シモンズ ビューティレスト クイーン 9インチ レギュラーフラットファンデーション - 700810116-5050

Setting up the mattress on this 9-inch foundation was a breeze, and I love that it's specifically designed for my hybrid. The solid build gives me confidence it will last, though I wish I'd known returns aren't accepted beforehand.

I was relieved that the 9-inch foundation fit my hybrid mattress perfectly without any wobble, and the solid slats feel substantial. Assembly was surprisingly quick, taking less than 20 minutes start to finish. The only thing I’d note is that you definitely need two people to position it right.

The metal frame sits perfectly level under the mattress and didn't make a single creak when we first tested it out. Assembly took maybe twenty minutes total, and now the whole bed feels noticeably more solid than our old box spring.
