Spa Sensations 12" Theratouch Memory Foam Mattress

Been buying Walmart mattresses for ~$300 and never going back. Also to clarify the plural: started with one and now have 3 on 3 beds. Original is 6 years old and still solid, just moved it! Spa Sensations by Zinus 12" Theratouch memory foam mattress, King was $289 at the end of 2019

Zinus Spa Sensations 13" memory foam mattress at Walmart. Was about $350 when we got it years ago, probably has gone up in price but would still be under your budget

I got a Spa Sensations memory foam + gel mattress about 10 years ago, and I really liked it. I think it's time for a replacement now because it's developing a bit of a divot, and I'm dreading the expenditure. I'm 6'5" and about 315 with a bad lower back.

I bought a Zinus for my guest room years ago and it’s great! Even my elderly parents like it when they visit. Get the 12inch one, it’s worth the small up charge over the thinner models.

I have a 7 year old Zinus 12 inch and it's still great. I just got 8 inch, I think, for my kids beds. Theirs are super comfy as well but it's only been a couple of months so I'm unsure about longevity.

Bro I bought a Zinus foam mattress almost 9 years ago and it's the best mattress I ever bought for $200 shipped.
