Perfect for my Toddler’s Room!
I am so happy with this 7-inch full-size box spring I purchased for my toddler’s room! It was incredibly easy to put together—seriously, I did it all by myself in no time. The instructions were clear, and all the pieces were well-organized, making assembly an easy and convenient.Once it was set up, it looked fantastic in her room! The height is just right for her mattress, and it gives the bed a clean, polished look. It’s sturdy and provides great support, so I feel confident that it’s going to hold up despite crazy toddler shenanigans. I have even slept on it a handful of times and have been impressed by the comfort her bed offers on this boxspring.Overall, I’m super impressed with both the quality and the ease of setup, especially for the affordable price. I highly recommend this box spring for any room.

Very Nice & Easy to install- But Frame came Bent.
Omg when I say that when I saw you could buy a box spring on Amazon- I’m not going to lie I felt dumb for not looking sooner. Had a bed bug infestation for the past year and finally convinced my dad it was a legit problem. The start of it was from when my sister came over to hang out and brought them over from her house. They made home in my old box spring. Fortunately, I was able to remove the old full bed set and EASILY put this bad boy together, less than 15 minutes too! No tools. But there was one problem, the left hand bottom leg to the bottom base frame where the screw / pin slid into the joint to connect the bottom piece of the frame was bent ! I wasn’t able to screw the little screw in AT ALL! so I had to take some steel stick and hope for the best. Already burned my other bed in the process of getting this one build and taken out. Couldn’t go back. Wouldn’t recommend getting this without steel stick JUSSSST incase. It’s a very nice box spring and the cover was difficult to put on too- I had to have help from my fiance, but other than that – beyond worth the 100$!! I would say go for it.

Great frame
Easy to assemble, very sturdy and loved it.

Failed completely at 4 months. weak metal, small poor spot welds.
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.
