Novilla 8 Inch California King Metal Box Spring - Heavy Duty Mattress Foundation with Extra Strong Support, Non-Slip & Noise-Free Design, Easy Assembly - Perfect for Bedroom, Guest Room & Dormitory Use

I never have the spring box for my bed before cause it all come with slats to support the mattress. I just received my bed frame that doesn’t come with the slats. I decided to have spring box that I get the 4 inches cause my side frame only has 5 inches. This spring box perfectly fits my bed frame as pictures shows. I love it has the cover which look more gorgeous even I can’t see it when I put my mattress in. The quality of the spring box is beyond my expectation which is really sturdy. My mattress is 12inches, so the 4inches spring box is pretty enough for my bed’s height. It look gorgeous. I really love itThe box that it came in is a nice size, not too big nor heavy. Pieces are folded together so the box is not as huge. Very easy to build and minimal amount of pieces. The diagonal pieces don't come with screws but they fit nicely in place. All the pieces fit together very easily and can be built alone. The finished product is a good looking and very sturdy bed frame. The cover was easy to put on afterwards. It looks great in the room. Pretty satisfied with the product. Overall 5 out of 5 stars would purchase again.It’s the right fit at all with the mattress, right high to seat on made me feel comfortable my feet can touch the floor, I didn’t like the one that is too high when sit on top not able to make myself comfortable. This box is twin size makes the room have more space and it’s very strong as the foundation holds. It’s a great choice, I would recommend this for friends and family as well! I would like to buy another one for guest room also, it works out for my family very well. We are happy with it.This product is very simple to set up, The components are easily connected by screws，Finally, put on the cover and it becomes a standard bedstead. However, there are no fixed screws for the horizontal support strips, which makes them easy to fall off, You have to be very careful to move it，Especially when you put on the cover in the last step, I tried it two or three times myself to make sure it wouldn't fall off. I hope this product can be improved in this respect and more fixing screws can be provided to the customer！My younger son is finally old enough to sleep by himself and he decide to sleep in my older son's room. So i bought this bed frame for him to put beside the big bed , so the boys can sleep in the same room but different bed. It is good quality and very easy to build , my son even helped me build it. I love it with the metal , and it have space under bed, so i can put some small cantainers under to save room. Good buy.This spring box made of sturdy steel, it's super easy to install, the steel frame is folded, just extend it and fix it by screw, then put each poles on from center to sides. The box spring is strong, sturdy, Amazon's selection is reliable. At first, I was thinking the cover was made smaller than the frame and I could slit the cover if I pull too hard, but I was wrong, the cover is just the right size, I tried to pull hardly and get it on to the corner of the frame, they sit on and didn't break, amazing. I'm satisfied.The delivery was a little late for a few days, but I was quite surprised after opening the package, because its assembly is really simple, it only took me ten minutes to assemble it, and it has been used for more than a week until today, The bed frame is very sturdy, there is no sound, the height is reasonable, the quality is really good, I will buy it again next timeWe had been looking at those “traditional” wood bed boxes. However, it turned out that we would not be able to move those kinds of bed boxes in because of the structure of our house. Later, one of my friends introduced this kind of bed boxes. It is totally made of metal so it is very sturdy. It needed some assembling work, but it was not hard to put it together. This choice worked well for us.
