I have been searching for a tent bed for a while... this bed caught my attention for both good price and good reviews! It is easily assembled and so far has been durable. My son, of course, LOVES it! I'm a little worried that in the future the part that wraps around the mattress may give out (as it looks slightly flimsy and keeps popping off the sides of the mattress) but I'm hoping for the best! If it happens I'll just cut the bottom bit off and use it as a regular tent, right?!
