Perfect for high mattresses. My original boxspring was tall so getting this one was perfect for me. I'm 4"11, so it was good to get in the bed with ease.

Seems to be good and sturdy
Easy to put together

Still loving it! Still not at all gentle on it. Still sleeps perfect and flat. Still not making any noise or sliding around. Best thing I ever bought on Amazon to date. Looking to buy another one for a queen guest bed now.

*Update*-
First review still stands! Loving this box spring. We are not gentle on it.... so, yeah it's a great buy. No regrets. Will update if anything happens that is noteworthy.

I bought traditional box springs for a new king size mattress in 4/2020. They slept funny putting a large speed bump in the middle of the mattress from head to toe. I bought a different set in 5/2021 from a different store. They were damaged during shipping and unusable. I bought this last week.... LOVE IT.

I've read all the bad reviews. I noticed a ton of those had no middle support under the bed from their bedframe, of course this item would bow, bend and break! You can use this on traditional bedframes with any type of mattress, but it doesn't mean you should. Any type of mattress- yes this is perfect for anything. Any type of bedframe- not so fast, platform would work the best- must have multiple middle supports to stay sturdy and functional. I bought this as a low profile box spring for a platform bed and it's perfect! Because it's supported 100% by my bedframe (same as laying it on the floor) there is no way this would bow or bend. Now it could still break at welds and joints, it's cheap, but I don't see that happening, could be wrong. I'll update if it does.

No squeaking, no sound at all. No sliding around. Sleeps flat and perfect. We love it!

It took my husband 10 minutes to assemble, including the unboxing and moving our mattress out of the way. It looks decent and is as described. Great price. We took a chance even after the bad reviews and it is a solid purchase we are happy with.

Affordable. Easy to install--it comes with the only tool you will need (except for a two-wheeler to move the product box after arrival--it's very heavy). Everything was 1-2-3. // My mother had difficulty getting into bed due to her age and height. This bed frame lowered that by 5 inches. There is no loss in quality versus the expensive box springs she bought at the mall store. The only noticeable difference is the wood slat in the fabric. Upon completion, it looks 'unfinished with loose fabric sticking out over the edges. Once you put the mattress back on, the seems are no longer showing. After one night's amazing sleep--this product gets a 'thumbs up,' from a grateful 90-year-old.

I bought this for a king bed that needed to be raised up about 4". I chose the metal frame that was upholstered for its soft feel, designer look and sturdiness for my guests. The wood slats that have soft material around them was a plus for the top mattress to slide over without being snagged. Very pleased and thank you for selling a 4".
