My husband and I absolutely love this bed! It took us 2 hours to build and after we finished we took a nice nap on it. We have a 10” king size medium mattress we got from Wayfair last year and it fit perfectly in this bedframe with no gap between the headboard! The lights are also amazing and can definitely set the mood in the room! We have been extremely happy with this purchase and would definitely continue to purchase more furniture through Wayfair for years to come.
