  • Doesn't seem to be full 6 inches

    The mattress took about three days to fully expand, and it feels good to lie on. Sitting on the edge of it makes it compress a bit, but it hasn't warped it. It didn't expand to fit the cover snugly, and I was not able to make it fit properly, so I worry that with use it'll shift and be unattractive. That is my main reason for a rating of four.

    • How did the color on site compare with the actual product? Good representation, but seemed more beige in picture
    • Please tell us about the quality of the product. Sleeps well, good support
    • How accurate was the on site description of the product? Very accurate
  • It's not a 6 inch mattress

    Mattress never "fluffed" up to be a six inch mattress. It's more like a four inch mattress. Other than that, I would say it's an okay purchase. It is comfortable, but I would have much preferred thicker so my sheets would fit better.

    • How did the color on site compare with the actual product? good
    • Please tell us about the quality of the product. okay
    • How accurate was the on site description of the product? not very good
  • worked well fro trundle bed

    It was nice, right firmness. It felt "solid" in construction. We used this for a top of a trundle bed and used the regular size one for the bottom.

  • For Children Only(no huskies)

    MY nephews say this is comfy they weigh below 90lbs. I had the misfortune of having to sleep on it one night I'm 5'7 135lbs and my butt was sinking to the box spring. Very uncomfortable. Probablly great for lite kids. Adults need to get something with more depth.

  • Great value at a Steal of a Price!

    We own a tempur-pedic mattress but did not want to invest in an expensive mattress for our daybed. We found the quality of the mattress amazing and the price unbeatable. I hope that guests will no find it so comfortable that they won't leave! Just kidding.

  • Problem solved

    Amazing! Thought we would never actually see a real mattress. Amazon fixed the error (we received dog mattresses by mistake instead of XL twin mattresses) and our kids now have decent mattresses! They come in small boxes which initially makes you dubious about the quality . . . The minute you pull off the plastic and air hits the mattress, the thin mattress expands! It's quite fun to watch! These mattresses have coils too! Whodathunk that they can vacuum pack coil mattresses like that? Anyway, well worth the wait! Thanks a bunch!

  • Expanded to listed size!

    I wanted to add to my earlier review that this mattress expanded to full size by the end of week 1. I found it a great mix of soft and firm, very comfortable!
