So far, so great
We ordered a queen mattress & frame about two weeks ago. Both were delivered within less than a week. So far, we're very happy with products. The frame seems stable & well-anchored to floor even during "sporting" activities, & we love the almost proactive support & comfort the mattress provides. It's been a great relief for my chronic back pain. Can't speak to durability yet, but given the low price (< $1200 total for both) and painless shopping experience, if it lasts five years it's well worth it.
