For the past several months it has become apparent that #3 needs a new bed. He has been rapidly outgrowing his, and we had planned on getting him something for either his birthday in November or for Christmas.
I've been ferreting away a few bucks each month for a while now with that goal in mind. Then I heard the ad on the radio. A local mattress store is having a sale ($99 for each piece of a mattress, so $198 for an entire bed).
Realizing that this was too good to pass up, Hubby and I got #3 his new mattress today.
He is upstairs now putting it together and re-arranging his room to fit the bigger bed. It's only a full, but at least he won't be hanging off any of the edges for at least a few years!
