I was previously unaware of the concept of a mattress in a box. Upon visiting the Wayfair store, I had the opportunity to examine the mattress, having seen it advertised online. We proceeded to order it through the website due to the complimentary delivery service. It subsequently arrived packaged within a box. ItIt was quite heavy, so you will require assistance from another person to move it to its intended location. We have unraveled it, and as less than 24 hours have passed since then, this is its current appearance. Therefore, I will likely wait another 24 hours before placing it on the bed to ensure it has reached its maximum fullness. However, considering the price, we are quite satisfied with the purchase so far, and I will likely provide a follow-up review later.. Sabrina. Atlanta, GA. Sat Sep 12 2026

The photos were before it puffed up to its full size! I absolutely think for the price this mattress is great. I like a firmer mattress but also I know that over time it will eventually get less firm like the brand new bed it is and it will still be comfortable!
