optimal height for those with arthritis. Highly recommend and would purchase again without hesitation.

    Purchased this system to use under a foam mattress. This system was confusing to put together and was so low to the floor that we added bed risers to it. Attaching a headboard and footboard was possible, but difficult.
