  • Easy to Assemble, Very Sturdy Boxspring with Added Advantage of Disassembly, If Needed
Size: Full Color: 9 Inch
Initially, I was skeptical of ordering a full-size boxspring from Amazon, but should it not meet my standards, returning would be easy. My spouse found it, so I didn’t read the description, but I assumed it would be a typical boxspring – wooden construction with fabric covering. She didn't mention that it said, "Easy Assembly." I was surprised when she said there was no extra shipping or delivery charge. Well, was I surprised when a box about 9” x 9” x 30” marked “Heavy” was left on my porch. When assembled, it’s a steel spaceframe with a fabric cover. While there are numerous metal pieces and a bag of screws, it assembles quickly. The outer skeleton is assembled first using the supplied screws and hex key, and the crossbars are simply snapped into place. I’m very handy, but I was surprised at how quickly it assembled. The cover slips on easily and the elastic corner straps hold it in place. As I was assembling it, I was struck with the thought that this makes moving easy – pull of the cover and disassemble the spaceframe. No bulky boxspring with which to contend. Assembled size is just over 53" wide (about 1" less than standard full-size mattress width) but is almost 75" in length (standard full-size mattress length). The dimensional differences surprised me until I thought about it. The slightly reduced width may be intended to prevent running your shin into the metal edge. It's not sharp but might be a little painful if directly bumped. Assembled, it is sturdy, very sturdy. It was priced at less than half the price of a traditional boxspring on sale at a local store. I ran into an easily solved issue of placing it on a metal bedframe. Initially, it tended to slide around just a little, but I fastened the two frames together with a few heavy-duty zip ties – no movement now. I rated it a 5-star buy for several reasons – easy to assemble, quality construction, less than half price of a traditional boxspring, thoughtful design to prevent bruises, and it can be disassembled, if desired. My view of a quality boxspring has been forever changed, and I saved a bunch of money. ... show more

  • Think it over
** UPDATE THIS 7inch frame has already broke bending right in the middle. The holds 3000lbs is a lie.** First time ever buying a box spring from Amazon and I didn’t even look at the reviews for it. Pleased to say I’m happy I bought it and it very steady. You get everything in the box it comes with and instructions. Definitely took me over 45 mins to get done being disabled I don’t get around so easy anymore. ... show more

  • Work the money!!!
Size: Queen Color: 8 Inch
I just bought these box springs for my son. It took him about 20-30 minutes to put together. He slept on them for the first time last night, he wakes up with a stiff back every morning. He said these box springs are a 10/10. His back felt great this morning. Very worth the money to try.

  • Please refund. I will not be able to return or replace in time.
One central piece came damaged. Not by shipping. The box and packaging were amazing. The idea and price were great but now I cannot set it up at all and I am behind in my project.

  • Squeaky box spring
Easy to assemble and gets the job done. It feels sturdy overall, but unfortunately it is pretty squeaky. For the price, it’s decent, but I wish it were quieter.

  • Surprisingly Sturdy & Easy to assemble

Surprisingly not that hard to assemble and once together very sturdy. Way better than paying $350 for a press wood box spring from a mattress store
