Amazon Basics 1/4 Inch TPE vs Retrospec Solana 1": Which One Should You Buy?

The Amazon Basics 1/4 Inch TPE lists at $26.36. It is 6 mm of TPE, 73.6″ × 24″, and weighs 2 pounds. The Retrospec Solana 1″ lists at $39.99 for a full inch of NBR foam, 72″ × 24″, at 4 pounds.

Go row by row and the cheaper mat wins most of them. It weighs half as much, runs 1.6 inches longer, and carries a one-year warranty to Retrospec’s six months. The Solana is more than four times as thick and comes in far more colors. That leaves one thing to weigh: whether about 19 extra millimeters of foam are worth giving up the rest.

Retrospec aims the Solana at knees, spine, elbows and hips, and Amazon’s review summary agrees: knee support is what owners praise most. If you kneel on tile or concrete, have joints that already ache on a normal mat, or do physio exercises lying on your back, an inch of foam does something 6 mm can’t.

The Amazon Basics isn’t bare floor, though. Its review summary says owners find it comfortable and like the thickness, and on wood or carpet 6 mm of springy TPE handles tabletop and short kneeling holds. The gap opens on hard floors and in long holds.

Stand on one foot and the order flips. Soft NBR keeps compressing as your weight shifts from heel to toes, and at 25 mm there is a lot of it to sink through, so your ankle keeps correcting in tree pose and warrior three. Amazon’s review summary for the Solana 1″ includes owners who find it hard to balance on.

The TPE is also the denser mat. By our arithmetic it packs 2 pounds into about a quarter of a cubic foot, while the Solana spreads 4 pounds over a full one, so the thin mat carries roughly twice the material per cubic inch. It gives a little and pushes back. Amazon credits that spring-back with helping balance, which is its own claim, but the TPE is clearly the steadier of these two under a standing foot.

Amazon calls its TPE mat multi-purpose, ideal for yoga, Pilates and general fitness. Retrospec lists yoga flows, mat Pilates, somatic stretching and any floor workout. On paper they cover the same ground.

In practice they split it. Pilates mat work keeps you on your back a lot, with rolling exercises that press the spine into the floor, and that is where the inch pays off. A vinyasa flow that keeps moving between standing, plank and down dog suits the thinner mat, since hands sink into soft foam the same way feet do. Push-ups and bodyweight strength work point to the TPE for the same reason.

GearLab hasn’t tested either mat, so there are no grip numbers. Amazon’s review summary says TPE owners like the grip and find the surface doesn’t slip. The summary for the Solana 1″ says nothing either way about its top, and Retrospec says the ribbed surface keeps you steady.

Neither foam absorbs sweat, so once your palms are damp a film sits on top and traction drops. For heated classes, look elsewhere; our GRP Adapt 2.0 vs Solana 1″ page covers GearLab’s top wet-grip mat.

Retrospec’s copy calls the Solana lightweight and portable, and its Amazon bullet talks about taking it from home practice to studio salutations. It weighs twice as much as the Amazon Basics, and rolled up, an inch of foam makes a tube close to ten inches thick, too fat for a normal mat bag.

Amazon’s review summary also has Solana 1″ owners reporting that the nylon strap wasn’t in the box, which matters more on a roll that size. The Amazon Basics rolls into a slim tube with its carrying strap and goes to class easily. For a mat that never leaves home, weight and bulk count for much less.

Retrospec warns that the Solana might give off a harmless smell at first and suggests unrolling it to air for a day or two. There is a lot of foam here, so give it the full two days. Its cleaning advice is soap and water, a wipe, and hanging the mat up to dry, never soaking it.

Amazon lists the TPE as hand wash only, and a damp cloth covers most of that since nothing soaks in. Heat and hours of sun are hard on TPE, so keep it out of a parked car and away from a bright window.

Amazon Basics covers its mat for 1 year. Retrospec covers the Solana for 6 months against manufacturing defects. Don’t expect either to treat flattened foam as a defect. NBR this deep takes a lasting dent wherever your knees and heels press hardest.

Returns depend on where you buy. Both listings were shipped and sold by Amazon when we checked, so an Amazon order falls under Amazon’s policy. Retrospec’s own store takes returns within 30 days only on unused mats in their packaging.

List prices are $26.36 and $39.99. Each color carries its own price on Amazon, so check the Amazon Basics TPE and the Solana 1″ in the color you want. Retrospec also sells the Solana direct at retrospec.com, where the list price is the same.

The Solana comes in 13 colorways at last count, the Amazon Basics in Aqua, Plum, Rose and Black. When we checked, the Solana 1″ had about 15,000 ratings at 4.5 stars and the TPE about 980 at 4.6.

If an inch sounds like too much, Retrospec’s half-inch Solana against this TPE mat is a closer contest, and Amazon’s own inch-thick pad against the TPE has its own page.

Buy the Amazon Basics TPE for yoga, mixed workouts, or any routine with standing poses, planks or push-ups, and for a mat that has to travel. It is $13.63 cheaper, half the weight, and covered for twice as long.

Get the Solana 1″ when the mat’s main job is protecting joints: kneeling on a hard floor, physio, Pilates on your back or gentle floor work. Expect it to wobble under one foot, roll up huge and come with six months of cover.
