    • Emoda 5 inch Twin Box Spring

The Emoda 5 inch Twin Box Spring is a fantastic box spring. It comes in a little box and you do have to assemble it. The appearance of this box spring is the same as traditional wood box springs. Did I mention this box spring is metal? It is very durable there is not any noise at all compared to traditional wood box springs. The one I purchased has a low profile ( 5") but you can get the desired height that you want. There are various heights to choose from. There were not any missing parts and it was quite easy to assemble. Be careful when installing the metal slats that distribute weight across the box spring some have to be tapped quite hard to insert them. I recommend using a socket and ratchet as well as an Allen set for installation. With all the nuts and bolts, this will save you some time and head aches. The provided tools will work, but it is a very slow process tightening everything. This is a very good purchase for the money, I would recommend this product or purchase it again if I needed too. ... show more

    • Great Box Spring — Sturdy, Easy to Assemble
Size: Twin Style: 5 Inch
I ordered this twin box spring to go with my new Firm-Gold mattress, and so far, I’m very happy with it! I wanted everything brand new since I was finally replacing my old bed setup, and this box spring was a great choice. It came well-packaged, with all the parts neatly organized. Assembly was straightforward — I took my time while my mattress was decompressing and had it fully put together in under an hour. Once assembled, it felt sturdy and stable right away. I didn’t notice any bending, creaking, or weak spots. The metal pieces fit together tightly, and I added a few zip ties where the metal meets metal, just to make sure there was zero movement or noise — and it’s been completely silent ever since. The height is just right for now. I paired it with a 14” mattress, and while the setup sits a little lower than I prefer, that’s more about my frame being short. A set of bed risers will easily fix that later. I also used some leftover plywood cut to size on top of the box spring before placing the mattress, to make sure the surface was perfectly flat (memory foam can sag if not fully supported). That setup has worked perfectly so far. Overall, I’m impressed — this box spring feels strong, supportive, and well-built. It was affordable, easy to assemble, and made a huge difference in how solid my new bed feels. If you’re looking for a sturdy foundation without spending a fortune, this one’s a great pick. Ps I love that the box spring cover is a fitted sheet deal so if I want (which I probably will a few times a year) I can wash it to make the room feel complete fresh. ... show more

Size: Queen Style: 5 Inch
Review Image by Charm
Easy to assemble. Not the traditional box spring with all the stuffing and coils inside so I dont think it will be noisy. I gave 4 stars because the material that covers the box spring is very thin; just by me picking it up and carrying it to the bedroom it ripped on the corners. I like it because its sturdy and gives my mattress the support it needs. I sleep good! ... show more

So happy this fit perfectly! It does feel affordable, and I am worried about stability on the frame, but I’ll do my best to be careful! Building it took 2 hours and I did it by myself. Will update if there’s any issues. I laid on it and it felt better than with no box at all. I needed something to last me 6mos to a year since I’m not ready to buy a new mattress yet. ... show more

    • Functional but noisy
Size: Queen Style: 5 Inch
Easy to assemble and seems sturdy. It was quiet at first but after 6 months it makes a noise for every small movement which gets annoying.
