Mattress Quality - Purity (Oak)
I purchased the Purity Mattress (Oak) in Firm and have had nothing but issues with this bed. The core spring was too small when delivered and the motion transfer issue is severe. It is by far the worst I've ever experienced on a mattress. If a pin drops, the entire mattress shakes like jello. I wake up multiple times every night when my partner shifts positions. BEWARE if you share a bed; unless you are a very deep sleeper, you will be woken up. As a side note, it is also strange that the website does not allow me to submit a review for the specific mattress (even though there is a place to do so).
