It's worth it.

It's a little firm but good the king fits me my wife and our 3 year old with plenty of room. if you need a new mattress this one's definitely worth it. definitely don't feel movement like on a traditional mattress still feel a little bit. It filled up fast we got it around noon and slept on it the same night. it never got to a full 14inch but its 13inch and on the bed frame it's good. Definitely happy with it.

Hello Darrell! Thank you for sharing your experience! We’re glad to hear the mattress fits your whole family comfortably and that you’re happy with the space and overall support. It’s great to know it expanded quickly and minimized motion compared to a traditional mattress. We appreciate your honest feedback about the firmness and height, and we’re happy to hear it’s working well for you. Thanks for choosing us, and enjoy many comfortable nights ahead!
