3 LB Gel Custom Memory Foam Mattress Topper

Wanna Make Your RV, Truck, or Boat Mattress Really Comfortable?

You spend a third of your trip sleeping…Right?  Well at least you’re supposed to!  But let’s face it…you never get a full 8 hours of sleep do you? 

Why do motor-homes, semi’s, and boats have such a terrible mattresses?  The truth is, most manufacturers are trying to save money and they realize that potential buyers generally don’t factor in “mattress quality” into their buying decision.

Just because you’re on the road, doesn’t mean you have to sleep like you’re on the road!

If you’re looking for an affordable way to make your existing boat mattress more comfortable, then consider getting our 2″ 3 LB Gel Custom Memory Foam Mattress Topper!

I’m looking for a 72″x 80″ mattress topper for are 5th wheel camper. The mattress in this is so hard I need it softer. my question is the two of us are bigger people about 225 lbs & 289 do you think a 4″ thick would work or should we try a 6 ” ?
Aunt patty on Sep 18, 2017
BEST ANSWER: Hello Phil. Our mattress toppers are 2″ thick. We could customize something for you in any thickness you would like. Toppers are generally for cushion, not for support. Give us a call to discuss!
Do they make round toppers?
A shopper on May 10, 2019
BEST ANSWER: Hello! We can certainly help with that! Please give us a call to discuss!
I notice that this custom topper is rated a little more than plush. Does this make it too soft? I would want a little more support than plush
A shopper on Feb 11, 2018
BEST ANSWER: Thank you for your interest in Mattress Insider! The 3 LB Custom Memory Foam Mattress Topper is more on the soft side, it is rated 3 out of 10 in firmness. Another great option, if you would like more support, is our 2″ Brookside Memory Foam Topper which is rated at a 5 out of 10. If you have any other questions, please feel free to call or email us.
We are looking for a 72′ x 75″ mattress topper for our king sized short motor home bed. My only concern is that the memory foam topper might be warm for me and was hoping for a more ventilated type fabric. Do you work with other fabric types?
A shopper on Oct 23, 2016
BEST ANSWER: Hello & Thank Your for your Question!
We do have other fabric types available. To help reduce the body heat retained in memory foam, you may want to consider our Cool-Max zippered cover. Please give us a call to discuss your options.
Will this work for a mattress with a slide out? The current mattress is in two pieces
A shopper on Aug 4, 2018
BEST ANSWER: You are able to fold this topper over itself to allow the slide out to come in when not in use. Because raw memory foam has a tendency to easily tear when moving it, we would suggest you order it with the cover. Kind Regards!
Can this topper be folded up in a sofa sleeper or should it be taken off when closing the bed?
Christine R on Mar 22, 2018
BEST ANSWER: Hello! We recommend making up the 2 inches with a thick blanket or comforter to see if it will close.

Please give us a call if you need further assistance!

Thank you!
We have a 72×80 king mattress in our RV. My husband likes it because it is firm. It is killing me! My hips and shoulders hurt like crazy. We have tried cheap toppers and after less than a year, my 200 lb husband cannot get out of the dip. For his sake, we have returned to the mattress that came with the RV. He loves it! I hate it. We cannot afford one of your mattresses at this time but I had a thought. What if I purchased your two inch topper to fit on my side only. I would probably get a 30×80, but I would rather have a 34-36×80. What do you think of this idea? I can’t wait to do something. I know that the bed would be higher on one side, but not much. That I don’t care about. Please help me!
Lisa M on Sep 15, 2017
BEST ANSWER: Hi Lisa! We would be happy to help! Please give us a call to discuss your custom options!

Ordered two memory foam mattress pads for my RV - they arrived two days later and are outstanding quality. Better than a new bed at half the cost! Great company.
February 20, 2015
We bought a custom size mattress topper here (after much research on all brands) and could not be happier. The topper is super-comfortable and makes sleeping on the boat so much nicer. The customer service at this company and their honesty/integrity is also SUPER. We had a slight problem and they replaced the whole topper at their cost and with extra attention to be sure all was done just right. Don't buy elsewhere!

I bought your mattress topper for an RV bunk. You have saved my life! Before that I was constantly tossing and turning, unable to get a good night's sleep. Now I love camping again--it is so comfortable! Thank you thank you. We will be ordering one for the RV bed as well.
June 15, 2013
We have had our sailboard for 7 years. Each year the Admiral says how uncomfortable the mattress on the B-berth is. We have added egg crate foam and even an expensive spring type system. As a "this is our last try" effort we bought a memory foam topper from MI and the Admiral is ecstatic. Made a big difference. Fair price, good quality, prompt delivery. What more could I have asked for? Thanks Captain Ed

I ordered my first mattress topper a few weeks ago for one of the twin beds in my new Travato K and just loved it! It was a perfect fit and made exquisitely. A few minutes ago, I ordered another for the other twin bed in the RV. I highly recommend this product.
