We purchased a Tuft & Needle from
Amazon during a Prime Day. Great price, cheaper than Casper, 100-day trial and return policy. We ended up returning it after less than a month. The mattress was mushy and had no edge support. The return was fairly easy. Contacted Amazon, which had special handling come and haul away the mattress. They literally dragged the mattress from my home and onto a truck parked across the street. I guess it went to donations.
While we still had the T&N, we went over to the Casper showroom in Cow Hollow. If you’re ever in the city, you should give it a try. Slept on a few of their models, and really liked the Original. I felt the Casper Element was too soft and the Casper Wave was too firm. There’s a new Nova model, too. The Original has a great balance of softness and support. I had recurring back problems sleeping on our old box spring, and the T&N just made it worse. I rarely feel back pain from sleep since getting the Casper Original. Their pillows have also been amazing for my neck.
Casper is much pricier, but they offer lots of opportunity to stack discounts. There’s a Memorial Day sale going on right now until 5/31 for 15% off their mattresses. (Although 15% off is fairly common.) However, if you purchase a mattress through a Casper supportal link, you can do better with 20% off. Also, check your Chase credit cards. Chase Offers also has an offer for 15% off Casper .com purchases over $350, with a maximum of $135 (YMMV - max spend $900). Don’t forget to go through/activate a shopping portal of your choice:
https://www.cashbackmonitor.com/cashback-store/casper/ Rakuten looks good at 2.5% (MR), or Chase Freedom UR portal at 3x if you’re willing to risk it not tracking. Casper also has a 100-day trial/return period on their mattresses, so there’s no risk and just a little inconvenience if you decide to buy it just to try it.
Ultimately, the mattress you sleep on is immensely personal. You’re not going to get the right answer for you from any one of us on the Internet. Don’t feel bad about trying a mattress (or several) and returning it if it’s not the right feel for you. That’s what their trial and return policies are there for. Good luck!
