Thick, soft, perfect for my service dog to lay on in restaurants, etc.
Color: Blue, Style: 1/2 Inch
I bought this for my service dog to lay on in restaurants, etc. It's super thick and soft. I cut it in half and I'm using the other half for my dog to lay on in the car. Excellent quality and I love the carry strap.

Comfortable and thick mat that’s great for workouts at home
Color: Black, Style: 1/2 Inch, Color: Black, Style: 1/2 Inch
I picked up this Amazon Basics extra thick exercise mat for home workouts, and it’s been a solid addition. The thickness is the first thing you notice—it provides good cushioning, especially for exercises where you’re on your knees, elbows, or back. The surface has enough grip to keep you from slipping during most movements, whether you're doing stretching, core work, or basic workouts. It also stays in place pretty well on the floor without sliding around too much. The mat rolls out flat easily and comes with a strap, which makes it convenient to store or carry if needed. It’s lightweight enough to move around but still feels durable. It’s not a high-end studio mat, but for everyday workouts at home, it does exactly what you need it to do. Pros: • Extra thickness provides good cushioning • Comfortable for floor exercises • Lightweight and easy to store • Good value for the price Cons: • Slight compression over time with heavy use • Grip is good but not premium-level Overall, this is a great budget-friendly mat for home workouts, stretching, or basic fitness routines.

Maximum joint comfort and durability
Color: Pink, Style: 1/2 Inch
I absolutely loved the color, and it offers incredible cushioning without sacrificing stability during balance poses. It is dense, doesn't lose its shape, and springs back instantly. The materials are high-quality, and it doesn't have that strong plastic smell that others often have. It is worth every penny for the comfort it provides.

PLUSH! Fabulous yoga mat!
Color: Black, Style: 1/2 Inch
SO comfortable! It feels like a soft memory foam padding. I use it for several exercise classes and it is great for all of my needs! I love the strap it comes with to keep it rolled up in between classes and the ability to carry it anywhere.

very comfortable and thicker than a regular yoga mat
Color: Pink, Style: 1/2 Inch
This yoga mat is very comfortable and thicker than a regular yoga mat. The quality is excellent, and it doesn't have that strong rubber smell that many mats have. I'm very happy with it!
