This could be really dumb question, but I just want to make sure a 2 inch bunkie board on a regular frame would be adequate for my new double-sided, individually pocketed innerspring mattress. I just got the mattress and boxspring set and frame. I was only able to see the single sided model in the store, and it didn't occur to me that ordering the mattress with two sides would add so much thickness to the mattress that it would make the total bed height ridiculous (around 31.5").

My options are to swap out the 9" boxspring for a 5" boxspring, but I'd like to go lower if possible- my only other option is a 2" bunkie board on the frame according to the salesperson. I'd like to do this, but just want reassurance that a bunkie board will not hurt a double sided innerspring mattress, decrease it's lifespan, etc... had read some stuff about those types of mattresses needing a boxspring for the flexibility....so I don't know what to believe.

If you can offer me some insight, I would greatly appreciate it!! Thanks!

Hi LongsPeak2015,

This could be really dumb question,


IMO opinion ... the only "dumb question" is one that isn't asked :)

My options are to swap out the 9" boxspring for a 5" boxspring, but I'd like to go lower if possible- my only other option is a 2" bunkie board on the frame according to the salesperson.

I'm not sure if you are clear about the difference between a box spring and a foundation (or a bunkie board). A box spring has springs inside it that flex under the mattress and because they are an "active" part of the design of a sleeping system (mattress and box spring) they can have a significant effect on the comfort, support, and the durability of some two sided mattresses (particularly if the mattress has "linked" springs). On the other hand ... there are very few one sided mattresses today that are designed to use a box spring as a support system and in many cases they will invalidate a mattress warranty for a one sided mattress which generally do best with a foundation that has minimal to no flex (vs a box spring that flexes) or a platform bed which also has little to no flex under the mattress. There are many in the industry that mix up the terminology between box springs and foundations even though they are very different products.

There are no specific guidelines that cover every possible mattress/support system combination in the industry so I would always check with the retailer or manufacturer that makes or sells it to make sure that a support system meets the warranty criteria for your mattress and follow their specific recommendations for the mattress that you purchased. If they confirm that a rigid foundation (or bunkie board) would be suitable for your mattress and would meet the warranty criteria then it would generally be fine but I would keep in mind that if you are currently using a box spring (vs a foundation) under your mattress that has springs inside it that flex and replace it with a foundation or a bunkie board that has little to no flex that it may change the feel and performance of the mattress and can affect whether the combination is a suitable "match" for you in terms of comfort, firmness, and PPP (Posture and alignment, Pressure relief, and your own Personal preferences).
