The Short Answer
Buying a mattress online means committing to something you have never laid on. Lull answers that with a 365-night trial, free shipping, free returns, and free pickup if you send it back.
A full year is longer than almost anyone else offers, and it changes the calculation entirely. You are not guessing whether it works. You are testing it through every season before deciding.
The mattress itself is a well-built medium-firm foam bed at a price that undercuts the big showroom brands.
What Lull Mattresses Is
Lull is a direct-to-consumer mattress brand selling online rather than through showrooms. Mattresses arrive compressed in a box, and you unroll them onto your frame.
The no-frills approach is deliberate. Cutting out retail floor space and sales commissions is how the price stays below comparable showroom models, and it is the same playbook that made mattresses in a box a category in the first place.
The Lineup
| Model | Height | Feel | Best Suited To |
|---|---|---|---|
| Original Lull | 10 inches | Medium-firm, roughly 5 to 7 out of 10 | Back sleepers and anyone wanting classic memory foam feel |
| Luxe Hybrid | 15 inches | Medium, around 5 out of 10 | Sleepers who want foam comfort with coil support underneath |
All models come in Twin, Twin XL, Full, Queen, King, and California King. Affirm financing is available from around $27 a month.
What's Inside the Original Lull Mattresses
Three layers, each doing a specific job.
The knit cover is soft and breathable, letting air pass through rather than trapping it against you.
Gel-infused memory foam, 1.5 inches of it, sits directly under the cover. The gel infusion is there to help with airflow and pressure relief, which is what memory foam traditionally struggles with.
High-resilience foam forms the transition layer. This is what reduces motion transfer, so movement on one side of the bed does not travel across it.
Sink-resistant base foam provides the structural support and stops the mattress bottoming out under weight.
The design goal is contouring without the sinking feeling that puts people off memory foam. Reviewers generally report it achieves that.
Will It Fit How You Sleep?
This is the question that actually decides whether a mattress works, and it depends on position and body type more than anything else.
Back Sleepers
The strongest match. Medium-firm keeps the spine in neutral alignment while the foam layers still contour, which is exactly what back sleeping needs. Independent reviewers consistently rate this as the position Lull serves best.
Side Sleepers
Generally good, particularly for lighter and average-weight sleepers, since the contouring layers cushion the shoulder and hip. If you specifically want a plush, deep-sink shoulder cradle, the Original leans firmer than that, and the Luxe Hybrid is worth considering instead.
Stomach Sleepers
Works well for light to average-weight sleepers, where the firmer support keeps hips from dipping. Larger stomach sleepers have reported wanting more pressure relief, so weight matters more here than in other positions.
Couples
A genuine strength. The high-resilience layer limits motion transfer, so one person getting up does not wake the other. This comes up repeatedly in customer feedback and is one of the most practical benefits of an all-foam build.
Worth knowing: Lull lists a weight capacity of 250 pounds per person, or 500 pounds per couple.
The 365-Night Trial
This is the reason to consider Lull even if you are unsure.
You get a full year to sleep on it. If it does not work out, you arrange a return and Lull organizes pickup at no additional charge. Shipping was free going out, and returns are free coming back.
Most competitors offer 100 or 120 nights. A year means you experience the mattress through summer heat and winter cold, through a house move, through whatever your back does over twelve months. Almost nothing is left to guess.
The Original also carries a lifetime warranty. Terms differ across models and brands adjust them over time, so confirm the current warranty at checkout for whichever model you choose.
The First Two Weeks
A few practical things nobody mentions before delivery.
Unboxing. The mattress arrives compressed. Get it onto the frame before cutting the plastic, because it expands quickly once released.
New foam smell. Every compressed mattress has a mild scent out of the box. It fades within a few days. Air the room and it is a non-issue.
Break-in period. Foam softens slightly over the first couple of weeks as it adjusts to your body. Do not judge the feel on night one. Give it two weeks before forming an opinion, and remember you have 363 more nights to decide.
Frequently Asked Questions
How long is the Lull trial?
365 nights. If you are not satisfied, you arrange a return and Lull organizes pickup at no additional charge.

Medium-firm, roughly 5 to 7 out of 10. The Luxe Hybrid sits slightly softer at around 5 out of 10.
What warranty does Lull offer?
The Original carries a lifetime warranty. Coverage varies by model, so confirm the terms for your chosen mattress at checkout.

Final Verdict
Lull does the fundamentals well. A medium-firm foam mattress with genuine motion isolation, sensible layer construction, and a price that lands under most showroom equivalents.
What makes it easy to recommend is the 365-night trial paired with free returns and free pickup. Buying a mattress online is normally a leap of faith. Here you get a full year to decide, with nothing to lose if it turns out not to suit you.
Match it to how you sleep and it is a strong buy. Back sleepers and couples get the most out of it, side sleepers of average weight do well, and anyone wanting a very plush sink should look at the Luxe Hybrid instead. Whichever you pick, give it two weeks to break in before judging, and remember the calendar is firmly on your side.
