We ordered the navy because it was lower in price for our son’s big boy room. The pieces are incredibly sturdy. The unit we ordered comes with a trundle which of course requires two mattresses. The trundle bed shouldn’t have a mattress thicker than 8 inches. We went with a thicker mattress on the bed itself. We also added a toddler rail for safety (Regalo). Overall great buy. Would recommend setting it up in place to avoid the pitch roof scratching your ceiling
