Product Details

Spec Sheets, Assembly Instructions, and Templates

  • Converter Rail Assembly Instructions.
  • Curious about the bolt-on brackets? Here's a template for the bolt-on brackets.
  • If your bed hooks-on instead, please see the Full to Queen Converter with 3 Legs. 
  • Converter Rail Specs - legs adjust from 6 to 10.25". The center support safely adjusts from 53" wide to 57.5 inches wide.
  • Adding a converter rail to your full size bed is a bit like adding an after-market part to your automobile. After all, you're adding a mattress set that is 6" wider than was meant to be used on the bed. A strong word of caution - If you expect this product to be as sturdy as your original wood rails, you should buy a new queen size bed. Converting a bed is not for you. Some beds work brilliantly, while others, not so much.

Learn How Converter Rails Work:

  1. First, and this is VERY IMPORTANT, converter rails are uniquely designed to enable you to use a queen mattress set on a full (standard, double, regular) size bed. Therefore, converter rails only work on full size beds. Converter rails do not work on queen size beds. If you have a queen size bed or need queen bed rails, order QUEEN BED RAILS. Please call us if you are confused. We are always happy to help!
  2. On a full size bed, converter rails accommodate the WIDTH OF QUEEN BEDDING: The rails use 4 durable "L" brackets to accommodate the extra width of a queen size mattress. Click for picture.
    L-brackets are bolted onto the bed side-rails, which allow for the extra width of queen size bedding.
  3. Converter rails are the LENGTH OF QUEEN BEDDING: The usable space on our converter rails measures 82" - 83" long to accommodate the length of queen size bedding.
  4. Converter rails come with an adjustable height center support leg.
    Adjustable height center support leg safely adjusts up to 10.25" tall to provide the necessary support for your queen size bedding.
    that provides the proper support for a queen size mattress. Threaded leg safely adjusts up to 10.25" tall. If your bed is taller than 10.25" tall, please order a threaded rod with coupler.

Will converter rails work for me?

Converter rails fit most FULL SIZE beds- even antique ones. The following steps will help you determine if converter rails will work on your bed. Start by taking a look at your full size headboard and footboard. . .

  • STEP 1: THIS IS VERY IMPORTANT. Converter rails only work on FULL SIZE BEDS. (Full size is sometimes called regular, standard, or double size.) Is your bed really a full size bed? If your bed measures approximately 53" to 55½" wide, then yes, your bed is a full size. Continue to STEP 2. If your bed is wider than 55½", your bed is not a standard full size bed. Do not order this item without calling us and/or reading every word on this page very carefully.
  • STEP 2:Before ordering the item on this page, check your head and footboard. Many beds are designed for both full and queen sizes. If your bed is designed for both sizes, you will find two slotted areas on each side of your headboard and two slotted areas on each side of your footboard. The full size slots will be about 53 - 54 inches apart (sometimes 55"- 55½" apart) and the queen size slots will be about 58 - 60 inches apart. If you have slots for queen size, DO NOT ORDER THIS ITEM! Instead, order QUEEN BED RAILS.
  • STEP 3: Take a look at your current bed side rails. Do they appear to hook-on
    Picture of a typical hook-style bed rail bracket. Please note the measurements are not exact and may vary slightly by manufacturer, but work for most beds in which the rails attach by hooking in to the head and footboard. If they hook-on, you can order the Full to Queen Converter with 3 Legs.
    or bolt-on.
    The above picture is an example of a typical bolt-on bed rail bracket. Not all bolt-on bed rails will look exactly like this, but all bolt-on bed rails will have some arrangement of holes in which to secure bolts.

    Do you have bolt-on brackets instead? Here's a template for the bolt-on brackets. These are the ONLY two types of converter rails that are produced. If your current rails attach using a different system, you will need to have a local machine shop or welder customize a solution for you. (Or drill new holes in your bed.) To learn more, see Four beds that converter rails easily won't convert.
  • STEP 4: MEASURE THE HEIGHT of your current bed rails:

    If this distance is greater than 10.25", you'll need to order the Threaded Rod with Coupler. This leg extender (optional) makes the center support leg longer (up to 14") so that it will reach the floor.

    The overall height of your bed should be considered, as well. With normal wood rails, your box spring sits several inches down inside the wood rail. Converter rails work differently than wood rails. The basic design is a set of angle iron bed rails turned upside down. Your box spring or foundation will rest on top of the rails, rather than down inside of them. Using a converter rail set, your box spring will rest approximately 1 inch below the top hook. Often, this makes your bed taller than before.
  • STEP 5:Do you need additional center support? Not usually. But if you have a dual queen box spring (2 box springs) you will need additional support. Please order two TFCS001 supports.
  • Please note: There are hooks on each end of both hook-on bed rails or bolt plates on each end of the bolt-on bed rails. This allows you to attach to both a headboard and a footboard. You must have both a full size headboard and a full size footboard to use a converter rail set.

Comments: I wanted a queen size bed in my guest room, but I had an antique double bed frame. This solves that problem and was also higher than my old side rails, so that I could remove the risers that I had needed to be able to store luggage under the bed. Great product!!!!!

Comments: All the reviviews sound great, but the problem Is the single support in the middle/ center of the bed is lousy. It slips and bends with minimal use, resulting in the mattress sagging in the middle, resulting in a very uncomfortable bead.! Hi Rich, Thanks for your feedback. We'd like to help. We can think of a few reasons why this might happen.  We want to make sure you have the product listed on this page, the 515 converter rail. For many years, we sold a low profile converter rail, t... More details

Comments: I came, I saw, I ordered and they delivered. How simple was that! Plus, I compared the prices and they were cheaper or around the same as some of their bigger name competitors. Overall, I would certainly recommend them for quality solutions and we will be back to have them solve more of our sleeping challenges. Barry - Fredericksburg Va
