Review: Surprisingly great quality! - We have two of these now, in both full size and queen. I had some concerns about the "mattress in a box" shipping method. After allowing time for the mattress to expand, you'd never know it was shipped like that. Very comfortable hybrid design, stays cool. Would buy again! The price is fantastic.

Very surprised that a mattress in a bag would unroll so quickly. Seems great so far. Using in a spare room so won’t get everyday wear.
