Husband was leery of purchasing a mattress in a box but I’ve bought 3 now as we just moved and this is my favorite by far. We’ve been sleeping on it on the floor waiting for our new bed frame to arrive and you cannot tell you’re sleeping on the floor. It shipped quickly, expanded well and didn’t have a smell of any sorry. My husband that previously mentioned he liked medium firmness on a mattress informed me that he loved our mattress. It’s definitely more firm than plush but not so firm it doesn’t move but on the flip side it’s not so soft that you sink to the bottom/floor. It molds around you very nicely. Would definitely recommend and purchase again in the future!
