Self Inflating Mattress that fits in roof

I got mine from Sea to Summit the same a ArunAlec. On the invoice it’s called a
“Comfort Delux SI Size: Campervan Colour: Blue”

I haven’t tried fitting it in the van yet but I must admit I’m a bit disappointed in it, perhaps that will change once we use it. The valves are both at the shaped end which will make inflation/deflation difficult when it’s in the roof. I though that with it having two valves the mattress would be internally divided down the middle, so that I could lie on one side while I inflated the other. However it seems to be a single bag with two valves which makes it a basic design for a lot of money. Covid and the Scottish Government permitting we’re off to Scotland in April where we can give it a proper test and decide whether to love it or list it!
Oh that is a problem - both valves being at the wrong end of the bed. I thought the recent video showed the valves being opened at the right end - that is, so that you can inflate/deflate from the front of the van, without having to crawl up to the other end. This is a deal breaker!

How is it difficult when in the roof - just turn it the other way around with the valves towards the front seats - then you can inflate it by standing up downstairs using an electric pump hooked up to the power supply beside the sink and deflate it the same way - couldn't be easier . We sleep with our heads towards the front and the cut out bit is neither here nor there not unless you have a head where your shoulders are - the cut -out bit it is relatively small anyway !

With the mattress in the downstairs mode the two valves are at the back of the van. Just open the boot and you can top up/deflate from outside. We won’t be fully deflating the mattress so it will only be couple of pumps to top up. Do it at the same time as pulling up the blind and getting the duvet from the back.
If you are using it upstairs you can have the mattress with the valves whichever end you like.

After you spend some time on one you'll want to make it work. Inverting the mattress upstairs as already mentioned solves the access problem. They are super comfortable and I plan on using it as a temporary mattress at home, once my belongings arrive from the USA.

That’s good to know, I was wondering if having the cutout at the front would trap something at the back but if it can be turned round that’s problem solved.
 
Not having a separator down the middle can be an inconvenience as I weigh 95kg and Mrs Loz only 42, she can get thrown into the air if I roll over too quickly :)

I will have a good look at the C&M show next month and see what other vendors are doing.
I think a twin mat at 10cm thick would be ideal although the Small-double width products are hard to come by.

I wonder if 2 singles (as they are often wider) would be better?

If you did reverse it you could either have the corner scrunched up a bit or have the mattress located a few inches away from the door. The only problem with the former could be putting pressure on the cupboard door.

I think Keith was considering the inconvenience in the pop top.

Another option might be to use 2 regular sized S2S SI sleeping pads upstairs. These are available as 8cm and 5cm thick. The regular sized Comfort Delux would be too wide to double up upstairs.

The Comfort Plus is 51cm wide so doubling up makes them 102cm ie 13cm narrower than Deluxe Camper pad and 18cm short of the total width which to me would be a wasted space.

The Comfort Light is 5cm thick inflated (better when the poptop is closed) but 63.5cm wide. Given the coffin shape placing 2 in opposite directions might allow them to fit in the 120cm allowed. Not sure how well this option might work in practice.

The 2 single pads I linked to also have a 'womans' option, which I assume is a little softer to accommodate a lighter body mass.
However if you plan to use the pad upstairs and down, the Camper model is really the best option

Doh! A senior moment from me! In my mind I was thinking the cut out mattered upstairs. It’s back on my must have list.

Some of us are talking upstairs and some downstairs :)
The cutout totally makes sense downstairs, but might work fine upstairs with the valves towards the front..
 
Just a public service announcement - if you have a self-inflating mattress then do not store it for long periods of time super squashed or having sucked every ounce of air out - it will lose its ability to expand because the foam/springs become permanently compressed. So you will find it does not self-inflate fully any more and its insulating properties will be lost.

This is well known in the camping world - sleeping bags, self inflating mattresses or basically anything that is foam, down or springs should be long term stored in at least a semi-inflated state.

Those storing in the roof with the standard mattress removed will be OK I am sure but if you suck everything out of it to store it in there with the original mattress then dont do that for long periods of time.

Jusr saying... I ignored the advice and ended up having to replace a sleeping bag and mattress that were previously great for camping.

Thanks very much for this advice - I guess it’s a question of judging how much air to leave in. Certainly I wouldn’t be interested in buying the mattress if I couldn’t leave it in situ.

I just partially deflate then roll or fold into 3 and leave on the rear shelf. The instructions that come with the mat say it should be left inflated when stored, which is a bit of a pain.
Despite the negative aspects I don’t think any other offerings, Duvalay etc, would be any less of a problem as far as storage.

Interesting post. Just wondered where you got this information from? Was it direct from the makers?
What happens to the brand-new mattress sitting on the shelf for months before being sold?

Yes, I have read that too. What I'm asking is where he got the information from? The user manual as you have shown states "PU foam can form a memory" key here is can, the supplied manual does not state: "it will lose its ability to expand because the foam/springs become permanently compressed"
Not being "picky" would just like to know from where this information comes from?
 
From multiple sources over the years. Its even worse with down products than foam.

But its just common sense when you think about it - if you keep products compressed for long periods, they lose their springiness.

You can find all sorts of references, e.g.:


5. How long can you keep a memory foam mattress in the box?


Ideally one should unbox the foam mattress within 3-4 days of arrival. However, the time frame varies from brand to brand.


The exact duration for which you can keep a memory foam mattress in the box is mostly indicated by the manufacturer which may approximately range somewhere between less than a week to 3 months.


One should also be aware of the risks involved with a long waiting period to unbox the mattress that are as follows:


  • The memory foam mattress might not expand fully,
  • Possibility that the foam may not feel the same.
  • You could end up voiding the warranty.

What Will Happen If Memory Foam Mattress Stays in a Box for Too Long?​

Memory foam mattresses have a certain time under which they should be unboxed, as said earlier. But, what are the consequences? Here we review the potential risks of leaving a mattress in the box for too long.

1. Damage to Mattress
Memory foam mattresses usually consist of multiple foam layers. Some include support foam, gel foam, comfort foam, base foam, and others. All these layers together form a memory foam mattress and make it sit together nicely.

If the mattress spends too much time encased, folded, and rolled, the memory foam inside of it may start losing its contouring properties and not feel so comfortable once you start laying on it.

Companies that allow for longer enclosure of memory foam mattresses usually use a better quality foam that is more durable and can last longer in such conditions. Still, not all companies can guarantee that.

There’s a good reason why we don’t wash memory foam products. For example, it’s not advisable to wash memory foam pillows in the washing machine, as the material could degrade. The same goes for compressed memory foam. It could start losing its properties and qualities over time.

2. It Won’t Expand​

As we said earlier, memory foam sits compressed for more convenient shipping and placement at home. That also makes it easier to carry and store, unlike innerspring mattresses that feel huge. However, if you keep it rolled and compressed for too long, the memory foam quality will not only degrade but also disallow the mattress from expanding.

Usually, after getting a memory foam mattress, it can take between 24 hours and up to 3 days for it to completely expand. It may either take a ridiculously long time to expand over your bed’s frame or expand only partially, leaving other parts of the mattress either too soft or degraded.
 
Has anyone tried these?

or 2 of the red singles for a better fit, both are 10cm thick.
2x single red ones would be 6cm too wide for the poptop. The 7.5cm should work though, as they are only 60cm wide. The egg crate foam insert isn't going to be as comfortable as the delta in the S2S.
 
Hi Keith, We store the S2S mattress in the Ocean roof with the factory mattress removed. We tend to sleep downstairs so I roll it once to expel some of the air first before laying it flat on the roof slats for storage.

Thanks for clarifying that this is a replacement job rather than a topper. Is it lots better than the original mattress? I don’t think we’ve slept “upstairs” yet as prefer the larger double “downstairs” but intend to use it this year.

I've had my old camping original Thermorest self inflating mattresses for over 30 years and they have both been stored fully deflated and rolled after every use and sometimes not reused for years but both still work fine and I now use them in my Cali pop top under the original mattress to provide a comfortable sleep. They are only 2cm when inflated but provide great comfort and can be deflated whilst laying in bed and left stored in the pop top whilst travelling without damage or water ingress over the last 10,000 miles :)

We sleep downstairs with the S2S on top of the comfort mattress and only store the S2S in the roof. We originally used a memory foam topper, which was a little better for us than the comfort mattress alone, but found swapping the topper for the S2S was a big improvement, for us anyway.
