There are some budget models I’d avoid. Many of these beds are extremely affordable, and if you aren’t picky, they may feel fine. Just don’t say I didn’t warn you. The $237 AmazonBasics and $259 Zinus mattresses were made of cheap foam that wasn’t dense enough, causing too much sinkage. (I had to return a Zinus of my own for this reason.) The $250 Linenspa mattress is also certainly affordable, but it has coils that aren’t individually wrapped and felt uncomfortable, with an uneven, mushy feel to it. It also didn’t fully inflate near the edges, so they drooped. Some Amazon buyers have also complained about this. Finally, the $1,899 Parachute Mattress didn’t have enough proper padding above its coils, given the extravagant price.
