Amazon Basics Smart Box Spring Bed Base, 9-Inch Height Mattress Foundation, Tool-Free Easy Assembly, Strong Support, Queen, 79"L x 59.5"W x 9"H, White

Easy to put together. The only way to purchase and move a box spring. Fits perfect. Very sturdy.

Super easy to set up. Took less than 8 minutes without using instructions. Feels sturdy. All the posts go solidly in. And because of the direction of the rectangular posts, I can see how this would work better than the traditional wood frame boxsprings.

Very easy to put together. Durable and easy to move and break down if you need.

This was pretty easy to put together. Of course, mt husband put it together in less than 10 minutes without even looking at the instructions (corrections if need be.) The cover that you have to unzip and then wrangle on, did take about another 10 t0 15 minutes. I am pretty impressed with the design and build of the metal framework. There isn't much to mess up putting it together. It seems much easier and looks stronger than the other metal ones that I have tirelessly researched before deciding on this one. It is a tight fit into the metal bed frame, and I hope that helps keep everything even sturdier. I hope that this lasts. We haven't really used this as it's for the guest bedroom. I will update if there are any problems in the future.

Wow! Just wow! I had low expectations for self-assembly box springs from Amazon. I was so wrong. We ordered a king and a queen. Instructions were provided, but we hardly used them. It was pretty obvious where everything goes. It was easy to assemble them and they are well-made and sturdy.

I’ve ordered other metal box springs before and they were good but this one was the easiest thing to put together! It literally took less than 5 min to put together. The cover was also simple to put on and has a thicker fabric on the side where it would meet bed rails. Directions were very clear and seems to be sturdy. It is perfect thickness for the full size frame we have and is comfy!

2 small girls share this bed,. 1 is 120 lbs, the other is 100lbs. We purchased a new mattress and this box support 4 months ago for the existing queen frame in their room. we also were replacing the traditional spring mattress with a hybrid so we changed support style to steel slat box to give firmer coverage to the mattress design as recommended by the mattress mfr. If you look at the 3rd photo in the ad, where the steel frame is being assembled by a hand inserting 1 of the rods, you can catch an inward curve of the side of the outer rails both upper and lower edge. This true on mine as well and ended up becoming the 1st issue. the corners measured fine and went to the proper measurement for our queen base, and sit perfectly square on the bed frame, but the middle on 1 side rolls inward, narrowest was a full centimeter narrower than the corners. This got worse over time and eventually let the box slip off the frame when it began to flex the 2nd or 3rd month we had it in use (after the 30 day return had ended). I eventually remeasured, and yes it had lost several more millimeters from flexing. So I ended up bending the frame of the bed on the side to give additional support. That helped for a couple of months. yesterday, 1 corner of the bed dropped 4 inches or so from the corner to the middle of the bed, the other 3 stayed at height. one of the girls was sitting on that corner putting on her boots and it just suddenly DROPPED she said. I flipped up the mattress and removed the box cover. The upper and lower rails of the frame are pre-made with support ribs every foot or so to give it strength and maintain rigidity. 3 of the bars on the collapsed corner had broken their spot welds, and the cause of this was the premade corner joint metal had flexed and broken and you can see the weld was poor so the corner was weak and eventually gave way. This is not due to excess weight, or kids playing bounce games on the bed. It was used by 2 slender teenage sisters with a total weight of 220 lbs, the frame is rated at over 600. The only reason this happened is the welds could not withstand the on and off application of weight and flexed till they broke. since the corner holds the angle and shape integrity, once it broke the supports ribs then had to absorb the now moving rail spacing and eventually their welds cracked. Steel that is rated over 600lbs needs to be durable enough to hold 220 lbs forever, not measured to not collapse with 600 for 10 seconds and then claim "Hold 600 lbs!". Less than 225 lbs over 4 months bent it more which should not happen even if it started slightly curved, it bent more over time because the weak metal flexed stressing the weld joints till they physically cracked likely 1 at a time. It simply isnt a sturdy or high quality piece. It was curved when it arrived. I addressed that by making the frame cirve to make sure it didnt have a less supported rail on 1 side. The 2 months later the welds cracked on 1 corner. I dont even want to warranty it after seeing how it failed. , I expect the same issues will repeat. I assembled it myself, and noticed the slight curve even when I put it together. but the bed frame still had a grip on the box enough it looked like it wasnt perfect but should manage. I liked the high star rating which is why I bought it. Thousands of purchases. However I am a mechanic by trade, with a welding certification and 30 years experience. I do not want this frame again. It has inherent weaknesses in its construction quality that wont affect it for everyone when new, but will make it fail earlier than needed even if you get a better one than the defective one I apparently got. You get what you pay for. There is a reason this box support is 100 dollars cheaper than many of its competitors.

AWESOME IS AN UNDERSTATEMENT FOR THIS PRODUCT...EASY TO ASSEMBLE, SUPER STURDY, IT DOESN'T ONLY ADDS HEIGHT TO YOUR MATTRESS, IT ALSO ADDS SUPPORT...THE COVER FITS SNUGG LIKE IT WAS CAREFULLY MEASURED FOR IT, ITS NOT LIKE A "ONE FITS ALL" TYPE OF THING..

Very easy to put together and sturdy! Built it myself in 15 minutes with no issues. No tools needed. The corners screw in by hand and the slats can be pushed in easily and won’t pop out. Buy this one, you won’t be disappointed. High quality!
