My sister found these adorable inflatable sleeping bags (slumber bags) for kids made by Battat - and we just love them. They are really cute, durable and easy to use. I like that the bedding and pillow are already included and you just "zip" the kids right in. They are called slumber bags and they are really plush and soft. I found some online at Target. Here's a link to the sports themed version, or the Noah's Ark version, or the Flower & Butterfly version. There are a few more as well. Racetrack I think and maybe a princess version.
They've been a huge hit with the kids. We take them to hotels or anytime we travel. They roll up easily and are easy to wash because the outside zips right off. You'll notice the difference in quality right away. They are also great to have on hand for houseguests with kids.
They do come with a foot pump, but also blow up in about 10 seconds using a cool hairdryer, a reverse vacuum cleaner or even in a pinch you can even blow them up.
Make sure it is made by Battat. I've seen some really poorly made ones out there too. Those are generally called "Ready Beds". Avoid those. Go for the Slumber Bags by Battat if you can find them. At Target online they 39.99. I've not seen them in the stores though.
