Very quick & easy. Rowdy was knowledgeable when I told him what I was looking for. Jay was very helpful w hen I came back to purchase & the two delivery guys, Rowdy & I apologize I didn’t get the other one’s name but both were friendly & very efficient in moving the old one out & bringing in the new one. This was my second purchase with New Braunfels Mattress & I will purchase there again. Highly recommend!!
