Overview

An 8 inch memory foam mattress in full size, shipped compressed in a box and finished with a bamboo charcoal infused foam layer. Foams are CertiPUR-US certified and the cover uses OEKO-TEX Standard 100 textiles. Rated medium firm.

The brand name includes the word Queen, but this specific listing is full size, and the seller's own product text flags that distinction directly, so it is worth double checking the size before ordering. Like most bed-in-a-box mattresses, it needs up to 72 hours to fully expand after unboxing, longer in a cold room. At 8 inches thick, it sits on the slimmer end for memory foam mattresses, which generally means less deep-compression support than a 10 to 12 inch model.

  • Full size, 8 inch profile
  • CertiPUR-US certified memory foam
  • Bamboo charcoal infused layer
  • Medium firm feel

Who it's for

Fits a full size bed frame or box spring and buyers who want a budget bed-in-a-box option with a medium firm feel. Not for anyone who assumed the brand name meant queen size, or who wants a thicker, more plush foam stack.

Pros and cons

Pros
  • CertiPUR-US certified foam and OEKO-TEX certified textiles
  • Bamboo charcoal foam layer
  • Compressed shipping makes it easy to move into a room
Cons
  • Full size only despite the Queen brand name, easy to order the wrong size
  • 8 inch profile is thinner than most memory foam mattresses
  • Takes up to 72 hours to fully expand, longer in cold rooms

Performance notes

Memory foam mattresses shipped compressed rely on the foam's own recovery to regain full loft, which is why the listing specifies up to 72 hours and warns that colder rooms slow the process. At 8 inches total, there is less foam depth than thicker models to absorb weight before you feel the firmer base layer underneath, which lines up with the medium firm rating given.
