Hi mo9090x,
As you know I think highly of Tuft and Needle and they are certainly a good quality/value choice (especially with their new design … see posts #2 and #6 in this topic.
Congratulations on your new mattress 
This would be true with almost every mainstream mattress you can buy or any mattress that is made one sided (including the Tuft & Needle) because the bottom layers are firmer for support and aren’t designed to sleep on and the upper layers are softer for “comfort” (they don’t have layers that are designed to sleep on on both sides of the mattress).
