I think we're going to need a ladder

Last year we bought a new bed from IKEA. The bed frame is great, but the mattress died after one year. (It was cheap, you get what you pay for.)

But now we have the "bowling ball" mattress. (You drop a bowling ball on one side and a glass of water won't spill on the other side.) But, is it high! We need a ladder to get in. (Or a springboard.)
