EASY INSTALLATION!I’ve purchased dressers, nightstands, tv stands, desks and more from Walmart. I must say this was the EASIEST thing I have EVER put together. It took me literally 30 minutes! No tools required, every thing pops/slides into slots. I wish everything that I ordered that came in a box was this easy! If you’re on the fence about purchasing, don’t be. BUY IT NOW!

Great box springJust received our new 5” King box spring and assembled the entire thing in less than 10 mins. The cover for it went on easily and it fits inside our bed frame perfectly. The mattress feels very solid and there is absolutely no sound from it. Definitely worth the sale price!

Omg.. on a budget.. get this!! HurryI seen this a month or two ago when I was shopping for box springs for my bed. I didn’t need one since it’s a platform canopy bed but with just the mattress, it’s a little low and I wanted to climb my petite self into bed so I started looking. For something “optional”, I didn’t want to break the bank. Just bought a house as a single mom (whoo hoo..thank my creator) and am on a budget. I seen it for $100 originally for a queen size and although that was a great price, I was still skeptical because reviews were limited and mixed. Last week, looking for something else, I seen it in my save for later list on rollback for $70.00!!! I jumped at it. This has to be one of the best budget items made. I’m serious. I’m 5’3, 120 soaking wet and I put this together on my lonesome in 30-40 mins (I took a break, don’t judge me lol). The construction of it feels sturdy. No damage to the parts when unboxed. The cover that you zip over it fit just right. I’m so impressed. You should try this if you need a box frame for yourself or family member at a very low cost and it does the same thing as a traditional box spring except metal and you can take the cover off and wash it. Walmart needs to bring back the Spark program too!

Easy to AssembleAmazed at how easy it is to assemble. I was preparing for a 2-4 hrs assembling then when I opened it took less than 10 mins to assemble.
I also like the covering they provided for spring..
I like this product because they took into account of time to assemble and look of product.
Earlier I brought desk from IK**** it took 2 days to assemble it.

HONEST TRUTH, NON BELIEVER IN REVIEWS!i NEVER believe any of the reviews UNTIL i buy myself. and i want to say its so worth it! it is definitely sturdy and you can do it by yourself. i have the spa mattress that i put on this and it honestly feels GREAT but the only thing i dont like is its metal and i dislike it being on the floor. BUT i dont like the metal because i am not sure what kind of frame i can put it on 😅 other than that. i LOVE it. definitely worth the price.. wish i had plastic to cover it with as well so it wasnt getting dirty. which i can buy separately but who wants to do that haha. BUY IT!! the wooden ones break to fast. it was a simple way t put together, also DONT use a hammer, just your palm of your hand. also it was dusty, it looked like rust BUT i didnt see any rust on them. 💯💯!BUY IT!💯💯

A monkey such as myself could put this together!!Easiest thing i have ever put together! It was great not needing hubby or any tools for once! Everything tightly clicks in and zips up. Super sturdy, and really great price! I never write reviews but this was pretty sweet i couldn’t pass up not letting others know esp because i did read reviews before purchasing this time. 10/10 would recommend!

Weird size – doesn’t seem to be adjustable.Price was amazing, $79 shipped with tax but for some reason its smaller than my queen bed from. Its also smaller than my mattress. The box says queen and my order says queen but its a few inches short on all sides. Looks like a sandwich with more bread than the meat.

Short comingsThe mattress cover does not fit! Way too short to zip up so the rails are exposed. Otherwise dummy proof assembly was quick and fast. Serves the purpose price was appropriate for the quality.

Sent used item when I ordered a new box springI received the item and the box was ripped and re-taped. The item was used and return and Walmart just sent me this item. I am very disappointed when I purchased a new item. Every time I order from Walmart, the process is never easy. There is always something wrong with the item or the process.

There’s rust on he metal, and there’s small scratches as if they item was used. I love these box springs I have one for my daughter but it makes me uneasy that there’s rust on this one. My daughters didn’t have it
