Easy to shift or break coils on an innerspring?

offset or bonnel coils, king size with pillow top… if you keep the mattress standing on it’s side for a day or two, does this hurt the coils?
how about if you lean the mattress against the edge of a wooden bed frame and the mattress sort of bends at this sharp wooden edge… does that hurt the inner coils?
used to foam beds that you can bend, etc… so not sure if other precautions need to be taken with innerspring mattresses? and whether offset/bonnel coils versus pocket coils have different handling guidelines?

Hi needanewmattress,

If the mattress is stored in an upright position and doesn’t bend sideways then it would generally be fine for a few days although it can cause any layers that aren’t glued or tufted or aren’t attached to the coils to shift or bunch together. If the mattress has a zip cover then you can unzip the cover to rearrange any internal layers that have shifted. If it doesn’t then it can be much more difficult to successfully realign the layers inside that have shifted by trying to hold and lift the layers that have shifted while you are moving them back to the position they should be in through the cover and quilting.

It could hurt the coils yes if the mattress has a border wire which isn’t designed to bend at sharp angles. If the border wire is damaged or permanently bent it would also void the warranty. A general rule of thumb is to avoid bending a innerspring mattress that uses coils that are attached together with helical wires and/or has a border rod more than about 10 - 15 degrees unless it is specifically made or hinged to bend at specific hinged articulation points for moving or for use on an adjustable bed (and then only bend it at the hinge points which can sometimes be width or sometimes length). Pocket coil mattresses that don’t have rigid border wires are more flexible and can bed more than this (enough in most cases to be suitable for use on an adjustable bed for example) but some of them have foam surrounds which can be damaged with bending past a certain point and I would still avoid any extreme bending such as doubling it over or sharp bends more than about 45 degrees with these as well.

As you know Foam mattresses are usually more flexible and are fine with bending although again I would still reduce the time they are bent to the minimum possible.
