Yawnder reviews · 2015 review history · Updated October 2026
Our verdict
The Cirriform’s strongest result in Yawnder’s earlier review was comfortable summer sleeping with substantial quilted padding. Ben used it on a king bed with cotton sheets, open windows and a fan in a Minnesota home without central air. That is useful real-world context, but it does not establish a measured temperature drop or guarantee the same result with today’s Slumber Cloud pads.
Photos and review evidence
Who this design suits
Worth considering if
- You want a padded layer over a mattress whose support already works for you.
- You are comparing passive temperature-regulating bedding with ordinary quilted pads.
- You own the Cirriform and want the older model’s review context.
Consider another option if
- You need a surface temperature you can set and adjust.
- You expect a mattress pad to repair sagging or substantially change support.
- You want the cotton Cirriform test to stand in for a test of the current TENCEL-based Performance pad.
Our findings and practical takeaways
What the original use actually showed
The earlier account describes several nights of use during summer, with daytime temperatures in the mid-80s and nights around 65–70°F. Ben paired the pad with Brooklinen cotton sheets and reported staying comfortable. The windows, fan, sheets and room conditions are part of that result; this was not a controlled comparison that isolated the pad’s contribution.
That observation tells you how the product worked in one identifiable setup. It is more useful than a blanket promise that the pad will stop every sleeper overheating.
Padding, fit and everyday handling
The Cirriform was described as thick enough to fill the reviewer’s washing machine. A noticeably padded surface also means a bulkier item to wash and dry. Check your appliance’s capacity before buying a large quilted pad.
The reviewed specification listed a cotton surface, polyester fill and a fitted skirt for mattresses up to 20 inches. These are historical Cirriform specifications. Measure your mattress with any topper in place and compare it with the exact pad you are considering.
Passive cooling versus a powered system
Slumber Cloud describes Outlast as a phase-change material that absorbs excess heat and releases it as conditions cool. There is no powered water or air circuit in this pad. It is intended to moderate temperature swings, not refrigerate the sleep surface.
If your main problem is a heavy bedding stack, compare the pad together with your sheets and comforter. If you need adjustable heating or cooling, evaluate a powered system separately; its controls, maintenance and cost are different.
Cirriform versus the current Performance pad
The current Performance Mattress Pad lists a TENCEL Lyocell top with Outlast technology, polyester fill and a fitted skirt. That differs from the cotton surface described in the Cirriform review. Our older experience should not be presented as a new test of that product.
Use the manufacturer’s listing for the current fabric, dimensions and care label. Our Cumulus duvet review provides a separate historical Slumber Cloud test.

Frequently asked questions
Is this a test of the current Performance pad?
The firsthand account concerns the older Cirriform. The Performance listing is linked separately so you can compare materials without mixing the two generations.
Will it make a firm mattress plush?
The reviewer noticed padding, but a fitted pad is not a replacement for a substantial topper or a different support system.
Is the product image a new test photo?
No. It is a product image retained from the earlier coverage, labeled accordingly.
Manufacturer references checked October 2026: Current Performance specifications. These describe current listings or model history, separately from the original test.

Setting Up the Slumber Cloud Mattress Pad
Upon receiving the Slumber Cloud mattress pad, I was pleasantly surprised by its substantial thickness. It filled my entire washing machine, a testament to the generous padding it offers. Once on my king-sized bed, it not only elevated the comfort level but also added an aesthetic appeal to my bedroom decor. The visible square patches create a touch of elegance, enhancing the overall look of my mattress.
Experience the Temperature Regulation
Having slept on the Slumber Cloud mattress pad for several nights, I can attest to its remarkable temperature-regulating properties. Although I paired it with my Brooklinen cotton sheets, which are renowned for their breathability, the Slumber Cloud pad took my comfort to a new level during the hot Minnesota summer.
The high temperatures during the day hover in the mid-80s, dropping to around 65-70 at night. Without central air conditioning, I relied on open windows and a fan for relief. Historically, my previous mattress pads struggled to keep me cool, but the Slumber Cloud pad effectively maintained a comfortable temperature throughout the night.
Money-Back Guarantee
To ease any apprehension about investing in the Slumber Cloud mattress pad, the brand offers a 30-day money-back guarantee. If after several weeks you find this mattress pad doesn’t meet your expectations—though I can’t imagine why it wouldn’t—you have the option to return it for a full refund.
