Before we thought about mattress extenders, we always used pillows with our patients. They were however not the best solution since they were not the best mattress gap filler. They would also squish easily since they were soft and fall down necessitating the patient to get out of bed and fetch it. Getting a pillow that would fit the 35″ width of the bed was also difficult. It is then that someone told me that we could do with mattress extenders and when we bought one, we never looked back.

mattress extender block

The mattress extender is a rectangular block of foam that is placed at the end of the head or foot board of a mattress to protect the patient from medical bed entrapment or for taller people who would not fit on the traditional mattress. The mattress extender fits seamless on the bed so that the patient will not feel any discomfort while sleeping. It also makes the mattress non-slip such that it does not move on the bed.

Graham-Field 4INEXT Foam Mattress Extender, 4″ x 35″ x 6″ block

Out of all amazon mattress extender blocks, we found the Graham-Field 4Inext foam mattress extension to be the best for all types of mattresses.

The 4″ block  fits seamless with your normal 80″ mattress on an 84″ bed protecting the patient from entrapment as well as for making the mattress hold firmly into place. It would also be great for those tall residents.

What we Loved about this mattress extender

♠Just like the foam mattress, the extender block comes with a easy to clean, non-allergenic cover and as such you need not worry that your patient will get infections or skin irritations from it.

♠The extender is latex free and did not have any odor. We were able to use it the very day that it arrived from Amazon.

♠Our overall objective was to get something that would stop any form of bed entrapment when the patient lies their head between the edge of the mattress and the head/foot board. We were able to nail this with the Graham extender.

♠Soft material. The tall patients said that they noted no difference since it was as comfortable as the mattress itself.

♠You need not worry about losing your pillows again since the extender fits the gap so that the pillow is yours to rest on and not to fill headboard and mattress gaps.


What we did not like about it

▼The foam material squishes easily with time. So not very durable especially for tall patients who sleep on it for the better part of the day.

Mattress Extender 6″x36″x6″

You can never go wrong with the mattress extender 6”x36”x6” that is manufactured by the reputable mattress company Crown Medical. This mattress extender comes while it is covered in a Chemsafe medical grade vinyl cover which is easy to wash and keep clean. The foam and the covers are anti-microbial and are as per the California laws on fire-retardency and as such you need not worry about the safety of your patient.

►Measures 6″x36″x6″

►Covered with Chemsafe medical vinyl



What We Liked about it

♠The mattress extender 6”x36”x6” was hard and would not squish easily. It promised of a long-lasting life. The foam was high compression polyurethane.

♠Crown Medical promises of getting you just the right fit of extender depending on your need. So you can always measure your hospital bed and send in the sizes so that they can check whether they have what you want.

♠The bottom of the extender block is non-skid and as such you need not worry of it skidding away under the patient.

♠With the right match of the extender, one needs not know that you have elongated your mattress since when I placed a bed sheet on the mattress, it appeared uniform all through from the mattress to the extender.

♠Other than being easy to wash, the vinyl top cover was durable and would stay for long before I had to buy another one.

♠Other than accommodating my tall patient to fit on the bed, the extender was also good in protecting them from entrapment as well as keeping accessories such as books, pens and phones on the bed without falling between the wide space between the bed and the headboard.

Guide on choosing your Wedge and Matress Extender

So what are the pointers to look out for as you choose your best mattress extender and wedge.


High density extenders and wedges are going to last for long giving you value for your money. At the same time,they will not squish easily so the bed occupant is able to lie their head on a level or even raised ground. It would be senseless to have a high density mattress but an extender that squishes or sinks anytime you lie your head on it. It would be uncomfortable, right?


A good extender or wedge should be easy to clean. I like the vinyl covered ones since all you have to do is remove the vinyl cover, wipe it clean and then replace it. The cotton ones on the other hand though soft are not really good since you will have to clean every day off the sweat and drool. It will also take sometime for the cotton material to dry.


Get a durable one that is going to last for long. Extenders and wedges are not things that you want to buy after every one month, are they?


The item you buy should be working to prevent bed entrapment. If it always falls through the gap, then you got scammed and should return it.


I like wedges because other than use it to prevent entrapment, you are also able to use them as pillows

Odorless, non-allergenic and fire retardant

You do not want anything that smells of latex or is allergenic, do you? At the same time, the material needs be fire retardant so that in case of a fire outbreak, it does not catch fire easily.
