  • Excellent Box spring
Color: Queen Size: 4 Inch
Excellent Box spring funny as not springs to it, well made and lowered the bed height quite a bit. Great for seniors who have a problem getting into a high bed. Comes un-assembled but the instructions are very easy to follow. It took about a hour to complete. You will need someone with a little strength for putting the nuts tighten on the screws as it had built in washer to keep tight, so if you tighten well when you are putting togther you should never need to re tighten again. I really like this product. ... show more

  • Excellent quality, easy set up

Foundation for my bed to adjust height to get in and out of bed. It is excellent, provides good support and comfort. Was simple to set up. Thank you.

  • Easy to install, solid, does the job
Color: King Size: 4 Inch
Solid frame for my heavy hybrid mattress. It was built within 20 minutes and seems to provide adequate support for my purposes. No complaints here.

  • Nice Design, But………..
Color: Full Size: 4 Inch
This box spring is nicely designed an easy to put together. I used it with an existing bed frame (headboard, sides, &footboard) as product description said it was compatible, but is not. Mine sits recessed about 1.5 in. In frame. It should have been manufactured .5 in. smaller on both dimensions. I had remove 4 frame bolts and hammer in with a rubber mallet. There was no way it would fit with the cover on so I left as is. This would be perfect for someone just using on floor. If I had known before of the dimension problem before assembling, I would have cut parts as necessary instead. The description of this box spring should be revised to say it should be used as a standalone unit and not for existing full bed frames. Probably made in China. ... show more

  • Some assembly
Color: Full Size: 4 Inch
Took about 30 min to assemble. And tools that come with it are a lot of work. Thank goodness for having my own tools to assemble . But once assembled it is supportive, low profile and works great!

  • Fitting does not cover completely
Color: King Size: 4 Inch
The fitting does not fit completely so it does not cover the whole metal frame other then that pretty easy to assemble and very sturdy

  • Easy to put together, fit like a glove
Color: Full Size: 4 Inch
The media could not be loaded. This took me approximately 30 minutes to put together by myself. The cover only covers the top and it is snug. Also our full bed frame is slightly smaller than the box spring so the material from the cover came up a little on the sides. It's sturdy, and lightweight. My 8 year old daughter helped me lift it on to the bed frame to give you an idea of how light it is. ... show more

  • worked out really well for my needs
Color: Twin Size: 4 Inch
This box spring was the perfect "thickness" for what I needed. I wanted a box spring that wasn't too "thick", so this 4 inch box spring worked perfectly. And it wasn't too difficult to put together, I did it by myself
