Zinus 4" Metal Box Spring with Wood Slats, Mattress Foundation, Full

Overall, I highly recommend if you are getting a memory foam mattress so there is uniform support at the mattress base since that mattress is going flex and deform. Very easy to put together, and the supplier pre-packaged the hardware with extra bolts, which was a nice touch. The only thing is that the box spring liked to slide on top of the mattress frame since they are both metal and I put my frame on a slope to address acid reflux. ( Even without slope, you are going to have sliding on metal-to-metal contact.). I am using elastic ties to keep the two together, but will probably get Velcro to put on each to keep them together - not a lot of force is required: just enough to prevent slide. Something to consider if you have a metal mattress stand.

Honestly way better than any others I've seen ! Definitely would buy again and have recommended to my family and friends !
