Whoever came up with this idea for the easy assembly boxspring is a genius. Box springs are one of the hardest things to move since they do not bend in are difficult to get up a stairwell. And this being made of metal is more sturdy than a wooden framed one this will be very easy to disassemble and fold up when I move and transport to the next home.  I wish I thought of this myself.  Pure genius!

Easy Assembly Box Spring

walmart.com

This was so easy to assemble. It looks intimidating when you first unbox it but it's nothing more than just snapping parts together. No tools needed! I ordered a king size and assembled this in less than 10 mins. The cover is easy just unzip all the way and tuck in box spring then re-zip. It's very sturdy not squeaking or noises and is supporting my hybrid mattress nicely

Easy!

Bought a new mattress from Costco and bed frame from Macy's thinking since the mattress is 14 in I wouldn't need a box spring. Once everything was delivered I quickly realized we needed the box spring. Did a quick google search and found this highly rated item. I placed the order and it was delivered in less than 48 hours. We quickly assembled it in about 15 mind and now our new bed is finally complete, I couldn't be more pleased with this purchase.

A quick 15 minute assemble with no tools

Super easy to put together. Box is large (long but maybe a foot wide). Put it together in about 10 minutes. No tools required. Slip cover for the frame was easy to get on and fits perfectly. I got a king size box spring and have already recommended it to friends. Would never know it was metal and i had to put it together. Would purchase another if I needed one.

Great product.

Only slightly hesitant to order an assemble yourself box spring but it was great.  Extremely well packaged, designed and engineered.  Easy to assemble.  I actually think the quality is better than the pre-made ones in mattress stores.  The covering was well made versus the flimsy stuff that tears on the pre-made ones.

Top Notch Product and Design

If you don't have one you better make plans to grab it! My mattress sleeps so much better with this one than the old style coil wood boxspring.. I changed all three bedrooms to the metal !!! Easy to assemble and very sturdy I have a 16 inch double pillow top mattress.. so much better with the metal

Excellent! I love it

I have arthritis in my feet and knees.  We actually bought this to raise the height of our bed to make it easier for me to stand up. 
We were told when we bought our very expensive memory foam mattress 2 years ago that it didn't require a box spring.  This has brought new memory to our mattress!   
I am amazed at how comfortable my mattress is now!  I can actually wake up without aches and pains!

I hate the fact that I was under the assumption it came with the feet.. that was a disappointment but I shouldve known by that teenie tiny writing on the last slide it wasn't included

I've had it for 7 months. I was laying in bed the other night and suddenly one side of the mattress collapsed. I pulled the mattress up and the whole side of the box spring fell out of the slots the bars were in. Turns out, it appears that one side, the weld is starting to come apart. So now none of the bars match back up to the other side.

Need a replacement

I'll only recommend this iron rod box spring if it's for a kid new king size bed cause this box spring it's not for adults at all unless they weigh 90 lbs - 150 lbs not for 200 lbs - 400 lbs
