Hi everyone, it's my first post!

I need to elevate a bed by 4 inches for a while. I did some work on this problem already. Here's all the information I used to reach my conclusion:

expected total weight with mattress and occupants = 220.92200 kilograms
bed weight = 54 kg = 54,000 grams = 119.05 lb
bed dimmensions = 199.4 x 106.7 x 149.9 cm

cross section of the legs = 6.205 cm
radias of the legs = 3.10125 cm
area of the legs = 30.22 cm2
circumference of leg = 19.5 cm (Does not reflect the actual around of metal contacting floor)

My original plan was to get PVC and just put the PVC around the legs of the bed. I looked it up and PVC's compression strength and modulus are about =

Clear PVC pipe Physical properties
Compressive Strength psi @75°F 8,300
Compressive Modulus psi @ 75°F 307,000
http://plascowelding.com/pdf2007/PVC&CPVCPipeandFittings/PVC-Clear-Pipe&Fittings/PVC(SCH.40&SCH.80)ClearPipe.PDF

PSI to Pa conversion
8,300 PSI * 6,894.76 Pa/PSI = 57,226,508 Pa
307,000 PSI * 6,894.76 Pa/PSI = 2,116,691,320 Pa

I ran the numbers assuming that I could use the pressure the legs exert as a decent yardstick to approximate how much stress the PVC would have to endure:

220.9220 kg * 9.8 m/s^2 = 2 165.0356 Newtons

2 165.0356 Newtons / 8.96 centimeters^2 = 2,416,334.38 pascals

Now the 8.96 cm^2 figure is based on the thickness of the beds legs which are hollow.

2,416,33.38 Pa < 57,226,508 Pa & 2,116,691,320 Pa

But... I feel like I'm missing something with this. I want to verify my conclusion before going ahead with this.

If my stuff is completely bogus then by all means suggest an alternate method.

We used to prop the box spring up on milk crates.

Also you could just try it. If you have total structural failure you will be falling 4 inches. On a mattress.

Try to get tubing that rests flat on bottom of the main frame. Avoid having any lateral or point stress from braces, welds, bolts, etc.

Bricks or wood blocks work as well.

You have only considered the static loads, the dynamic loads may exceed those significantly. You need to consider young ones using the bed as a trampoline.

I think there are better ways to get where you want to go.
In addition, depending of the size of the PVC, movement on the bed might impart a moment
where the metal leg contacts the PVC and split it open.

1. Can PVC safely support the weight of a bed and a person?

It depends on the thickness and quality of the PVC pipes used. Thicker pipes with a larger diameter will be able to support more weight than thinner pipes. It is recommended to use schedule 40 PVC pipes which are specifically designed for structural use.

2. Will elevating my bed by 4 inches with PVC affect the stability of the bed?

As long as the PVC pipes are securely attached to the bed frame and evenly distributed, the stability of the bed should not be affected. It is important to use proper adhesive or brackets to secure the pipes to the bed frame.

3. Is it safe to sleep on a bed elevated by PVC pipes?

If the bed frame and PVC pipes are securely attached and the pipes are of good quality, it should be safe to sleep on the elevated bed. However, it is important to regularly check for any signs of wear or damage to the pipes and make necessary repairs to ensure safety.

4. How do I elevate my bed using PVC pipes?

You can elevate your bed by measuring and cutting the PVC pipes to the desired height, attaching them to the bed frame using adhesive or brackets, and evenly distributing the weight of the bed and the person on the pipes. It is also important to make sure the pipes are securely attached to the bed frame to prevent accidents.

5. What are the advantages of elevating a bed with PVC pipes?

Elevating a bed with PVC pipes can provide additional storage space under the bed, improve air circulation to prevent mold and mildew growth, and reduce acid reflux or snoring by elevating the head of the bed. It can also be a cost-effective and easy way to adjust the height of a bed without purchasing a new bed frame.
