Great mattress for my college dorm and easy transport.

Excellent mattress

We just recently got this mattress for my son as we were moving him out of a twin mattress.  The mattress inflated nicely and fits great on our new bed frame without a foundation or box spring underneath.  He has slept great on the mattress since the first night.  It is very supportive and comfortable.  He loves it!

Great and comfortable mattress!

It was time for my children to get new mattresses and I decided to purchase this brand. Let's just say they loved them, and they have been staying in their own beds now. Just like Goldilocks and the Three Bears, they are not too hot (firm), they are not too cold (soft), but they are JUST RIGHT!

I bought a set of twin mattresses and they are so perfect for what I needed. This is for a guestroom trundle bed. I ordered the 8 inch so it would fit conveniently. After placing it on the beds, within two days, they fully expanded to the 8 inches. They are firm yet comfortable at the same time. I needed them for a second floor bedroom so having them in a box was so much better than carrying mattresses up the stairs. I would definitely recommend these.

Great mattress in a box!

This mattress is fantastic! It's so hard to find mattresses that are not taller than I am when placed on a bedframe that still feel comfortable. I had a hip replacement a few years ago and it can sometimes be difficult to sleep as I was a long-time side sleeper trying to sleep on my back. However, since getting this mattress I have had no issues sleeping on my back. It's a truly wonderful addition to my bedroom, deserving of all 5 stars!

Perfect if you need a comfortable shorter mattress
