This box spring came in a tightly packaged heavy box, undamaged. My hubby put it together and he says it was easy to assemble and the instructions were clear, but it was not needed once the pieces were laid out, as it was pretty much self-explanatory. We do recommend using power tools to speed up the assembly. We bought a king size and it seems durable - no creaking or fitment issues. We use it as a foundation for our foam mattress and it performs just fine, no sagging or any issues with it. We are pleased with this purchase and cost is affordable.
