The Best Bicycle Seats with Backrests for Adult Tricycles

The MOONCOOL is the seat most trike riders will find first, and its size is the reason: a 12 by 12 inch pad with a contoured shape that spreads weight over the sit bones rather than one point. It has high-density memory foam, a dual shock-absorbing system under the pad, and a PU leather cover that is waterproof and wipes clean. On a trike, where you cannot stand on the pedals to take a bump, that suspension matters more than it would on a bicycle.

The backrest slides up and down to meet your lumbar curve and can be removed, which makes it the only seat here you can run as a plain saddle on days you do not want it. It fits a standard 7/8 inch (22.2 mm) seat post, and the maker pitches it at tricycles as well as bicycles and exercise bikes. Next to the MEGHNA, it is wider and softer but has a simpler clamp, which is less flexible on an odd post. Next to the Relwears, it uses a dual shock system rather than elastomer springs.

It suits a rider who wants a wide, soft seat with a backrest that adjusts and that you can take off. The honest caveat is the post: a trike's seat post may not be 22.2 mm, so measure it before you buy, and re-tighten the clamp after the first rides because leaning back works it loose faster than a plain saddle.

The Relwears has extra padding and elastomer springs, a rubbery suspension that compresses and rebounds under the seat and takes the sting out of sharp joints and curbs. It is pitched at tricycles, electric vehicles and exercise bikes, and the seat is extra wide, so your hips sit in the pad rather than perched on it. The backrest is attached to the seat and gives support at the lumbar curve.

It will only fit a seat post with a top diameter under 23 mm, or 0.9 inches. That is a narrow window: it works for a 7/8 inch post and fails on anything larger. Compared with the MOONCOOL, it has a smaller owner record and a tighter fit range, but its springs are a different kind of cushioning, softer and more bouncy. Four screws are already mounted on the back of the cushion, and you tighten them evenly at both ends of the clamp.

It suits a rider who rides on rough pavement and has a post that fits. The caveat is the fit: measure the top of the post before you order, because a post that is even slightly too thick means a return. Keep the two clamp screws at the same gap, and check them again after the first rides.

The TIMCORR is an extra-large seat in soft memory foam with a high-density PU cover that is waterproof and stain-resistant, and a backrest whose height you adjust to suit your spine. It ships with a hex wrench and an open-end wrench, so you can fit it without hunting for tools. A solid connecting rod joins the backrest to the seat, which keeps it from rocking forward and back.

Its owner record is the shortest here, so there is far less evidence about how it ages than for the MOONCOOL. Next to the MEGHNA, it is built around a standard fit and has no removable clamp to rescue an odd post. That puts the weight of the decision on your post: the maker pitches it at tricycles, mountain bikes and electric bikes, but the post size is the thing to confirm.

It suits a rider who has a standard post and wants an easy setup with a roomy seat. The caveat is the thin record: watch the backrest rod and the stitching for the first few months, and keep the receipt in case the clamp or foam proves weaker than it looks.

The MEGHNA is a narrower seat than the MOONCOOL, at 11.5 by 9.5 inches, with a backrest of 8.75 by 8 inches. Its distinguishing feature is the clamp: the detachable saddle clamp can be removed, so the seat will fit a post that already has its own clamp, and the seat angle can be adjusted. That helps on a trike, where the post is often not the same as a bicycle's and a rider may want the seat tilted a little back.

The backrest height is set by loosening a button and sliding to the right height, and the seat has two shaped depressions to cradle the hips. Compared with the MOONCOOL, it is smaller and less cushioned, but the clamp is more adaptable. Compared with the Relwears, it has no spring suspension and relies on its foam core alone.

It suits a rider with an unusual seat post or one who wants control over the seat angle, with a mid-sized pad. The caveat is that its smaller seat may feel tight for a wider rider, and the removable-clamp setup needs more care to assemble, so check every bolt before the first ride.
