This is an ABSOLUTE piece of JUNK. The boards are consistently cut 1.75 cm too long to fit our standard twin for our toddler. This results in constant displacement of the boards and a safety hazard for our daughter. I tried to contact Wayfair support and it has been challenging to connect with anything other than a chat bot. Our other option is to cut these ourselves with a saw, however this is VERY suboptimal. 100% DO NOT RECOMMEND this product. This is consistent with the other 1 star reviews. VERY poor quality control.
