Beautiful bed but the width is larger than any mattress we can find. The slats on the bed show on both sides making it unsafe for pets and children. Unless you can find a king sized mattress that is 78 “ in width or don’t care about slats showing or the safety of that don’t buy the bed. We bought the suggested mattress from Wayfair; the mattress tag stated it was 78 “ in width but in actuality it was only 75”. 
Now we are in a dilemma and still do not have a solution with Wayfair. We either return the mattress; although we can’t find one that is 78”, return all of our bedroom furniture (we bought the dressers too; or pay to have the bed retrofitted or a mattress extender made.

Still waiting for a final resolution from Wayfair after weeks of exchanging emails. When we call we have waited on hold for over an o we each time and have never been able to speak to a person!
