If your 6'4" and 245 lbs like me and thinking it's plenty long well it is. But the width specs are not the sleep surface only. Subtract a few inches for the bars on the sides. I had to return and get the XL version. However the claim they aren't stable as bunk beds isn't true I don't think. I'm big and stacked mine and it holds me fine on the top bunk no problems at all. With the security straps in place I don't see how they aren't safe in my opinion. They seem extremely well made and solid but make sure you size right. I've been sleeping in mine a month straight. Get a memory foam pad on one and it's good as my real bed easy. Without the pad is easily still adequate and comfortable but better with the pad.

We are so satisfied with the disc-o-bed, They are very comfortable. We love it.

Assembly is not difficult, but I takes about 20 minutes.

Love this! It is very comfortable and you get sound sleep.

Very heavy but very sturdy

Just what I need for occasional grandkids visits.

We love these beds. Very sturdy and comfortable. Great purchase!

Great product. It’s my second one I’ve bought!

Great for small space. Use as bunk beds. They are surprisingly comfortable.

This Bunk Cot is made better than my car. It is heavy steel solid as a rock. I did return it because it did not fit in our tent.
