Very small. Had to return as it does not fit the frames we ordered

They are smaller than the typical twin size, there’s a big gap in the twin frame. So disappointed.

Wasnt listed as narrow twin, nor had narrow measurements listed. Just listed as twin. Now its way too small for my grandsons new bed. Please do better and list exactly what youre selling so customers are fully aware of what they purchase!

Amazing! Just what I wanted. Not very high and very comfortable. Kids loved it

It was a little smaller and not as thick as I expected however it came promptly and was packaged well. I love Wayfair and have never been disappointed

The master takes a few hours to fully come together, but is very nice and comfortable 

Original description did not list it as narrow twin. Does not fit the bed. This is a mattress for a navy rack.

Perfect size, quality is good. It's not to thin. Perfect for my son.

Pretty good

Bought this mattress for my daughters bunk bed it fit pretty good, it’s also pretty comfortable for the price. The sides took a little while to puff up but they did eventually. Not a bad buy for the price.
