Comfy bed!

The product was fluffy! Waited three days so the funky scent of new product could fade away. When delivered the box was a bit ruin but the bed was not damaged because it was perfectly sealed. Came with its own cutter, make sure to read the instructions before opening and everything will work out fine!

Very good for the price

This is very comfortable. The mattress is soft and cushy. I would be careful about sitting on the edge of the bed; it's that soft. But the springs are good for support. I think this is a mattress that should be used on a frame that has a headboard.
