Sea to Summit Comfort Deluxe Self-Inflating Mat Review

Our Verdict: Sea to Summit Comfort Deluxe Self-Inflating Mat

One of the most comfortable pads in the test and it comes in singles and doubles, but the foam is slow to compress and hard to cram back in the sack.

A 4.25 inch self-inflating foam mat rated around R 5.2 to 7, it balances plush comfort with size options that make it the most flexible pick here.

What's the bottom line?

About 4.25 inches of foam gives a plush, even surface that hides ground bumps.

One tester slept on three pads over three nights and called this the most comfortable of the lot.

It is the comfiest pad I tried all season, but I never once got the double folded back into its bag without a fight.

Our Analysis, Comparisons, and Test Results

The Sea to Summit Comfort Deluxe Self-Inflating Mat scored 87 out of 100 overall.

It is strongest on comfort and weakest on packed size.

Here is how it did on every metric we tested, with exactly how each score compares to the rest of the field.

Comfort

About 4.25 inches of foam gives a plush, even surface that hides ground bumps.

One tester slept on three pads over three nights and called this the most comfortable of the lot.

The delta-core foam feels supportive rather than bouncy like an air pad.

Vertical side walls keep the sleeping area flat to the edge.

Comfort	Rating
Best in test	10/10
Sea to Summit Comfort Deluxe Self-Inflating Mat	10/10
Category average	7.9/10
Worst in test	6/10

Ease of use

It self-inflates in about 10 minutes in cool weather and faster on a warm afternoon.

Foam does not compress quickly, so morning pack-down is the slow part.

Here's what that means:

Testers often could not fit the double back into its snug stuff sack on the first try.

You top it off by mouth for a firmer feel.

Worst in test	6/10

Warmth

R-value is quoted around 5.2 on older units and up to about 7 on newer ones, solid three-season warmth.

The continuous foam blocks cold from the ground well on chilly nights.

Warm enough for spring through autumn car camping.

Not the top R-value here but comfortably warm for most trips.

Worst in test	4/10

Versatility

Offered in single and double widths, so it fits solo campers and couples alike.

Comfortable and warm enough to cover most car-camping conditions.

Too heavy and bulky for backpacking, like the other foam mats.

Packed Size

Regular packs to roughly 7.5 by 31 inches, a large roll typical of thick foam pads.

The double is bulkier still and grunts back into its top-loading sack.

Plan trunk space, this is not a pack-it-small pad.

What Other Camping Mattresss Should You Consider?

Not sold on this one? A few others from our testing are worth a look.

The Therm-a-Rest MondoKing 3D Self-Inflating Mattress is our best foam-reinforced mattress. The most comfortable and warmest self-inflating pad here, but it is heavy and packs down to a fat roll you will only ever want near the car.

The Exped MegaMat Duo Queen Self-Inflating Mattress is our best heavy-duty mattress for couples. A near-bed for two people with the warmest rating here, but it is heavy, slow to pack, and swallows most of your trunk.

The Coleman Silver Springs Self-Inflating Pad is our best bang-for-buck low-maintenance mattress. A cheap, low-maintenance self-inflating pad with decent warmth for the price, but it is narrow and thin so it will not hide rough ground.
