April 28, 2024Good quality king mattress?
I was told a while ago that you should test each mattress for 15 minutes. 5 minutes on each side and 5 minutes on your back. If you feel good getting up after those 15 minutes it's a buy. Been doing this everytime and picked out great mattresses I love. A good salesman will point you in the direction of the price you want to pay. More on reddit.com

February 3, 2022King size mattress recommendations?
Every time I find a brand/mattress that looks appealing and seems to have good reviews on the surface I do more in-depth research and seem to find majorly negative reviews and complaints, especially if the person has owned the mattress for a longer period of time. Listen, you will find a lot of negative reviews in the mattress world because 90% of people don't take the time to really understand what it is they need. If you like the sound of a mattress then try it, don't dig too much into the piles of negative reviews because every single mattress will have them and your experience will likely vary.

August 4, 2022Is a king mattress necessary?
It’s beyond necessary. But we’re not cuddlers at all. I would prefer even bigger TBH. Whenever we stay somewhere and it’s a queen, we’re both totally bummed out and can never sleep that good, even if it’s super comfortable. More on reddit.com
