It is important the Ergoflex mattress is used on the correct sized bed base to perform optimally, as well as to prevent warranty-voiding damage arising over time. Unfortunately we cannot offer free returns in cases where an incorrect sized mattress has been ordered and unboxed, as this is not covered our home trial policy.
For these reasons we strongly recommend measuring your bed base prior to ordering. Please be sure to correctly measure the area where the mattress will be positioned, particularly in bed bases where the mattress will be within a frame. If you have ordered a bed base from a third-party that you have not yet received, please refer to the manufacturer’s specific recommendation on mattress specification. However, Ergoflex cannot be held responsible for any potential sizing errors arising from this.
