The mattress is very comfortable, upgrade from our old mattress. Let’s talk about the box spring, it is NOT a box spring at all. Wayfair needs to remove the wording “box spring”. It arrived 2 days before my mattress did giving us time to build it. We purchased a king set so there is roughly 28 wood slats with pre drilled holes. It took my husband and I 30 minutes to put together, fairly easy. Then you place it in a bag, but it’s not really a bag it’s like a fitted sheet to cover the wood. This was a bit misleading but I will say it does work, and is very sturdy.
