Trundle by Coaster
For the ultimate in efficient use of space, we have the Low Profile Trundle with just a 3.75" height. Place your Twin mattress (not included) on top and roll it under any bed with enough clearance (clearance must be greater than 3.75" plus the height of your mattress). When bedtime comes, simply role it out from under the bed and you are ready with a place for your guest to sleep.
