Made in the USA and excellent quality and value.
#50 My sister in Minnesota has this bed and she likes it. The queen size was about $900 Feb 2022 when she got it.
It also is 2 sided so you can flip the bed over. I am in California and was not able to test it. I really need to try out a mattress before buying. I tried buying online once and it was not as described.
