Received an email a day or two ago saying they will be raising prices on all their mattresses on June 1.
The only price they confirmed was the Queen size increasing from $600 to $750. That's 25%, so not an insignificant increase.
Still a good price for a great mattress, but if you were planning on getting one in the next few months to a year, you should probably do it in the next week.
