Product Description

Loft bed plan tall height for an extra long twin mattress

Many of our teens and college students need an extra long twin mattress - here is the plan for that tall person!  The ultimate room expander - you can sleep and study in the space your bed takes in the room.  It works well in a room with standard 8-foot ceilings with enough room for an adult to sit under the bed and work at a desk!

Loft Bed Plans showing how to build a Loft Bed or Bunk Bed that is extra-long and extra-tall. This loft or bunk bed measures 75 inches tall, by 42" wide, by 88" long with 58 inches clearance below. This Tall Loft Bed can easily accommodate an adult seated at a desk below and adult weight on the bed. Contains Additional instructions to convert to an Extra Long Tall Bunk Bed. It works well in a room with 8 foot ceilings. It uses widely available easy to obtain materials and a XL single (twin) size mattress. Extra long mattresses are easy to obtain and are commonly used in dormitories and institutions as well as many homes. You can build this bed from our plan even if you have little or no woodworking experience using a circular saw, an electric drill, a power sander and a few hand tools. By purchasing our bunk bed plans or loft bed plans you can build your own Loft Bed or Loft Beds saving hundreds of dollars and still have a good quality solid sturdy bed like those built by Bunk Beds Unlimited. The hardware kit includes all bolts, screws needed to complete the loft or bunk bed. Additional hardware such as wooden drawer handles and heavy-duty carpet casters for the trundle bed is available by ordering the bed and drawers hardware kit. (Please note that lumber is not included.) Our hardware kits are higher quality, much more convenient and usually a better price than if you purchase the items at your local home center.

  1. Very clear instructions with a few slight omissions 4 Star Review

    Posted by on 16th Sep 2020

    The plans were really well designed. There are some places where there are some details lacking.
    It would be useful to have information on the diameter of the holes. Also, more info is needed on the placement of the holes in the upright to hold the ladder rungs. I was tripped by this but it still worked out OK.

    Well done! Total time to build it out of dimensional spruce lumber: approx 35 hours over two weeks. It was worth it.

  4. Great value on hardware kit 5 Star Review

    Posted by on 13th Dec 2011

    We bought your plans and decided to shop prices at our local hardware store - then we came home and imediately ordered your hardware kit! Your kit is a great value compared to the local home improvement store - then we were even surprised again when the hardware kit arrived two days later to find the hardware is MUCH higher quality than what we had priced locally. THANK YOU for such great plans and hardware kits!
