Product Description

Classic Brands 4-Inch Low Profile Instant Foundation-Box Spring Replacement is a low-cost solution that provides the perfect support for today's higher profile mattresses. It's strong and sturdy structure prevents mattress sagging and supports newer heavier mattresses. The drawstring cover is easily removable and coordinates well with most mattresses. The compact foundation ships in manageable pieces for easy assembly and comes with a three-year worry-free warranty. Available in Twin, Full, Queen, King, Twin XL, Full XL and California King sizes.

Is it a Foundation or a Box-Spring?
This is a common question-they are essentially the same thing. They serve the same purpose as a traditional box-spring. The Classic Brands Low-Profile 4-Inch Instant Foundation supports all mattress types and as the name applies, it is easily and quickly assembled. The solid spruce foundation is made is the USA in Pennsylvania Amish Country and ships with all tools for assembly and a cotton blend cover.

Benefits of the Low-Profile Foundation
The Instant Foundation is made in the USA in the Pennsylvania Amish country. Made of solid spruce, the Low-Profile Foundation is a good option for people who have high bed frames or are purchasing an extra-thick, higher profile mattress. The 4-Inch Low-Profile Foundation is 4-inches shorter than a standard foundation, offering easier access to those who may have difficulty getting onto a higher bed. This foundation ships small parcel conveniently right to your door. Narrow hallways and small staircases won't be an issue.

Easy Assembly
The Instant Foundation is easy to assemble and sets up in minutes, just unpack, assemble the frame and attach the hardware. Next simply place the wood slats on the foundation. The cover fits right on giving you the perfect mattress foundation. All standard bed sizes are available, and the foundation works great with memory foam mattresses or latex mattresses. The difference in height between a low profile and regular profile foundation will change the amount of headboard that is visible. Made in the USA in Amish Country Pennsylvania of solid spruce.
•Step 1-Unpack box and lay out all materials •Step 2-Lay out the outer perimeter of the foundation, then find the middle support slats •Step 3-Using the provided hardware, screw the sides of the foundation together-(Detailed instructions for this step included with foundation) •Step 4-Lay slats in place on top of frame •Step 5-Screw in slats •Step 6-Cover frame of foundation and use drawstring to secure

Get it Right the First Time
It is also a good idea to check the size and the height of your mattress on to make sure you are ordering the correct size. Keep in mind that you should combine the height of the frame, foundation, and mattress to get a gauge of the how tall your bed will be.

Classic Brands Smart Packaging
Smart packaging reduces the carbon footprint in the manufacturers shipping process. Our advanced packaging technology means we can ship efficiently. The compact package delivers right to your doorstep and fits easily thought tight hallways or narrow stairwells.

Quality Assurance

Works, with some extra attention to detail.
This is a reasonably priced and sturdy foundation and it would have gotten five stars even with it's minor flaws had the manufacturer chosen a better case. I bought two of these in Twin XL (split Eastern King), and the covers didn't match. I was almost relieved they didn't match and I had to get different covers, as they stank to high heaven (an almost roofing-tar like smell).If you're only doing one bed (and not a split), then for the price nothing can touch this frame, even if you have to get creative with a case for it (although the stock case would probably be fine if you washed it several times).I spent four hours putting two of these together. This time included a trip to the local hardware store for wood and time spent cutting eleven slats and eight 2.5 inch pieces of 2x4 to beef up the frame. If you aren't handy (or you need someone to cut extra slats for you), then double that time.All in all, I'm happy with the results I obtained. I'm using two Twin XL frames as a split king foundation for a 12 inch thick 100 percent natural latex mattress. This mattress is very heavy (375 pounds without pillows or bedding), and there are no signs of weakness whatsoever. I didn't try jumping on the bed, but there is no movement at all with two grown adults on it. As long as it isn't a point source load, you could put a thousand pounds on these after beefing them up and not feel a thing.Things I recommend you do:1. Just go ahead and add extra slats as your platform will be stronger, and the spacing isn't adequate from the factory for most memory foam and all latex mattresses. Do NOT use plywood as some have suggested as a solid foundation is a moisture and mold risk except for on a waterbed. Read up on beds in campers and boats to see what kind of trouble you can run into when you put a foam, latex, or innerspring mattress on a solid foundation without any ventilation.For any size twin XL or bigger, you'll need 11 1x3 pieces of wood - you'll want them cut to length to fit the size you want. I used a chop saw to make 35 inch sections for a split King (two twin XL foundations).2. When you install the slats, apply a 2 inch bead of wood glue before you screw them down to prevent any possible creaking. This is permanent so only do this if you're sure you can get the assembled frame back out of the room later. If you cannot get it out later, rub on some paraffin or beeswax to prevent wood to wood squeaking instead. Be sure to put a little on the threads of the screws too.3. Use some blue thread locker on the carriage bolts. Loctite makes a product that fits this description (and would be the brand name product).4. Add some extra bracing between the top and bottom 1 inch thick prices of wood along the side and center supports (if you have center supports). A quarter of a 2x4 cut to small pieces of the right height (2.5 inches or so for the 4 inch tall versions) and some wood glue will work great. Put these bracing pieces under where your new slats will go for extra strength.
