Does the mattress feel comfortable to the touch?

Sleeping on the mattress is not the same as touching a girl. Here are a few points to note: the stitching on the fabric should be even and tight, without any creases or loose threads. The edges of the mattress should have a smooth, uniform curve without any exposed frayed edges. When pressed firmly, the mattress should not produce any squeaking sounds internally, and it should feel comfortable to the touch.

Are there any刺激性 odors inside the jar?

Open the zipper and inspect the inner lining of the mattress. Sniff it to see if the smell is overpowering.

Lay back and feel if it fits your body comfortably.

Now, many retailers recommend that customers try out a mattress by lying on it for a ten-minute nap. If the mattress has good rebound and fits the body's curves well, that's a good sign. And if it's a double mattress, if one person moves around, the other should not feel the mattress摇晃. That's even better.
