My 2 year old daughter is still in her cot bed but too big for a travel cot so this product is ideal for holidays and staying over at family and friends houses. I purchased the single bed set which comes in a soft plastic case (I bit tricky to get back in the same way of course!). The inflatable bumpers don't go the full length of the bed but I didn't have any problems with my daughter who is a fidgity sleeper. Be aware that the bumpers are not deep enough to stop a child climbing out of the bed if that is what you are aiming for.
I did have a problem with one of the bumpers having a slow pucture but was very impressed with the Amazon return service. I emailed the customer service department about 6pm explaining the problem and had a new set delivered the next morning, with a request to return the faulty item within 30 days after which you are charged for the extra item (fair enough I think)
Have recommended this product to friends and will be taking away for our 2 week holiday. Dusky Moon Dream Tubes Bumpers Single Bed Set
