Customer Reviews
So happy with my mattress!
I bought the King Size Mach II mattress, and it's been amazing. Setup was pretty easy, just took 15 mins. The customizable firmness is genius! My partner loves the firm side, and I went for plush. Sleeping so much better now. Will definitely buy from them again for our guest room!
Good mattress, decent deal
I was looking for a new mattress, and the Mach II caught my eye. I got the queen size during their seasonal sale, which saved me a bit, around $200 off the regular price. It shipped pretty fast, took about 6 days to get to my place in California. The mattress itself is pretty good, comfortable enough, and the ability to choose between firm and medium is nice. I still think it's a bit pricey even with the discount, but so far I feel like it was worth it for the quality. I'd consider buying from them again if there's another good sale.

Hey everyone, thinking about getting a Sleeping Duck mattress but also eyeing a Koala mattress. Anyone have either and can tell me how they stack up, especially for side sleepers?
