Terrible support, but an easy fix. We purchased this about a year ago and ended up unnecessarily replacing our mattress as a result. Several months after purchasing this, I started having back aches and very poor sleep patterns. I thought it was due to our older mattress, so we spent $1400 on a new mattress. After six months on the new mattress, I started having problems again. When I pulled off the mattress to check the support of the box spring, I realized the problem. The wood slats easily flexed downward and did not provide enough support. Thankfully, I came up with an easy fix. I placed a six-foot section of 2x4 under each side of the boxspring and now it provides the support I need for a good night's sleep. My plans to go to a chiropractor were no longer necessary and I'm sleeping through the night once again.

I previously bought a regular box spring and with the thicker mattress that came with it, it was so high I had difficulty getting in bed. These box springs are fabulous. They require some assembly, but they are very easy to put together and in minutes, it was on the frame, the mattress was on and the bed made!

Terrific box spring, easy to put together, I bought a full and a queen size to lower the height of my beds. I got each one put together by myself in less than an hour each. Very sturdy and now I realize how worn my 20+ year old springs were. My 1 yr old mattress feels new again

This is the best fitting and easiest mattress to put together ever. If I could give it more STARS I would. The easiest way to put the cover on was to put the mattress frame on the bed first. Lift up the frame adding the bottom of the pad all the way around. Put the slats on and zip away. You should have no problem when zippering it.

I ordered this for my mother. She needed something low platform to go with her new mattress so it wasn’t so tall. This product comes in a box and my husband put it together very easily and fast then we both slid the zip up cover over it. It’s very well made in my opinion and we was very satisfied with the product.

Frame was very easy to assemble. Had to do some adjusting to my be frame as the box spring was exactly the same width as the outer edge of the bed frame. But, the bed frame is 60 plus years old so it wasn't a surprise. Works good. Bought it to replace the standard height box spring which made the bed too high and difficult to get onto..

We were debating on whether we had made a mistake buying a king size mattress. It always seemed uneven and had an uncomfortable ridge in the middle as the furniture store installed it on two twin box springs. Additionally, it was so high it was difficult to get in and out of. This Zinus low profile box spring solves all our comfort issues and the Sam's price was 30-50% less than other stores. We highly recommend this purchase.

We love this support frame. We purchased a new mattress and got rid of our old 8” high twin box springs and bought slats for our new mattress. What a disaster. The bed was much too low and sagged in the middle to the point I called the manufacturer to complain about the mattress quality. After discussing my situation with the manufacturer, I realized we needed a low profile frame. I found this frame at Sam’s for so much less than anywhere else. We ordered it, it was here in just a couple of days. It was very easy to put together and it perfect for our new mattress. We are sleeping great again. A good foundation is necessary for everything in life!

Bought this to use as a stand for an 8 inch futon I was using for a guest bed. Now I can have it all set up to use instead of having it rolled up in the corner. It arrived promptly and was easy to assemble. Would be easier for two people but was OK by myself. Followed one comment about putting the slats in after putting on the cover and it worked much better because the frame is heavy for one person to hold and move around the cover with the slats in.

Very happy with fit and delivery
