The slats were too wide so I had to cut 2 inches off but in all fairness, it is a very old bed with an unusual support system. The slats, singly seem a bit flimsy and easy to bend so I am in hopes that they will support my 125 lbs, plus 20 lbs of dog for a while.
 On the plus side, Wayfair is a great company to deal with for customer service support and speed of delivery. They keep you informed of deliveries via text which is great so you know exactly when to expect deliveries.
