took a chance and bought mine (twin size, I'm single and my house has an odd layout lol) for $130 from walmart a couple years ago. it's a huge memory foam slab with a cover over it and it's the most comfortable and supportive mattress I've ever had, especially for that cheap. I'll find the link and add it below!

pretty sure it was this one, and it's on an even better sale right now than it was when I bought it! [link](https://www.walmart.com/ip/2247654167?sid=0564fa67-48bd-4879-81e3-d61757e1a9e4)

I got a cheap 8" zinus memory foam mattress ($200 )about 6 years ago for the guest room. People still love it. I also got a more expensive ($1200) sleepez latex hybrid mattress that is pretty awesome as well. It's quality materials. I recommend the latex hybrid or a get a cheap zinus or novella or lucid from Amazon. The more you spend or dwell on the decision, you'll find more faults with it.

Sinus brand through Walmart is pretty good, it’s what my husband and I use and we really like it. It was nowhere near $1500. We have the 8 inch memory foam queen size and we paid less than $300 for it and have used it for over 5 years. We got a full size for a guest bed we had awhile back and everyone loves it so it was a good move.

Try the zinus memory foam mattress from Amazon. I bought it like 5 years ago and it still has the same firmness and is even across.

I just bought a Zinus memory foam after reading multiple positive reviews and I love it.

Most mattresses are pretty much the same materials with different marketing. The “cooling” tech stuff is all just BS. Focus on the warranty and return policy more than anything. My Zinus memory foam mattress was like $400 on Amazon and going strong after 2 years. Not the fanciest, but definitely good enough!

I really like my Zinus memory foam mattress and it was right around $300
