Amazon Basics Smart Box Spring Bed Base, 5-Inch Height Mattress Foundation, Tool-Free Easy Assembly, Queen, 79"L x 59.5"W x 5"H, White

What a great deal! This literally took me 17 minutes to assemble and zip the cover on. I didn't need any tools but did use a rubber mallet to make sure everything was seated.Amazing RTA engineering. Perfect for what I needed and apprars to be of great quality.

Love this boxspring, hubs put it together in under 20 minutes, and the cover was very easy to put on as the zipper goes entirely around the cover, no struggle at all, the price is unbelievably low, we bought the full size for just under $113, also purchased a full sized mattress on Amazon for just under $180 the mattress stores prices began at $900 for a set, just could not be comfortable paying that high.

My mattress was giving me back pain after a night's rest and after testing with the mattress on the floor I figured it was due to my bed frame's slats not supporting it well enough. I bought this box spring to better support my mattress and firm it up, and it's done just that.Installation-wise, Directions are simple to follow. Frame is easy to build out. The cover is designed to perfectly fit the frame, so it will take a lot of pulling and repositioning to zip it on.Now a week-in, and my back pain is gone. Box springs do make a difference and I recommend Amazon basics for its brand name and quality.

Missing a part. Only option is to return. This piece is huge and too much of a hassle to return.Edit: do better than me. lol. Screws were with the cover not in the box like I was expecting.

These are easy to put together and are very sturdy.

This box spring was amazing. Easy to put together. I bought it from the warehouse at Amazon. No slats were missing, nothing was bent. The two screws, slats and frame were in the box.This was a twin. My old box spring was chintzy and I really needed a new one.

Quality frame. My husband had the frame together in about 7 minutes. The hardest part was putting the zippered cover around the frame. Solid, makes absolutely no noise at all and supports a pillow top king size mattress perfectly. Really recommend this.

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.
