Highly Recommend! This is a very comfortable mattress and can be used with or without a box Spring. Mattress is more on the firm side and holds its shape nicely. My mattress is on a box spring with a gel topper because I prefer a high bed but mattress could be used alone. Mattress would also work well with an adjustable base. Before using be sure to let it inflate the full amount of time in order for it to fully expand.
