Outstanding Bed Frame
Color: 7 Inch Size: Twin
I was surprised at how quick and easy this box spring was to put together! It's very strong but not terribly heavy. Fits perfectly and worked well with the twin bed we have for our grandson. Can very highly recommend!

Good Product & Easy To Assemble
Color: 4 Inch Size: King
I bought a King and a Queen box springs. They are solid and best of all easy to assemble. It would have been a lot more difficult had I used the tools included, instead I used my tools in the picture included. Use a 10mm wrench, a impact gun with #4 Allen socket, and a rubber mallet to gently tap in the slats. ... show more

Great Product
Color: 9 Inch Size: Queen
Even though it took me some time to get it put together it is a great box spring. I love how sturdy it is even though its lightweight. Perfect for my son.

Easy to put together despite instructions!
Color: 4 Inch Size: Queen
Pretty easy to put together by my husband and the extra screws and nuts were nice. I love this concept! It fits perfectly over our bed frame and the cover over the frame is a nice touch. Well worth the money.

Easy to put together
The package is easy to open. All the parts are clearly labeled, and the instructions are clear. The frame is sturdy but light enough for one person to work with. Even the cover has long elastic straps that make it easier to put the cover onto the box's frame. We did this as a last step when positioning the box onto the bed frame, worrying that moving the box to the bed might mess up the cover. A tip: when moving the box, grab the end rails, as the others are not fastened. ... show more

Excellent product!
Color: 9 Inch Size: Queen
I had a handy man put it together for me. It fits my queen bed frame perfect. It is very strong and has felt great. I would never buy a wooden box springs again.

Exactly what I needed.
Color: 4 Inch Size: Twin
I needed a box spring in this height to use with a vintage twin bed. Because it's a spare bed, I didn't want to spend $$ or have a traditional box spring delivered. Easy to put together but I used power hand tools to speed the job along and save my hands and wrists. Sturdy, no concerns so far. Would purchase again. ... show more
