Our Review Of The Popular Ironman Gravity 4000 Inversion Table

Ironman Gravity 4000 Inversion Table

Ironman Fitness has become a major player in indoor bicycles, ellipticals and inversion tables and have partnered with the famous Ironman triathlon to build their brand. In fact, it has a full line of 16 different tables for a wide range of needs and prices. The Ironman Gravity 4000 inversion table is one of the most popular models on the market today with a reasonable price and a reputation for comfort. But it does have its shortcomings as well according to some users. Is it a good option? Below, I review all its pros and cons and give my recommendation on whether you should consider this model.

Criteria Of A Quality Inversion Table

Two important criteria to consider when purchasing an inversion table are sturdiness and ease of use. When using the table, you should feel safe. Good models should not feel flimsy or like they could tip over. All the components should be made from high-end materials.

Comfort is an important factor as well. The table should have decent padding. Since you’ll be hanging by your ankles, the ankle supports should be comfortable as well. Lastly, a good table should be decently priced and should come with a warranty.

Product Overview

This inversion table has an extra wide, durable tubular steel frame. It has a 2.5 inch thick Memory-Foam vinyl covered backrest to provide superior comfort. There are extra-long safety handles that you can grab to control your level of inversion.

If you’re big or tall, this may be the table for you. It has the highest weight capacity of any model we've reviewed. It is able to support users as tall as 6’6” and up to 350 lbs. See the table on this page to compare different table features.

The product set up dimensions are 65in H x 26in W x 49in L and it’s foldable for storage. The folded dimensions are 80in H x 26in W x 17in D. Foldability is always a nice feature. Not everyone has the room to leave their table out all the time or wants to look at it in the corner.

This table includes an ergonomically designed ankle locking system. The ankle locking system has a "Palm Activated" ratchet to ensure comfort. There are also adjustable safety tether straps so you can control your maximum angle of inversion. This table allows you to invert up to 180 degrees, but also has three other adjustments for different starting inversion angles.

Check out the following video to review all the benefits of this table. Keep in mind it's from the manufacturer.


Users are generally positive about this table for several reasons. Compared to other tables, the price is reasonable. Users are also positive about the comfort level. With other tables, users often have to buy accessories to make it more comfortable. But with this table, it is comfortable as is.

Users also report that the table is quite easy to put together. Most say it will take you about 30 minutes to completely assemble.

Using the table is quite easy. A lot of users report that they like the extra-long safety handles as it makes it easier to pull themselves up from a full inversion. Also, because of the wide frame, users feel that the table is sturdy. They report that it doesn’t even wiggle when they move around on the table.

The Memory-foam padding also seems to make a big difference when it comes to comfort. Users feel supported because the back is sturdy, but soft. Many inversion tables seem to falter when it comes to the ankle supports. Users report that with this table, their ankles don’t feel like they are being pinched.


It’s not all rosy though. While the majority of users are positive, there are several recurring complaints. Customers report that the steel frame of the table is sturdy and seems to hold up. Unfortunately, though, it’s the smaller pieces that don’t seem to do so well.

Several users have noted that upon receiving the table, several pieces had broken during shipment. When they contacted the manufacturer to request new parts, the second shipment also arrived with the same broken pieces. It’s not clear if this is a problem with the manufacturer or the shipper but it’s an issue to consider. Others reported that some hardware was missing all together.

Several users report that while using the table, the safety tether straps have broken, causing the table to fully invert. This has left several users stuck in this position. Luckily, most of them had roommates or spouses that could come to their rescue.

Others have reported that while they were using the table, either the backing completely slid off or one of the side arms did not stay locked in place. It’s impossible to tell if this was an equipment malfunction or user error but it’s something to consider.

Other complaints have included the table being heavy. Even though it folds up, users report that it is still difficult to move. Some have said that if you didn’t have a back problem before, trying to move the table will definitely give you one.

Besides the lumbar support pillow, this table does not include or provide other accessories. Several other tables have accessories available for different needs. With this table, what you see is what you get.
