  • Good price for great bed
Style: 10 Inch Size: Full
Il this is an extra bed I bought for guests. I had my daughter already sleeping in it and she said it was so comfortable. I did not sleep on it, but I did lay on it and it felt great.

  • Amazing & comfortable as hell
Extremely comfortable. Great quality & looks amazing. Super light weight. Weird to say but very cool opening it. I love how getting on it doesn’t disturb my wife or newborn. Great purchase. I do want to say if you buy this & are looking for a box spring, DO NOT buy the 2 piece twin xl they tell you to buy. Buy the one piece California king box spring. ... show more
