July 26, 2025 -
I put off getting a new mattress for fourteen years because they’re so expensive in stores. I finally bought one on Amazon after my mom had ordered on Walmart’s website.
I was very apprehensive because we couldn’t try it but I read hundreds of reviews.
It was super cheap. Less than $200 for a queen. This was five years ago.
It’s the best mattress I’ve ever had.
Getting it in the mail is much better than getting it delivered by the store.
ETA: It was ZINUS 10 Inch Support Plus Pocket Spring Hybrid Mattress
