You can chuckle a little, but no laughing.
The box springs that we tried fitting into the bed with the "too short rails" is actually a twin XL. Yeah, it never crossed our minds to check the tag to see if the box spring was the problem. Now we have a twin XL box spring and 2 twin size bed rails. Ugh!
I just have to laugh about it, so I guess you can too. ;-)
The furniture store is going to have a reg. twin size one for us on Friday.
All will be well soon!
