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.

    Mismatching measurements

    Posted by Ben on 29th Dec 2022

    1) Well I got an invitatation to review before the even responded to any of my emails. 2) There are a few conflicting measurements for the bunk board. 3) I spent 51.5p on decorative hardware that are too small/narrow for the pilot holes the instructions indicate and will be dangerous to install as they will slip right out of the pilot holes.

    Loft or Bunk bed plan ex long twin

    Posted by Mary Keeler on 28th Apr 2021

    Great plans - read carefully and several times- they work like a charm. Excellent customer service - USPS shipping was challenging - hopefully they will connect with a different shipper. Sturdy and attractive loft - We actually put a standard twin bed - mattress and box spring on a metal bedframe with casters so it slides out for easy of making the bed! One coat of waterbased black stain from Saman then water based polyurethane gave a great finish and no odor!! Their hardware looks nice.

    Very clear instructions with a few slight omissions

    Posted by Alan Pepe 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.

    Great value on hardware kit

    Posted by Diane 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!

    Posted by Jessica from Riverdale, Utah on 7th Dec 2011

    My husband just finished building the Loft/Bunk bed for our two boys (ages 7 & 4) and I am amazed at how simple it was to build and how sturdy it is. I know it will hold up for years to come. Thank you for such a great quality bed for an unbeatable price.
