Serves purpose and inexpensive

It advertises a six inch foam mattress but looks more like 4” but I measured and it's 5” (shown on video) not counting the 1/2” trim on top and bottom. I didn't expect such a thin mattress (should have gotten a visual with a ruler before ordering. Decided to put old twin mattress under it and use this as a topper. It will definitely serve its purpose regardless.

The item came on time and very timely when we moved to our new place. Nicely wrapped in a box and Inflated quickly after opening. My daughter loves it and requested to sleep on it tonight but the instruction says allow 48 hrs to completely achieve its mattress quality. So far , its quite firm for me vut support my back well. Let's see after 48 hrs and will provide a follow up review.
