The idea is a good one, but the execution could use some improvement. The fitted sheet is not quite deep enough, so my son complained that he needed another blanket to be warm enough during the winter months, but then it was too hot with just the "comforter" during the summer months. The zippers wouldn't stay closed during the night.
Thankfully, I am a seamstress, so I have taken their idea and modified it. I had to purchase elastic clip-on straps at a local store to keep the fitted sheet on the bed. I purchased zippers online that have a "locking" slider and replaced the pulls on the set. I made a cover that is just a sheet, for hot weather. I made a second cover that is a much thicker comforter, for cold weather. Amazingly, the cost of the materials for these adjustments was less than the original Zipit set. With these modifications, my son loves his "Mama's Zipit" bedding.
Bottom Line: Yes, I would recommend this to a friend
I just want to acknowledge you for being a great mother!
