  • Easy to assemble & sturdy
Color: 6 Inch Size: King
This boxspring was a lifesaver. I bought my bed and loved it, but I hated that it was so low and did not come with a boxspring. Luckily, the boxspring, save me from having to return the bed. It was easy to put together and it keeps my mattress in place, and is sturdy and durable.

  • Perfect
Color: 2 Inch Size: King
I have a small dog that sleeps with me so I was looking for a base that offered support but wouldn’t raise my bed and this has been the perfect addition. I put it together and placed on my bed by myself. Honestly so happy! Good value for your money, it is a perfect fit for my kind bed, it was easy to assemble. ... show more

  • Almost perfect.
Color: 6 Inch Size: Queen
The basic set up was easy, maybe 16 screws and locknuts. I would have given 5 stars, but cover is a complete fail. It has no bottom cover, so you will have all framework collecting dust. Not good.

  • Lowered bed for elderly
Color: 2 Inch Size: Full
Current box spring was lifting mattress too high for 90 yo to easily sit without a boost. Easy to put together. I built the frame outside and put the slats on inside. Very sturdy.

  • Does not fit!
Color: 7 Inch Size: Queen
I bought a queen box spring and it does not fit! It was easy enough to assemble, but once I put it together and went to put it on the bed frame, it was too long! I am quite disappointed to say the least.

  • Replaced 9" traditional boxspring to make getting into bed easier
Color: 2 Inch Size: Queen
After hip replacement surgery my 89 year old mom has a difficult time getting into bed even with the aid of a bed cane. The only alternative was to lower the height of her traditional 9"boxspring. This sturdy, perfectly fitting 2" boxspring lowered the height 7 creating the perfect solution.
