Hercules 8 Inch High Profile Foundation Mattress Box Spring Replacement for King Size Beds - Premium Support for Back Pain Relief & Enhanced Sleep Comfort, Perfect for Master Bedrooms & Guest Rooms

This platform does a great job for what it is -- basically a wooden pallet that supports the mattress, you could build it yourself but why would you want to? this comes very well packaged, is pre-cut and very easy to assemble. I started looking for a new foundation because my one year old mattress had what I thought were body impressions in it but after looking at this to try to find a way to lower the bed height (it was far to tall anyway) I felt the foundation that was under the mattress- the one that came with the mattress set, it has wood frame around it with soft interior so what I was feeling was the two wooden pieces in the middle, it is a king with two piece foundation. If you put your hand under the mattress and press down, it is very easy to feel the give in the middle of the original foundation and the frame around it -- a VERY poor design and not at all supportive of the mattress so the 'body impressions I thought I was feeling was just 'give' in the foundationAfter putting this foundation under it -- I won't go into assembly as there is another very good review with pictures above but it took me about an hour including adding 8 additional 1x2x6s from lowes ($1.10 each) just for fun - the ones that come with it were probably enough to do the job as we are not large people. The only thing I will recommend is a deep 1/2 inch socket for the bolts - its much faster than using the included wrench and careful use of an electric drill or screwdriver for the screws that go in the slats - just be careful it is pine (I think) so it is soft wood- just be careful not to overdo it. The biggest challenge to assembly is putting the fabric cover over the assembled frame (it is a very tight fit) but looks great when finished. The bed feels much better, body impressions / dips in the sides are gone and the bed is about 5 inches closer to the ground than it was, a much better height; so for us, it was worth the money. Oh and for those who've asked, there is no creaking or noise from the foundation after it was assembled and placed on a solid metal bed frame. Do note the height, this is much shorter than a 'normal' foundation- for example, the one that came with the mattress originally was 9 inches tall and this is 4 inches tall so my bed is now about 5 inches lower than it was so measure to make sure this is what you want.
