There are small holes near two of the tufted areas on the matress that look like the tufted holes.  I'll never be able to get the matress back in the box and there was a risk of the next one being the same.   I  like the matress so I decided to get a cover for it.  I had also ordered a futon frame to use the matress on but have yet to receive it.  I've had the matress over a week so I hope to get the frame soon :-/
