  • No assembly needed
Size: Twin
Easy to prepare to put on a twin bed. Serves the purpose for which it is intended, foundation for a mattress. Feel confident when ordering

  • Bed
Size: Split King
Perfect for me in my new home!!!!

  • What an ingenious design!
Size: Full
When the box arrived to the door I couldn’t imagine that a boxspring could possibly fit. BUT Low-and-behold, I was wrong. It took two of us to initially wrestle the mattress open but once it opened it was “like magic” READY to go on the bed frame. I’m unsure how long that the mattress cover material will remain looking nice. It has that texture that makes me suspect it may not last. I hope that I am wrong “again”.. So far I am quite happy with this purchase. The price, front door delivery and my own capacity to carry it into the house by myself a double plus. ... show more

  • Easy set up ever!
Size: Full
Between the package and opening took under 10. That’s only because I opened it by myself and I’m small.

  • SUPER EASY!!! Highly recommend!! 🙌🏼 ⭐️⭐️⭐️⭐️
Size: Split Queen
This was purchased for my daughter who purchased her first house. Her bedroom has a very narrow staircase with a sharp turn. She told me it was effortless to set up! She said she took it out of the box and unfolded it, and that was it. She is extremely happy! And that makes mom happy too!!
