Not what we were expecting

We had bought two Naturally Bob's latex mattress a couple of years ago and found them to be very comfortable. When we recently ordered a new King size for the master bedroom, we didn't bother to go to the store to try it because we thought we knew what we were getting. Big mistake. New manufacturer apparently. This mattress was way too firm, even though we ordered the "Plush" model. Really bad off gassing that still persists a month after delivery. Yesterday we went to the store to find out if they had one like our older models that had a really comfortable pillow top cover on them. No luck. We are sending this one back. Should have gone to the store first but didn't expect this model to have changed so completely.
