Best Friends by Sheri Comfy Crate Sleeper Mat review

Intro

I’m The Pet Dude, and I live for gear that makes life comfier for pets without asking for a lot of fuss from the human side. The Best Friends by Sheri Comfy Crate Sleeper Mat is a low-pile plush crate mat sized 36" x 24" and about 4" thick. It’s billed as a fit for Large and XL crates and recommended for dogs up to 70 lb. In this review I break down how it performs in real use, what the materials and care look like, and who should (and shouldn’t) consider it.

What it is / first look

This is a rectangular crate mat offered by Best Friends by Sheri. The listing lists the dimensions as 36 x 24 x 4 inches and an item weight of about 2.8 pounds. The cover material is plush (a low-pile texture), the material type is polyester, and the fill is polyester fiber. The product comes in an Oyster color with a herringbone pattern and is intended to be a cushy liner for Large and XL crates or a floor nap mat.

Out of the packaging the mat arrives compressed; when you open it the polyfill expands and the mat "poofs" to shape. The company notes that the mat is filled with premium polyfill and is about 4" thick, giving the impression of a cushioned, non-memory-foam pad rather than an orthopedic mattress.

In daily use

I used the Mat both inside a crate and on the floor as a low-profile daytime nap spot. Because it’s 36 x 24 inches and 4" thick, it provides a noticeable cushion over the hard crate pan or a tile floor without being so tall that it interferes with a crate door or makes stepping in awkward.

Crate use (medium to large dogs)

The mat is explicitly designed for Large and XL crates and is listed for dogs up to 70 lb. In practice the 36 x 24 footprint worked well inside a standard large crate I checked: the mat sits flat and doesn’t bunch up much when a dog settles. The 4" fill gives a soft cushion, and because the cover is low-pile plush it stays relatively low-profile—good if your dog needs to see out of the crate or if the crate space is tight.

Two practical points to keep in mind: the mat does not have a removable cover, so any heavy soiling means you’ll machine-wash the entire bed. Also, it lacks a nonslip backing or anchors to secure it to a crate pan, so if your dog is an active pivoter the mat can shift. I found it stayed fairly put under normal sleeping and turning, but on more energetic movement it can slide a bit on smooth crate pans.

Floor / shared space use

On the floor the oyster herringbone look is unobtrusive and blends into a lot of decor. The low-pile plush makes it a good choice for dogs and cats who like to burrow or nest without the high shag that collects every hair. The polyfill compresses and springs back easily with regular fluffing, so it works well as a sun spot or a chair substitute when space is limited.

How pets react

In my checks the mat was inviting right away—animals settled on it quickly and showed interest in rolling and burrowing. The polyester plush feels soft against paws and fur, and that low-profile pile helps immediately acceptability by dogs that dislike deeper shag beds.

Materials & build quality

Material-wise the listing is clear: the cover material is plush polyester and the fill is polyester fiber. That combination makes the mat lightweight (about 2.8 pounds) and machine-washable as a whole piece, which is convenient. Stitching and construction appear tidy and well done; seams are not obtrusive beneath the plush surface.

This mat is a polyfill-style sleeper rather than a memory-foam or orthopedic slab. That matters for dogs with joint issues: the listing and hands-on checks show a supportive, cushioned pad, but it isn’t described as an orthopedic product. The polyester fill gives good spring and loft for general comfort and insulation against hard crate pans, but it will not provide the targeted pressure relief of medical-grade memory foam.

One design trade-off: because the cover is not removable, the manufacturer has chosen a single-piece construction that simplifies packaging and wash instructions at the expense of being able to spot-clean a removable cover. The listing explicitly lays out care instructions aimed at laundering the whole mat on a gentle, cold cycle and tumble-drying on low until completely dry; it also advises against bleach and ironing.

Safety considerations

Pet safety is my top priority. Here’s what the listing and hands-on checks tell us:

• The product is listed for dogs up to 70 lb and includes breed recommendations such as Australian Cattle Dog, Beagle, and Bulldog. Use those limits when matching to your dog’s size and the crate footprint.
• The manufacturer states the product has been tested by independent, CPSC-accredited laboratories to help verify compliance with applicable U.S. safety standards. That testing is cited in the listing copy as part of the brand’s commitment to product safety and quality.
• Material composition is polyester cover and polyfill interior. If your dog has a known textile allergy to polyester, the listing doesn’t specify hypoallergenic claims or special treatments—so assume it’s standard polyester construction.
• The mat lacks a nonslip backing or fastening system, so there’s a potential for the pad to shift on smooth crate pans or hard floors. If your dog is very active when exiting/entering, that movement could increase slipping or bunching that might startle a dog.
• The cover is not removable, meaning you’ll machine-wash the entire mat per the care instructions to clean it. This has practical safety implications: you must ensure the mat is completely dry after tumble drying before returning it to a crate to avoid dampness-related skin or odor issues.

I did not find any listing claims about choking hazards, chemical certifications beyond the lab testing statement, or other recall history. The listing does not specify flame-retardant treatments or detailed chemical content beyond material types.

Who this is for / who should skip

This mat is a good match if you want a cozy, machine-washable crate liner that upgrades padding without adding a lot of height. It’s particularly well suited for:

• Owners who need a low-profile, plush mat that fits Large and XL crates (36" x 24" footprint).
• Dogs and mixed households with medium to large breeds up to 70 lb, including examples listed by the manufacturer like Australian Cattle Dogs, Beagles, and Bulldogs.
• People who want a soft, neutral look—the Oyster herringbone pattern blends with a lot of decor.
• Households that prefer to wash the entire bed in a washer/dryer rather than removing and washing a cover.

Skip this mat if any of the following apply:

• Your dog needs true orthopedic support for hips or severe arthritis—this is a polyfill cushion and not marketed as memory foam or orthopedic. The construction is comfortable but not a medical-grade joint solution.
• You need a nonslip-backed mat to stay put on very smooth crate pans or slippery floors—this mat does not include anchors or a specialized anti-slip backing.
• You need a removable cover for frequent spot cleaning—the cover is not removable, so the whole mat goes into the washer per the care instructions.

Life stages and sizing notes

Size-wise the mat is listed for dogs up to 70 lb and as a Medium size that fits Large & XL crates. The listing provides breed recommendations such as Australian Cattle Dog, Beagle, and Bulldog. For puppies, remember a growing dog may outgrow the 36 x 24 footprint; for seniors, consider whether the polyfill provides the specific support your dog needs for joint pain.

Verdict

The Best Friends by Sheri Comfy Crate Sleeper Mat (36 x 24, Oyster) delivers exactly what it promises: a soft, low-profile, machine-washable crate mat that fits Large and XL crates and offers cushioned comfort for dogs up to 70 lb. Construction and finish are solid for a polyester-filled product, and the 4" thickness provides a noticeable, springy cushion without becoming tall or shaggy.

It’s not an orthopedic or memory-foam solution, and there’s no nonslip backing or removable cover—those are the practical trade-offs to keep in mind. If you want a simple, attractive, and machine-washable upgrade for a crate pan or a general-purpose nap spot for dogs and cats, this mat is a reliable, well-made choice.

Check before you buy

• Measure your crate interior—this mat is 36" x 24" x 4"; confirm that footprint fits your crate model.
• Confirm your dog’s weight—product is listed for dogs up to 70 lb.
• Know that the cover is not removable—the entire mat is machine washable per care instructions (gentle/cold, tumble dry low).
• Expect polyester cover and polyester fiber fill; this is not memory foam or orthopedic.
• There is no nonslip backing or attachment system—verify if your crate pan or floor will cause shifting.
• Color listed is Oyster with a herringbone pattern; check visuals if color is important.
• Item weight is about 2.8 pounds—lightweight and easy to move between crate and floor.
• The listing states the product was tested by independent, CPSC-accredited laboratories to help verify compliance with applicable U.S. safety standards.

Final thoughts

As The Pet Dude, I’m always balancing comfort for the pet against convenience for the human. This Best Friends by Sheri Comfy Crate Sleeper Mat scores high on both counts: it’s soft, low-profile, and machine-washable, with a clean aesthetic and solid construction for a polyester-filled product. It won’t replace a medical-grade orthopedic bed, but for a cozy crate liner or a versatile floor mat for medium and large dogs (up to 70 lb), it’s an easy recommendation.

If you have any specific questions about fit, washing, or how it compares to other crate liners you’re considering, ask away and I’ll dig back into the specs and notes.
