    Easy to put together
  

*by J***A on Reviewed in the United States on September 18, 2023*

Bought this for my son’s twin bed. We went from a loft bed and needed a box spring so went with this one, so glad we did! It’s sturdy enough that I feel like if he jumps on his bed it won’t break or anything like wooden box springs can. Super easy to put it together, took me about 20 mins and that was with two kids crawling all over me. The screws were easy to put in and it came with three tools that allow you to pick what’s easiest for you. The directions are pretty simple pictures that show which part goes to which, but it doesn’t take a lot to figure it out. It’s not heavy for meting all metal and the top cover fits snug, it also fits perfecting it a twin frame. There’s also no creak noise when my son got into bed so that’s nice too. Oh and I didn’t have to wash the cover because there was no smell so that was also convenient! Over all 10/10! Might even get one for my cali king, now that I know it’s easy to put together and way more sturdy then the wooden box springs. Definitely going to recommend!

    Easy to assemble!!
  

*by A***Z on Reviewed in the United States on September 12, 2023*

I was hesitant to buy this box spring instead of an actual wooden one. I love it!!!Easy to assemble if you purchase the upgraded one that you can just pop in. I bought two: one twin size and one full size. For the twin size it took me 10mins to assemble, yes, 10mins. I did it alone, so ladies, you don’t need a man to help you! The full size took me 22mins, also alone. The full size does have some screws involved but not many. Both feel sturdy, are not heavy and the cover comes right off so it can be washed. Directions are so simple and easy to follow! Highly recommend it!!!

    100% A Must
  

*by M***N on Reviewed in the United States on September 6, 2023*

I would’ve gave this product 5 stars, but I spent 10 minutes trying to place the middle vertical bar that stated UP. However, the yellow sticker on the bar stated up when it should’ve been flipped. Someone was sleeping on the job, but overall the product appears super sturdy and durable! The top part of the middle bars also had a weather strip/nonslip material going on so that the bars weren’t metal rubbing against metal and I loved that feature. The directions were super easy to follow too and I love the fitted box spring protector that was included. I would recommend this product and I would even by it for myself if I didn’t already have one!
