12 Inch King Box Spring

This heavy-duty box spring delivers a clean, practical design to provide a reliable foundation for your mattress setup.

Perfect for my 14” tall mattress that I also received from Wayfair! Previously, I ordered an extremely expensive mattress and was so disappointed with it, but already had the bedtime that needed height-so this was a perfect addition! It took 30 seconds to unfold, set in the frame, and zip up the cover. It’s super heavy duty and my heavy mattress doesn’t sag at all. I would certainly recommend this product if your mattress needs support and a little boost!. Crystal. Springfield, IL. Wed Oct 14 2026

I've never assembled a box spring before, and it seems sturdy for this price point. I ordered the twin size, and was able to put it together by myself except for one step - I wanted to stretch the slats all the way to the edge of the recessed area so the straps would be taut. Consider wearing gloves for assembly, lots of splintery wood. My only suggestion for the seller is they should put an extra of each of the smaller hardware bits just in case they got lost.
